• Problems installing PIL after OSX 10.9

  - by user2632417

  I installed Mac OSX 10.9 the day it came out. Afterwards I decided I needed to install PIL. I'd installed it before, but it appeared the update had broken that. When I try to use pip to install PIL, it fails when building _imaging. It appears the root cause is this. /usr/include/sys/cdefs.h:655:2: error: Unsupported architecture Theres also a similar error here: /usr/include/machine/limits.h:8:2: error: architecture not supported and here: /usr/include/machine/_types.h:34:2: error: architecture not supported Then there's a whole list of missing types. /usr/include/sys/_types.h:94:9: error: unknown type name '__int64_t' typedef __int64_t __darwin_blkcnt_t; /* total blocks */ ^ /usr/include/sys/_types.h:95:9: error: unknown type name '__int32_t' typedef __int32_t __darwin_blksize_t; /* preferred block size */ ^ /usr/include/sys/_types.h:96:9: error: unknown type name '__int32_t' typedef __int32_t __darwin_dev_t; /* dev_t */ ^ /usr/include/sys/_types.h:99:9: error: unknown type name '__uint32_t' typedef __uint32_t __darwin_gid_t; /* [???] process and group IDs */ ^ /usr/include/sys/_types.h:100:9: error: unknown type name '__uint32_t' typedef __uint32_t __darwin_id_t; /* [XSI] pid_t, uid_t, or gid_t*/ ^ /usr/include/sys/_types.h:101:9: error: unknown type name '__uint64_t' typedef __uint64_t __darwin_ino64_t; /* [???] Used for 64 bit inodes */ Needless to say I don't know where to go from here. I've got a couple of guesses, but I don't even know how to check. Wrong include probably as a result of a badly configured environment variable Problem with Xcode's installation/ missing command line tools Messed up header files If anyone has any suggestions either to check one of those possibilities or for one of their own I'm all ears.

• Boost::Thread linking error on OSX?

  - by gct

  So I'm going nuts trying to figure this one out. Here's my basic setup: I'm compiling a shared library with a bunch of core functionality that uses a lot of boost stuff. We'll call this library libpf_core.so. It's linked with the boost static libraries, specifically the python, system, filesystem, thread, and program_options libraries. This all goes swimmingly. Now, I have a little test program called test_socketio which is compiled into a shared library (it's loaded as a plugin at runtime). It uses some boost stuff like boost::bind and boost::thread, and it's linked again libpf_core.so (which has the boost libraries included remember). When I go to compile test_socketio though, out of all my plugins it gives me a linking error: [ Building test_socketio ] g++ -c -pg -g -O0 -I/usr/local/include -I../include test_socketio.cc -o test_socketio.o g++ -shared test_socketio.o -lpy_core -o test_socketio.so Undefined symbols: "boost::lock_error::lock_error()", referenced from: boost::unique_lock<boost::mutex>::lock() in test_socketio.o ld: symbol(s) not found collect2: ld returned 1 exit status And I'm going crazy trying to figure out why this is. I've tried explicitly linking boost::thread into the plugin to no avail, tried ensuring that I'm using the boost headers associated with the libraries linked into libpf_core.so in case there was a conflict there. Is there something OSX specific regarding boost that I'm missing? In my searching on google I've seen a number of other people get this error but no one seems to have come up with a satisfactory solution.

• OSX launchctl programmatically as root

  - by Lukas1

  I'm trying to start samba service using launchctl from OSX app as root, but I get error status -60031. I can run without problems the command in Terminal: sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.AppleFileServer.plist` In the objective-c code, I'm using (I know it's deprecated, but that really shouldn't be the issue here) AuthorizationExecuteWithPrivileges method. Here's the code: NSString *command = @"launchctl"; // Conversion of NSArray args to char** args here (not relevant part of the code) OSStatus authStatus = AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &_authRef); if (authStatus != errAuthorizationSuccess) { NSLog(@"Failed to create application authorization: %d", (int)authStatus); return; } FILE* pipe = NULL; AuthorizationFlags flags = kAuthorizationFlagDefaults; AuthorizationItem right = {kAuthorizationRightExecute, 0, NULL, 0}; AuthorizationRights rights = {1, &right}; // Call AuthorizationCopyRights to determine or extend the allowable rights. OSStatus stat = AuthorizationCopyRights(_authRef, &rights, NULL, flags, NULL); if (stat != errAuthorizationSuccess) { NSLog(@"Copy Rights Unsuccessful: %d", (int)stat); return; } OSStatus status = AuthorizationExecuteWithPrivileges(_authRef, command.UTF8String, flags, args, &pipe); if (status != errAuthorizationSuccess) { NSLog(@"Error executing command %@ with status %d", command, status); } else { // some other stuff } I have also tried using different flags then kAuthorizationFlagDefaults, but that led to either the same problem or error code -60011 - invalid flags. What am I doing wrong here, please?

• Reading a ZFS USB drive with Mac OS X Mountain Lion

  - by Karim Berrah

  The problem: I'm using a MacBook, mainly with Solaris 11, but something with Mac OS X (ML). The only missing thing is that Mac OS X can't read my external ZFS based USB drive, where I store all my data. So, I decided to look for a solution. Possible solution: I decided to use VirtualBox with a Solaris 11 VM as a passthrough to my data. Here are the required steps: Installing a Solaris 11 VM Install VirtualBox on your Mac OS X, add the extension pack (needed for USB) Plug your ZFS based USB drive on your Mac, ignore it when asked to initialize it. Create a VM for Solaris (bridged network), and before installing it, create a USB filter (in the settings of your Vbox VM, go to Ports, then USB, then add a new USB filter from the attached device "grey usb-connector logo with green plus sign")  Install a Solaris 11 VM, boot it, and install the Guest addition check with "ifconfg -a" the IP address of your Solaris VM Creating a path to your ZFS USB drive In MacOS X, use the "Disk Utility" to unmount the USB attached drive, and unplug the USB device. Switch back to VirtualBox, select the top of the window where your Solaris 11 is running plug your ZFS USB drive, select "ignore" if Mac OS invite you to initialize the disk In the VirtualBox VM menu, go to "Devices" then "USB Devices" and select from the dropping menu your "USB device" Connection your Solaris VM to the USB drive Inside Solaris, you might now check that your device is accessible by using the "format" cli command If not, repeat previous steps Now, with root privilege, force a zpool import -f myusbdevicepoolname because this pool was created on another system check that you see your new pool with "zpool status" share your pool with NFS: share -F NFS /myusbdevicepoolname Accessing the USB ZFS drive from Mac OS X This is the easiest step: access an NFS share from mac OS Create a "ZFSdrive" folder on your MacOS desktop from a terminal under mac OS: mount -t nfs IPadressofMySoalrisVM:/myusbdevicepoolname  /Users/yourusername/Desktop/ZFSdrive et voila ! you might access your data, on a ZFS USB drive, directly from your Mountain Lion Desktop. You might play with the share rights in order to alter any read/write rights as needed. You might activate compression, encryption inside the Solaris 11 VM ...

• Custom Icon for NFS Volume Mount - Possible for OSX?

  - by James

  We are naming our various network volumes after Planets! I renamed the Mercury.icns icon, to .VolumeIcon.icns and copied it over to the mount point folder of the NFS server. So far remounting the NFS share does not seem to employ this icon. Looking on the NFS server, there appears to be two VolumeIcon files. Can someone tell me what I am doing wrong? Permissions? Do I need a .DS_Store file there as well?? It shouldn't be this hard! EDIT: Should have mentioned, the NFS server is Ubuntu 12.04.1. NOT an OSX server.

• When a python process is killed on OSX, why doesn't it kill the child processes?

  - by Hugh

  I found myself getting very confused a while back by some changes that I found when moving Python scripts from Linux over to OSX... On Linux, if a python script has called os.system(), and the calling process is killed, the called process will be killed at the same time. On OSX, however, if the main process is killed, anything that it launched is left behind. Is there something somewhere in OSX/Python where I can change this behaviour? This is causing problems on our render farm, where the processes can be killed from the management GUI, but the top level process is really just a wrapper, so, while the render farm management might think that the process has gone and the machine is freed up for another task, the actual processor-intensive task is still running, which can lead to huge blockages. I know that I could write more logic to catch the kill signal and pass it on to the child processes, but I was hoping that it might be something that could be enabled at a lower level.

• How can I use fetchmail (or another email grabber) with OSX keychain for authentication?

  - by bias

  Every fetchmail tutorial I've read says putting your email account password clear-text in a config file is safe. However, I prefer security through layers (since, if my terminal is up and someone suspecting such email foolery slides over and simply types "grep -i pass ~/.*" then, oops, all my base are belong to them!). Now, with msmtp (as opposed to sendmail) I can authenticate using the OSX keychain. Is there an email 'grabber' that lets me use Keychains (specifically the OSX keychain) or at least, that lets me MD5 the password? This is a duplicate of my unanswered question on serverfault. I've put it on superuser because I'm doing this on a personal computer (viz. with OSX) so it's more of a superuser question.

• How can I get the mount path of a USB device on OSX?

  - by xastor

  I have a backup script that backs up some data to a USB device. The problem I have is that OSX sometimes changes the expected mount path. For example if some file is locked under the expected mount path, OSX mounts it on another path. A USB device named 'BACKUP' can be mounted at /Volumes/BACKUP-1 instead of /Volumes/BACKUP. Is there a way to finding out the current mount path of a USB device in the OSX Terminal? Something like 'mount_path BACKUP' (command is fake) which would then return '/Volumes/BACKUP-1' or nothing if the device was not mounted?

• What Filesystem should be used for a 4TB drive for both Windows and OSX compatibility? [closed]

  - by Nicholas Yost

  Note: I am aware of similar questions. The one's I seen here are for Windows, OSX, and Linux (which I do not need). I also can use Mountain Lion, which the other questions did not mention. I was going to use NTFS, but OSX Mountain Lion can only read that filesystem and not write to it for some reason. I want to use something native between OSX and Windows, as I don't want to risk losing the data over filesystem incompatibilities. I have USB 3.0 and want something that will allow files greater than 4GB. I do not mind installing a small set of drivers on the Windows machine(s), but I would strongly prefer to leave the Mac machine untouched. Thanks!

• OSX, G/AWK, Bash - "illegal statement"

  - by S1syphus

  I have a script that somebody from SO kindly provided to solve an issue I was having, However, I'm having some issues getting it to work on OSX. gawk --version GNU Awk 3.1.6 awk --version awk version 20100208 The original source is: awk -F, -vOFS=, -vc=1 ' NR == 1 { for (i=1; i<NF; i++) { if ($i != "") { g[c]=i; f[c++]=$i } } } NR>2 { for (i=1; i < c; i++) { print $1,$2, $g[i] > "output_"f[i]".csv } }' data.csv When I run the script it gives the following error: awk: syntax error at source line 12 context is print $1,$2, $g[i] > >>> "output_"f <<< [i]".csv awk: illegal statement at source line 13 From the look of it the variable of [i] isn't been amended to the output file, but I don't know why. If I change AWK to GAWK and run the original script here is the output: gawk: cmd. line:11: print $1,$2, $g[i] > "output_"f[i]".csv gawk: cmd. line:11: ^ unterminated string So I edit the relevant line to fix the unterminated string print $1,$2, $g[i] > "output_"f[i]".csv" Then it runs through fine produces no errors, but there is no output files.

• Using OSX home directories from linux

  - by Steffen

  I'm running an OSX (Snow Leopard) Server with OpenDirectory, which is nothing else than a modified OpenLDAP with some Apple-specific schemas. However, I want to reuse this directory on some of my Linux (Debian Squeeze) boxes. It's no problem to authenticate against OSXs LDAP Server, this works fine already. What I struggle with is the way the home folders are specified in OSX. If I query the passwd config on one of my linux machines, the OSX imported entries are looking like this myaccount:x:1034:1026:Firstname Lastname:/Network/Servers/hostname.example.com/Volumes/MyShare/Users/myaccount:/bin/bash While those network home folders might be fine for OSX-Clients, I don't want those server based paths on my linux machines. I saw that there is an NFSHomeDirectory Attribute in the OSX User inspector, but if I change this the whole user home path gets changed. Since my users should be able to login on both systems, OSX and Linux, this is not what I want. Does anyone have an idea how I must configure OSX to make my linux machines use home folders like /net/myaccount and leave the configuration for OSX clients untouched?

• How do I add Objective C code to a FireBreath Project?

  - by jmort253

  I am writing a browser plugin for Mac OS that will place a status bar icon in the status bar, which users can use to interface with the browser plugin. I've successfully built a FireBreath 1.6 project in XCode 4.4.1, and can install it in the browser. However, FireBreath uses C++, whereas a large majority of the existing libraries for Mac OS are written in Objective C. In the /Mac/projectDef.make file, I added the Cocoa Framework and Foundation Framework, as suggested here and in other resources I've found on the Internet: target_link_libraries(${PROJECT_NAME} ${PLUGIN_INTERNAL_DEPS} ${Cocoa.framework} # added line ${Foundation.framework} # added line ) I reran prepmac.sh, expecting a new project to be created in XCode with my .mm files, and .m files; however, it seems that they're being ignored. I only see the .cpp and .h files. I added rules for those in the projectDef.make file, but it doesn't seem to make a difference: file (GLOB PLATFORM RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} Mac/[^.]*.cpp Mac/[^.]*.h Mac/[^.]*.m #added by me Mac/[^.]*.mm #added by me Mac/[^.]*.cmake ) Even if I add the files in manually, I get a series of compilation errors. There are about 20 of them, all related to the file NSObjRuntime.h file: Parse Issue - Expected unqualified-id Parse Issue - Unknown type name 'NSString' Semantic Issue - Use of undeclared identifier 'NSString' Parse Issue - Unknown type name 'NSString' ... ... Semantic Issue - Use of undeclared identifier 'aSelectorName' ... ... Semantic Issue - Use of undeclared identifier 'aClassName' ... It continues like this for some time with similar errors... From what I've read, these errors appear because of dependencies on the Foundation Framework, which I believe I've included in the project. I also tried clicking the project in XCode I'm to the point now where I'm not sure what to try next. People say it's not hard to use Objective C in C/C++ code, but being new to XCode and Objective C might contribute to my confusion. This is only day 4 for me in this new platform. What do I need to do to get XCode to compile the Objective C code? Please remember that I'm a little new to this, so I'd appreciate it if you leave detailed answers as opposed to the vague one-liners that are common in the firebreath tag. I'm just a little in over my head, but if you can get me past this hurdle I'm certain I'll be good to go from there. UPDATE: I edited projects/MyPlugin/CMakeLists.txt and added in the .m and .mm rules there too. after running prepmac.sh, the files are included in the project, but I still get the same compile errors. I moved all the .h files and .mm files from the Obj C code to the MyPlugin root folder and reran the prepmac.sh file. Problem still exists. Same compile errors.

• Cannot connect via HTTPS in Java app on MacOSX (Certificate validation issue)

  - by johnnyx

  I have a java application that connects to a webservice over https. The domain where i host the webservice has a valid Goddaddy issued SSL certificate. The application works fine on Windows but on MacOSx i receive the following exception when attempting to connect to the webservice via https. sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I've tested it on two machines running Mac OS X 10.7.2 with the latest java runtime updates. I understand this is usually a problem with self signed certificates that need to be added manually, but i have a valid Godaddy issued certificate. In webbrowsers (safari & firefox) on mac os the certificate is recognized and seems ok. I even tried adding the certificate to the key chain manually like in the gase of a self signed one but to no result.

• Mac OS X: Best way to do runtime check for retina display?

  - by Todd Ditchendorf

  Given a Cocoa application which runs on Mac OS X 10.7 and later: What is the best way to check, at runtime, if your app is currently running on a Mac with at least one retina display attached? If checking for this sort of thing is just really wrong-headed, I fully welcome a well-reasoned explanation of why. But I'd still like to know :). It seems likely you could just do a check specifically for the new Mac Book Pro "Retina" hardware (the only Mac at this time which currently has a retina display), but ideally, I'd really prefer a more general/generic/future-proof way to check than this. Ideally, I'd like to know how to detect the retina display, not the specific Mac model which currently happens to ship with a retina display.

• Rsync to a WebDAV filesystem on OSX copies all files regardless of being changed or not.

  - by MarceloR

  I am trying to sync my (Mac) desktop, with an iPad and an iPhone. OSX mounts WebDAV as a native filesystem, but syncing results in all files in my directory structure being copied again. This occurs when I use rsync -a or even a simple rsync -r. Various iPhone OS apps use the WebDAV server in iPhone OSX to transfer files. This occurs on several apps I use including GoodReader.

Last week, I had installed slapd on Ubuntu 11, and was able to authenticate against it from OS X Lion after finding the following blog post: Fixing OpenLDAP Authentication on OS X Lion This suggests running the following commands to fix the authentication problem /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string CRAM-MD5" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string NTLM" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist /usr/libexec/PlistBuddy -c "add ':module options:ldap:Denied SASL Methods:' string GSSAPI" /Library/Preferences/OpenDirectory/Configurations/LDAPv3/yourldapserver.plist However, I ran these commands on OS X Mountain Lion, and I am still unable to authenticate. I can't even use the Directory Editor app to examine the AD. I am however able to bind to the server via python-ldap's ldap.simple_bind_s('cn=admin,dc=foo,dc=net,'secret'). The error I am getting when trying to use Director Editor is Error Code (5000)

• Audio Midi Setup needs to be quit before able to be opened again in OS X Mountain Lion

  - by Dschee

  Since Mac OS X Lion (I'm using Mac OS 10.8.2 now) I have the exact same issue with audio midi setup software from Apple. It's not really a not working thing but it still is annoying: Every time I open audio midi setup to change something (e.g. change to my Apple TV for audio playback) and close the window afterwards the application doesn't quit – what would be OK if a click on the Icon (or the starting of the application over Spotlight) would cause the application to open a new window of audio midi setup, but it doesn't. So what I have to do to get the window back is first quitting the application manually and restarting it again. That's quite painful since I sometimes opened the application days ago and forgot that it's still opened... Does anyone have the same issue? Can someone explain this behavior to me? And most important: Does anyone know a workaround?

• Tuning OS X Virtual Memory

  - by dcolish

  I've noticed some really odd results form vm_stat on OSX 10.6. According to this, its barely hitting the cache. Searches of pretty much everywhere I could think of turn up little to explain why the rate is so low. I asked a few friends and they're seeing the same thing. What gives and how can I make it better?

• How to manage permissions on a shared volume for OSX and ubuntu

  - by gentmatt

  On my mac I'm using an unjournaled HFS partition to share files between OSX 10.8 and Ubuntu 12.04. It was a nice thought at first, because Time Machine will automatically backup the volume in OSX, but I soon noticed that OSX and Ubuntu mess with the permission in a way that makes things messy for me. So, in order to fully view and change files, I keep using chmod to apply permissions that which will allow me to fully use a document. But I don't understand why I have to keep applying changes over and over. Is possible to set some kind of permission permanently so that both operating systems will respect permanently? I guess 777 will work, but I thought that this is not a smart thing to do. But as long as 'others' does not get full access (third seven), I see a lock icon on the file in ubuntu.

• Can't find partition tab in disk utility osX ver. 10.6.8

  - by John W

  I just got a used Mac Book Pro. I created a new admin account and deleted the old one as well as one other user. This is an older late 2007 MBP... the osX upgrade to 10.6.8 was just performed. My Macintosh HD is showing up as Partition 2. I ran disk utility (not from install disk), but there was no partition tab. I have a 160GB drive with only 53GB of space left on it. Since I am the only user and have no files on the laptop yet, I don't understand why there is so little space left. Surely the OS can't use up over 100GB. I wanted to run disk utility to see if there were any recovery partitions or other partition left over from the previous owner that could be erased to make room for expanding the main partition. Unfortunately, there is no partition tab in disk utility. The documentation I have found on line states that this version of osX includes that utility. The osX disks I have are for an older version so I wasn't sure if they would be of any use in solving this problem. Also, I was afraid if using the disks, would I lose the little bit of data/apps that I have assembled. I would rather not do a fresh install and have to do all the updates again to achieve this. The previous owner had some apps that I don't want to lose as I would have to pay handsomely to get them back. Simply, if all the previous users data is backed up on here after deleting user is still taking up space on a recovery partition (that I can't see)... I need to locate it erase it and expand the primary partition to re-aquire disk space for my files. I am new to Mac, so please be as descriptive as possible. Thanks.
