  • Compiling Visual c++ programs from the command line and msvcr90.dll

    - by Stanley kelly
    Hi, When I compile my Visual c++ 2008 express program from inside the IDE and redistribute it on another computer, It starts up fine without any dll dependencies that I haven't accounted for. When I compile the same program from the visual c++ 2008 command line under the start menu and redistribute it to the other computer, it looks for msvcr90.dll at start-up. Here is how it is compiled from the command line cl /Fomain.obj /c main.cpp /nologo -O2 -DNDEBUG /MD /ID:(list of include directories) link /nologo /SUBSYSTEM:WINDOWS /ENTRY:mainCRTStartup /OUT:Build\myprogram.ex e /LIBPATH:D:\libs (list of libraries) and here is how the IDE builds it based on the relevant parts of the build log. /O2 /Oi /GL /I clude" /I (list of includes) /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /FD /EHsc /MD /Gy /Yu"stdafx.h" /Fp"Release\myprogram" /Fo"Release\\" /Fd"Release\vc90.pdb" /W3 /c /Zi /TP /wd4250 /vd2 Creating command line "cl.exe @d:\myprogram\Release\RSP00000118003188.rsp /nologo /errorReport:prompt" /OUT:"D:\myprgram\Release\myprgram.exe" /INCREMENTAL:NO /LIBPATH:"d:\gtkmm\lib" /MANIFEST /MANIFESTFILE:"Release\myprogam.exe.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"d:\myprogram\Release\myprogram.pdb" /SUBSYSTEM:WINDOWS /OPT:REF /OPT:ICF /LTCG /ENTRY:"mainCRTStartup" /DYNAMICBASE /NXCOMPAT /MACHINE:X86 (list of libraries) Creating command line "link.exe @d:\myprogram\Release\RSP00000218003188.rsp /NOLOGO /ERRORREPORT:PROMPT" /outputresource:"..\Release\myprogram.exe;#1" /manifest .\Release\myprogram.exe.intermediate.manifest Creating command line "mt.exe @d:\myprogram\Release\RSP00000318003188.rsp /nologo" I would like to be able to compile it from the command line and not have it look for such a late version of the runtime dll, like the version compiled from the IDE seems not to do. Both versions pass /MD to the compiler, so i am not sure what to do.

  • Extension methods in class library project

    - by Mostafa
    I've implemented some extension methods and put those in separate Class Library project. Imagine I have a simple extension method like this in class library called MD.Utility: namespace MD.Utility { public static class ExtenMethods { public static bool IsValidEmailAddress(this string s) { Regex regex = new Regex(@"^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$"); return regex.IsMatch(s); } } } But nowhere in WebApp like App_code folder or WebFroms code-behind page I can't use this Extension method. If I do like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using MD.Utility; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string email = "[email protected]"; if (email.IsValidEmailAddress()) { //To do } } } The compiler doesn't recognize IsValidEmailAddress() and even no intellisense support. While if I put my extension method in App_Code folder it's ok for using in another cs file in App_code Folder or Web Form code-behind pages.

  • why is a minus sign prepended to my biginteger?

And will the minus sign affect the hash result? because i am going to implement it to hash password stored on my database

  • My kernel only works in block (0,0)

    - by ZeroDivide
    I am trying to write a simple matrixMultiplication application that multiplies two square matrices using CUDA. I am having a problem where my kernel is only computing correctly in block (0,0) of the grid. This is my invocation code: dim3 dimBlock(4,4,1); dim3 dimGrid(4,4,1); //Launch the kernel; MatrixMulKernel<<<dimGrid,dimBlock>>>(Md,Nd,Pd,Width); This is my Kernel function __global__ void MatrixMulKernel(int* Md, int* Nd, int* Pd, int Width) { const int tx = threadIdx.x; const int ty = threadIdx.y; const int bx = blockIdx.x; const int by = blockIdx.y; const int row = (by * blockDim.y + ty); const int col = (bx * blockDim.x + tx); //Pvalue stores the Pd element that is computed by the thread int Pvalue = 0; for (int k = 0; k < Width; k++) { Pvalue += Md[row * Width + k] * Nd[k * Width + col]; } __syncthreads(); //Write the matrix to device memory each thread writes one element Pd[row * Width + col] = Pvalue; } I think the problem may have something to do with memory but I'm a bit lost. What should I do to make this code work across several blocks?

  • Linux boot on a raid1 software raid ?

    - by azera
    Hello I am trying to convert my single disk boot to a raid1 boot So far here is what i have: I sucessfully create the raid 1 as degraded with the new drive alone, I copied all the data on it I can mount that raid 1, see its files etc I already have a raid5 that is working on the same box (although not booting on it) I have installed grub on both drive When grub boot, it loads the kernel alright, but during the kernel boot it fails to load the "root block device" The kernel tells me : 1 - detected that root device is an md device 2 - determining root devices 3 - mounting root 4 - mounting /dev/md125 on /newroot failed: input/output error. Please enter another root device: ... At this point, if I enter /dev/sda3 (my "old" root device that isn't converted to raid yet) everything boots fine without the root. The /dev/md125 device is indeed created but it seems to be created after the error happens, as in it creates it after loading the device, when mdadm is loaded. Somehow it looks like it can't/doesn't load the raid array before it needs to mount it, and I don't know how I can solve that. My config files (taken from the system once it boots with sda3 as root device): $ cat /etc/mdadm.conf ARRAY /dev/md/md0-r5 metadata=0.90 UUID=1a118934:c831bdb3:64188b84:66721085 ARRAY /dev/md125 metadata=0.90 UUID=48ec4190:a80d4dde:64188b84:66721085 $ cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] [raid0] [raid10] md125 : active raid1 sdc3[1] 477853312 blocks [2/1] [_U] md127 : active raid5 sdd[0] sdf[3] sdb[2] sde[1] 4395415488 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] unused devices: <none> $ cat /boot/grub/menu.lst default 0 timeout 8 splashimage=(hd0,0)/boot/grub/splash.xpm.gz title Gentoo Linux 2.6.31-r10 root (hd0,0) #kernel /boot/kernel-genkernel-x86_64-2.6.31-gentoo-r10 root=/dev/ram0 real_root=/dev/sda3 kernel /boot/kernel-genkernel-x86_64-2.6.31-gentoo-r10 root=/dev/md125 md=125,/dev/sdc3,/dev/sda3 initrd /boot/initramfs-genkernel-x86_64-2.6.31-gentoo-r10 # blkid /dev/sda1: UUID="89fee223-b845-4e0a-8a0b-e6cf695d5bcf" TYPE="ext2" /dev/sda2: UUID="a72296a8-d7d4-447f-a34b-ee920fd1a767" TYPE="swap" /dev/sda3: UUID="97eb0a6a-c385-4a9d-bf74-c0bab1fa4dc1" TYPE="ext3" /dev/sdb: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sdc1: UUID="d36537fd-19a0-b8a3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sdd: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sde: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/md127: UUID="13a41589-4cf1-4c04-91ca-37484182c783" TYPE="ext4" /dev/sdf: UUID="1a118934-c831-bdb3-6418-8b8466721085" TYPE="linux_raid_member" /dev/sdc2: UUID="a1916397-1b48-45d7-9f98-73aa521e882f" TYPE="swap" /dev/sdc3: UUID="48ec4190-a80d-4dde-6418-8b8466721085" TYPE="linux_raid_member" /dev/md125: UUID="c947ed64-1d4d-4d1d-b4d2-24669fff916e" SEC_TYPE="ext2" TYPE="ext3" # mdadm -E mdadm: No devices to examine # fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe975e9fc Device Boot Start End Blocks Id System /dev/sda1 1 5 40131 83 Linux /dev/sda2 6 1311 10490445 82 Linux swap / Solaris /dev/sda3 1312 60801 477853425 83 Linux Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe975e9fc Device Boot Start End Blocks Id System /dev/sdc1 1 5 40131 83 Linux /dev/sdc2 6 1311 10490445 82 Linux swap / Solaris /dev/sdc3 1312 60801 477853425 83 Linux Disk /dev/md125: 489.3 GB, 489321791488 bytes 2 heads, 4 sectors/track, 119463328 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk identifier: 0x00000000 Disk /dev/md125 doesn't contain a valid partition table

  • Building NanoBSD inside a jail

    - by ptomli
    I'm trying to setup a jail to enable building a NanoBSD image. It's actually a jail on top of a NanoBSD install. The problem I have is that I'm unable to mount the md device in order to do the 'build image' part. Is it simply not possible to mount an md device inside a jail, or is there some other knob I need to twiddle? On the host /etc/rc.conf.local jail_enable="YES" jail_mount_enable="YES" jail_list="build" jail_set_hostname_allow="NO" jail_build_hostname="build.vm" jail_build_ip="192.168.0.100" jail_build_rootdir="/mnt/zpool0/jails/build/home" jail_build_devfs_enable="YES" jail_build_devfs_ruleset="devfsrules_jail_build" /etc/devfs.rules [devfsrules_jail_build=5] # nothing Inside the jail [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# sysctl security.jail security.jail.param.cpuset.id: 0 security.jail.param.host.hostid: 0 security.jail.param.host.hostuuid: 64 security.jail.param.host.domainname: 256 security.jail.param.host.hostname: 256 security.jail.param.children.max: 0 security.jail.param.children.cur: 0 security.jail.param.enforce_statfs: 0 security.jail.param.securelevel: 0 security.jail.param.path: 1024 security.jail.param.name: 256 security.jail.param.parent: 0 security.jail.param.jid: 0 security.jail.enforce_statfs: 1 security.jail.mount_allowed: 1 security.jail.chflags_allowed: 1 security.jail.allow_raw_sockets: 0 security.jail.sysvipc_allowed: 0 security.jail.socket_unixiproute_only: 1 security.jail.set_hostname_allowed: 0 security.jail.jail_max_af_ips: 255 security.jail.jailed: 1 [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# mdconfig -l md2 md0 md1 md0 and md1 are the ramdisks of the host. bsdlabel looks sensible [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# bsdlabel /dev/md2s1 # /dev/md2s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 1012016 16 4.2BSD 0 0 0 c: 1012032 0 unused 0 0 # "raw" part, don't edit newfs runs ok [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# newfs -U /dev/md2s1a /dev/md2s1a: 494.1MB (1012016 sectors) block size 16384, fragment size 2048 using 4 cylinder groups of 123.55MB, 7907 blks, 15872 inodes. with soft updates super-block backups (for fsck -b #) at: 160, 253184, 506208, 759232 mount fails [root@build /usr/obj/nanobsd.PROLIANT_MICROSERVER]# mount /dev/md2s1a _.mnt/ mount: /dev/md2s1a : Operation not permitted UPDATE: One of my colleagues pointed out There are some file systems types that can't be securely mounted within a jail no matter what, like UFS, MSDOFS, EXTFS, XFS, REISERFS, NTFS, etc. because the user mounting it has access to raw storage and can corrupt it in a way that it will panic entire system. From http://www.mail-archive.com/[email protected]/msg160389.html So it seems that the standard nanobsd.sh won't run inside a jail while it uses the md device to build the image. One potential solution I'll try is to chroot from the host into the build jail, rather than jexec a shell.

  • How to get an inactive RAID device working again?

    - by Jonik
    After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

  • How do I tell mdadm to start using a missing disk in my RAID5 array again?

    - by Jon Cage
    I have a 3-disk RAID array running in my Ubuntu server. This has been running flawlessly for over a year but I was recently forced to strip, move and rebuild the machine. When I had it all back together and ran up Ubuntu, I had some problems with disks not being detected. A couple of reboots later and I'd solved that issue. The problem now is that the 3-disk array is showing up as degraded every time I boot up. For some reason it seems that Ubuntu has made a new array and added the missing disk to it. I've tried stopping the new 1-disk array and adding the missing disk, but I'm struggling. On startup I get this: root@uberserver:~# cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d1 : inactive sdf1[2](S) 1953511936 blocks md0 : active raid5 sdg1[2] sdc1[3] sdb1[1] sdh1[0] 2930279808 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] I have two RAID arrays and the one that normally pops up as md1 isn't appearing. I read somewhere that calling mdadm --assemble --scan would re-assemble the missing array so I've tried first stopping the existing array that ubuntu started: root@uberserver:~# mdadm --stop /dev/md_d1 mdadm: stopped /dev/md_d1 ...and then tried to tell ubuntu to pick the disks up again: root@uberserver:~# mdadm --assemble --scan mdadm: /dev/md/1 has been started with 2 drives (out of 3). So that's started md1 again but it's not picking up the disk from md_d1: root@uberserver:~# cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md1 : active raid5 sde1[1] sdf1[2] 3907023872 blocks level 5, 64k chunk, algorithm 2 [3/2] [_UU] md_d1 : inactive sdd1[0](S) 1953511936 blocks md0 : active raid5 sdg1[2] sdc1[3] sdb1[1] sdh1[0] 2930279808 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] What's going wrong here? Why is Ubuntu trying to pick up sdd into a different array? How do I get that missing disk back home again? [Edit] - After adding the md1 to mdadm.conf it now tries to mount the array on startup but it's still missing the disk. If I tell it to try and assemble automatically I get the impression it know it needs sdd but can't use it: root@uberserver:~# mdadm --assemble --scan /dev/md1: File exists mdadm: /dev/md/1 already active, cannot restart it! mdadm: /dev/md/1 needed for /dev/sdd1... What am I missing?

  • LVM, Soft RAID1, and Replication?

    - by mtkoan
    Hi all, I am practicing putting together a HA file server. It is a linux server with 2 1.5TB Hard drives. My plan is to use LVM to manage the physical volumes into logical volumes for /, /home, and /var. Then use md (soft RAID 1) to mirror the image onto the second HDD, THEN use DRDB to mirror the entire setup another server. Is this overkill? Would I just be okay with just md and DRDB? The system will serve user's homedirs (~100) and probably some groupware or other local intranet. On my own machines I've always separated root and /home partitions in case I break something, I can easily reinstall the OS. Should I follow that same theory here? If so I need LVM, because I really can't predict where we'll need more space, /var or /home.

  • Tracking the linux config with git: how?

    - by Pierre
    I'd like to track my linux configurations with git. My idea is to have a branch for each server. /etc is not the only one directory to be tracked (I won't git init in '/etc' ) As far as I could see, it is possible to init a git for a distant directory. I tried this: # mkdir -p /git/.git # cd /git # git --work-tree=/ --git-dir=/git/.git init Initialized empty Git repository in /git/.git/ 1) Creating a new branch before everything is not possible # git branch server1 fatal: Not a valid object name: 'HEAD'. 2) adding a file in master/HEAD is not possible # touch README.md # git add README.md fatal: Unable to create '//.git/index.lock': No such file or directory how should I properly setup git to track my system-config ? Thanks. P.

  • Emacs: Changing the location of auto-save files

    - by Dominic Rodger
    I've currently got: (setq backup-directory-alist `((".*" . ,temporary-file-directory))) (setq auto-save-file-name-transforms `((".*" ,temporary-file-directory t))) in my .emacs, but that doesn't seem to have changed where auto-save files get saved (it has changed where backup files get saved. M-x describe-variable shows that temporary-file-directory is set to /tmp/, but when I edit a file called testing.md and have unsaved changes, I get a file called .#testing.md in the same directory. How can I make that file go somewhere else (e.g. /tmp/)? I've had no luck with these suggestions, so any suggestions welcome! If it helps, I'm on GNU Emacs 23.3.1, running Ubuntu.

  • What exactly is the "Multi-threaded Debug DLL" Runtime Library option doing in VS 2008?

    - by GregH
    I have a solution in VS 2008 that creates a DLL. I then use that DLL in another application. If I go in to the DLL projects property pages and change the following configuration for a DEBUG build then the built dll no long provides the desired functionality. If I change it back and rebuild the DLL, then the DLL does provide the correct functionality: Property Pages = Configuration Properties = C/C++ = Code Generation = Runtime Library If set to "Multi-threaded Debug DLL (/MDd)" then everything works as it should. I get the correct functionality from the DLL If set to "Multi-threaded DLL (/MD)" then the DLL does not function properly...no runtime errors or anything, it just doesn't work (The DLL is supposed to plot some lines on a map but does not in this mode). So the question is, why does using the /MDd flag result in correction functionality of the underlying code, while /MD results in incorrect functionality? A little background...somebody else developed the DLL in C++ and I am using this DLL in a VB.net application.
