  • Error in value of default parameter [Bug in Visual C++ 2008?]

    - by HellBoy
    I am facing following issue while trying to use template in my code I have some C++ code which i call from C functions. Problem is I am getting different values in the following code for statement 1 and 2. Type id : unsigned int statement 1 : 4 statement 2 : 1 C++ Code : template <typename T> void func(T* value, unsigned int len = sizeof(T)) { cout << "Type id : " << typeid(T).name() << endl; cout << "statement 1 " << sizeof(T) << endl; cout << "statement 2 " << len << endl; } template <typename T> void func1(T data) { T val = data; func(&val); } C Code : void test(void *ptr, unsigned int len) { switch(len) { case 1: func1(*(static_cast<uint32_t *>(ptr)) break; } } This happens only on windows. On Linux it works fine.

  • OS Development. Only Few Particular Questions

    - by Total Anime Immersion
    I am new to this site as a member but have consulted its answers quite a lot of times. Besides my questions regarding OS Development hasn't been answered in any forum. In OS Dev. we make a bootloader. The org point is 7C00H. Why so? Why not 0000h? What are the last two signatures in the bootloader used for? People on every forum have answered that it is important for the system to recognize it as a bootable media. But I want a specific answer. What do each of those signatures do. I have the basic concept of a kernel. Point is.. it relates to different files required in a system. It sort of binds up everything that is individually developed. Now the thing is that that I have floating ideas in my mind regarding different aspects like keyboard, mouse, etc.. how do I put them all together? Which should I start with first? If possible please provide a step by step procedure of the startups of the kernel. Suppose I have developed my language entirely in C and Assembly. Now questions is will exe files work on my system.. if it doesn't then I have to create my own files and publish them. Which is a bad idea.. next step would be for me to go for a compiler for a language which I have designed myself. Now the point is.. How do I implement the compiler into my OS? After all this my final question is that.. How do you go about multitasking and multithreading? and I don't want to use int 21h as its dos specific.. how do I go about making files, renaming them, etc. and all assembly books teach 16 but programming.. how do i go about doing 32 bit or 64 bit with the knowledge I have.. if the basics and instructions are the same.. I don't mind.. but how do i go about otherwise? Don't tell me to give up the idea because I WON'T. And don't tell me it's too complex because I have a sharp knowledge of working of a system, C, Java, Assembly, C++ and python, C#, visual basic.. and not just basics but full fledged api developments.. but I really want to go deep into the systems part.. so I want professional help.. And I have gone through many OS project files but I want help particularly from this site as there are people with knowledge depth who can guide me the right way. And please don't suggest any books above 20$ and they should be available on flipkart as amazon charges massively for shipping and I prefer free shipping from flipkart.

  • how to install g77 on ubuntu 12.04

    - by ubuntu-beginner
    I want a workin g77 compiler on my Ubuntu 12.04 64 bit laptop. so did the following: 1. I change the sources.list by adding the following lines: deb http...hu.archive.ubuntu.com/ubuntu/ hardy universe deb-src ..//hu.archive.ubuntu.com/ubuntu/ hardy universe deb http:...hu.archive.ubuntu.com/ubuntu/ hardy-updates universe deb-src ..//hu.archive.ubuntu.com/ubuntu/ hardy-updates universe then I on a terminal i did the following: sudo apt-get update sudo apt-get install g77 Things looked very nice then. But when I tried to compile with g77 on my Fortran77 program. I got the following errors: /usr/bin/ld: cannot find crt1.o: No such file or directory /usr/bin/ld: cannot find crti.o: No such file or directory /usr/bin/ld: cannot find -lgcc_s collect2: ld returned 1 exit status Why doesn't the g77 work properly. Many people need g77 why cannot Ubuntu offer a workable g77 ? Please Help me ! Thanks from a ubuntu-beginner

  • Converting ANTLR AST to Java bytecode using ASM

    - by Nick
    I am currently trying to write my own compiler, targeting the JVM. I have completed the parsing step using Java classes generated by ANTLR, and have an AST of the source code to work from (An ANTLR "CommonTree", specifically). I am using ASM to simplify the generating of the bytecode. Could anyone give a broad overview of how to convert this AST to bytecode? My current strategy is to explore down the tree, generating different code depending on the current node (using "Tree.getType()"). The problem is that I can only recognise tokens from my lexer this way, rather than more complex patterns from the parser. Is there something I am missing, or am I simply approaching this wrong? Thanks in advance :)

  • Why does Facebook convert PHP code to C++?

    - by user72245
    I read that Facebook started out in PHP, and then to gain speed, they now compile PHP as C++ code. If that's the case why don't they: Just program in c++? Surely there must be SOME errors/bugs when hitting a magic compiler button that ports PHP to c++ code , right? If this impressive converter works so nicely, why stick to PHP at all? Why not use something like Ruby or Python? Note -- I picked these two at random, but mostly because nearly everyone says coding in those languages is a "joy". So why not develop in a super great language and then hit the magic c++ compile button?

  • How compilers know about other classes and their properties?

    - by OnResolve
    I'm writing my first programming language that is object orientated and so far so good with create a single 'class'. But, let's say I want to have to classes, say ClassA and ClassB. Provided these two have nothing to do with each other then all is good. However, say ClassA creates a ClassB--this poses 2 related questions: -How would the compiler know when compiling ClassA that ClassB even exists, and, if it does, how does it know it's properties? My thoughts thus far had been: instead of compiling each class at a time (i.e scan, parse and generate code) each "file (not really file, per se, but a "class") do I need to scan + parse each first, then generate code for all?

  • 'Bug in Mailman version 2.1.12'

    - by davorg
    I'm working on setting up a server running Plesk 10.4.4 Update #13 on Centos 6.2. I've configured Mailman and now I want to set up some mailing lists. I've created a list in the Plesk control panel, but when I try to administer the new list (by visiting http://lists.[domain].com/mailman/admin/[listname] I see the following error: Bug in Mailman version 2.1.12 We're sorry, we hit a bug! Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs. I see exactly the same error if I try to go to the list info page at http://lists.[domain].com/mailman/listinfo/[listname]. I would follow the instructions and look in the error logs, but I can't find them. I would expect to find a file at /var/log/mailman/error, but there's nothing there. My test list seems to work correctly. It sends all the expected email. It's just the web pages for the list that seem to be broken. Has anyone else seen this? Any suggestions for tracking down and fixing the problem? p.s. I think I've chosen the correct Stack Exchange site, but it this question would be better asked elsewhere, please let me know. Update: I got to the bottom of this, so I'm documenting the answer in case anyone else has the same problem. The fact that I couldn't find the error log was the clue. The problem was that the Mailman process didn't have permissions to create an error log. And it seems that if Mailman can't create an error log then it will respond to any web request with this error page. Creating an error log file (in /var/log/mailman/error) and giving it the correct permissions fixed the problem.

  • Ubuntu on VPS becomes unresponsive: BUG: soft lockup - CPU#0 stuck for 22s

    - by Bhante Nandiya
    We have a VPS running Ubuntu, on Xen. The problem is this, about once a day, for about 20-50 minutes, at a random time, the server becomes completely unresponsive to the outside world. After this period, it becomes responsive again, as if nothing had happened, it doesn't lose uptime, it doesn't restart. It just starts responding again as if it had been in suspended animation. These outages occur under conditions of non-exceptional memory and cpu, for example 70% mem, 5% cpu. I have stopped all non-essential services so the usage is very even. These outages don't particularly occur during times of increased memory/cpu (during daily tasks), they sometimes occur at times of very low cpu use (<2%), but in the past also occured during swapping. These blackouts have been occurring both under Ubuntu 12.04 LTS, and Ubuntu 14.04 LTS - no change at all (I upgraded Ubuntu specifically to see if it helped this problem). It is possible to log into our webhosts site, and use their administration console to see error messages from during this time. Presumably, these messages are from the Xen virtualization, the main message goes like this: BUG: soft lockp - CPU#0 stuck for 22s! [ksoftireqd/0:3] (repeats many times) SysRq : Emergency Sync (Sometimes this is the only message in the console) Others seen previously under different load situations include: BUG: soft lockup - CPU#0 stuck for 22s! [swapper/0:0] (repeated many times) or: INFO: rcu_sched detected stall on CPU 0 (t=15000 jiffies) (repeated many times with t getting bigger) From googling around I've tried various kernel parameters such as nohz=off and acpi=off to no avail. All tech support has said is that other Ubuntu installations are not suffering the same problem. Anyone got any ideas or experience with this problem?

  • How to create issue dependencies/links in Jira (3.13) ?

    - by zarko.susnjar
    Hi, We recently switched from other bug tracking software to Jira (3.13 currently ). We need to set issue linking in a manner that my task start time depends on other colleague's issue and I can not start until he resolves his issue... I goolged and found that this kind of thing is integrated in newer versions :/ Maybe we need some plugin, make some custom field, enable something in administration part... Any help would be appreciated... (please retag/add jira and bug-tracking tags or whatever)

  • XmlHttpRequest bug?

    - by valdo
    Hello all. I'm writing a program that among other things needs to download a file given its URL. I'm too lazy to implement the Http/Https protocols manually, so that I needed some library/object/function that'll do the job. Critical requirement: The download must be asynchronous. That is, the thread that issued the download must be able to do something else "while" downloading the file, plus the download must be able to be aborted anytime without any barbaric side effects (such as internal call to TerminateThread). Nice-to-have requirements: Should be able to download the file "into memory". Means - read the contents of the file as they arrive, not necessarily save it into some "file system" file. It'd be nice to have some convenient Win32 progress notification mechanism (waitable event, semahpore, completion port, etc.), rather than just periodically polling the download status. I've chosen the XmlHttpRequest COM object to do the work. It seemed to work fine enough, plus it supported asynchronous mode. However I noticed that after some period it just stops working. That is, after several successful file downloads it stops downloading anything. I periodically poll it to get its status, it reports "in-progress", but nothing actually happens, and there's no network activity. Moreover, when the same process creates another instance of XmlHttpRequest object to perform new downloads - the effect is the same. The object reports "in progress", whereas it doesn't even try to connect to the server (according to network sniffers and system TCP state). The only way to make this object work back is to restart the process. This makes me suspect that there's a sort of a bug (sorry, I meant undocumented feature) in the object. Also it's not a bug at the level of an individual object, since the problem persists when the object is destroyed and another one is created. It's probably some global state of the DLL that implements this object. Does anyone know something about this? Is this a known bug? I'm pretty sure there's no chance that I have another bug in my code, because of which it seems to me to be the bug is in the XmlHttpRequest. I've done enoughtests and spent time with the debugger to conclude without reasonable doubt that it's just the object stops working. BTW, while the object should work, I do all the waiting via MsgWaitXXXX API calls. So that if this object needs the message loop to work properly (for instance, it may create a hidden notification window and bind it to a socket via WSAAsyncSelect) - I give it the opportunity.

  • Ubuntu 11.10 - How can i stop self-feedback-loop, coming directly from my microphone to speaker?

    - by YumYumYum
    I have microphone audio, which comes instantly to my speaker. I am using default pulseaudio and alsa from the package. I have tried to setup: 1) PA /etc/pulse/default.pa /etc/asound.conf $ ls analog-input-aux.conf analog-input-fm.conf analog-input-mic.conf analog-input-tvtuner.conf analog-output-desktop-speaker.conf analog-output-mono.conf analog-input.conf analog-input-front-mic.conf analog-input-mic.conf.common analog-input-video.conf analog-output-headphones-2.conf analog-output-speaker.conf analog-input.conf.common analog-input-internal-mic.conf analog-input-mic-line.conf analog-output.conf analog-output-headphones.conf iec958-stereo-output.conf analog-input-dock-mic.conf analog-input-linein.conf analog-input-rear-mic.conf analog-output.conf.common analog-output-lfe-on-mono.conf 2) ALSA in lsmod to make sure no loopback modules are loaded etc but none is resolving it. And there are many less information available on this. Has anyone similar problem solution in Ubuntu 11.10? (this problem i have resolved in Ubuntu 11.04 by replacing the default pulseaudio version to latest source from git, but while trying the same in Ubuntu 11.10 does not worked). Any tips please?

  • $TERM set to "dumb" causes problems with suspend

    - by julkiewicz
    I've just upgraded from 11.04 to 11.10. So far I love it, everything seems just so much snappier. Now I just have one minor issue. When I try to suspend my laptop, it doesn't work - instead it fades out the screen, blocks it and then instantly wakes back. I've checked the logs in /var/log/pm-suspend.log and this fragment seems relevant: /usr/lib/pm-utils/sleep.d/000kernel-change suspend suspend: success. Running hook /usr/lib/pm-utils/sleep.d/00clear suspend suspend: TERM environment variable not set. /usr/lib/pm-utils/sleep.d/00clear suspend suspend: Returned exit code 1. Sat Nov 19 12:23:20 CET 2011: Inhibit found, will not perform suspend Sat Nov 19 12:23:20 CET 2011: Running hooks for resume The mentioned script at /usr/lib/pm-utils/sleep.d/00clear reads: #!/bin/bash clear When I open a terminal anywhere by hand, $TERM is set to either "linux" or "xterm". However somehow when the 00clear command is executed $TERM is set to "dumb". Two questions: What is the correct value for $TERM when running 00clear script? Where can I set it up? I've looked for solutions on the web, however I could only find information on how to configure $TERM in a regular terminal (and this one is set properly).

  • Should programmers itemize testing for projects? [on hold]

    - by Patton77
    I recently hired a programming team to do a port of my iPad app to the iPhone and Android platforms. Now, in a separate contract, I am asking them to implement a bunch of tips on how to play the app, similar like you would find in Candy Crush or Cut the Rope. They want to charge 12 hours @ $35/hr for the "Testing all of the Tips", telling me that normally it would take them more than 25 hours but that they will 'bear the difference'. I am not familiar with this level of itemization, but maybe it's a new practice? I am used to devs doing their own quality control, and then having a testing/acceptance period. They are using Cocos 2D-X, and they say that the tips going to multiple platforms makes all of the hours jack up. I feel like they might be overcharging, and it's difficult for me to know because it's kind of like with a mechanic. "It took us 5 hours to replace the radiator". How can you dispute that? It seems to me that most of you would charge for the work but NOT for hours that you are 'testing'. Am I missing something? Thanks for any help and advice you can give!

  • Oneiric desktop looks seriously defect after updates

    - by Matthijs
    Probably a coincidence, but after applying the fix to How to get the proper LightDM theme? and running the latest batch of updates, my desktop suddenly looked like this after rebooting: Funny thing is, it seems to be account specific, as my girlfriend's account seems unaffected. I can't logout because the whole entry is missing on the top right. Rebooting doesn't solve the issue. System settings (when run from the launcher) lacks a whole lot of icons and changeing the theme doesn't solve the problem (only changes the window top bar). I'm going to try the solution in How do I fix my theme? first, but if that doesn't work (likely, since I seem to have a slightly bigger problem than the one in that question) I'd love something else to try (other than creating a new account).

  • How to manage an issue tracker's backlog

    - by Josh Kelley
    We've been dutifully using Trac for several years now, and our "active tickets" list has grown to almost 200 items. These include bugs that are too low priority and too complicated to fix for now, feature requests that have been deferred, issues that have never really generated complaints but everyone agrees ought to be fixed someday, planned code refactorings and other design infelicities that we don't want to lose track of, etc. As a result, with almost 200 of these issues, the list is almost overwhelming; it's no longer useful as a source of what needs to be worked on right now. What's the best way to keep track of issues of this sort? Part of the problem is that some of these issues are such a low priority that they may never get done. I hate to lose track of these items (similar to not wanting to throw something out of my house in case I might need it someday); do I need to throw them out regardless (by marking them as wontfix) and assume I can find them in the future if I ever do need them?

  • Packard Bell Easynote NJ65 not saving gamma Setup.

    - by Pablo Gomez
    Hi. There seems to be a issue with the Easynote range of PB laptops. Since Ubuntu 10.10 does not use a Xorg.conf file to save your gamma / resolution /brightness setting, everytime I turn on my laptop I have to open up a terminal window and use the x-gamma command to set it up to my personal preference. Is there a way to create a configuration file which can save that into the system everytime I load up the OS? When I used to have a Compaq Presario (an F564LA with integrated nVIDIA graphics), I could save a config. file into the system which loaded up everything on startup To those who don't know the spec's for a NJ65 laptop, I'll provide them Processor: Intel® Pentium Dual Core @ 2.2 GHZ Video: Integrated Intel® GMA 4500MHD graphics HDD: 320GB SATA RAM: 2GB DDR2

  • Why does update-notifier contains system-crash-notification?

    - by int_ua
    I just had "System Program Problem Detected" window appearing several times before user session even started (I have KDM with autologin to locked session). I traced it with xprop to being /usr/lib/update-notifier/system-crash-notification which is binary (while I expected it to be some script) and belongs to update-notifier package (while I expected it to be somewhere from apport*). P.S. Clicking on Report problem... button didn't do anything. $ dpkg -s update-notifier | grep Version Version: 0.147 $ dpkg -L update-notifier | grep system-crash /usr/lib/update-notifier/system-crash-notification $ grep RELEASE /etc/lsb-release DISTRIB_RELEASE=13.10

  • Understanding the problem when things break in production

    - by bitcycle
    Scenario: You push to production The push broke multiple things That same build did not break qa or dev As a developer, you don't have prod access. There is lots of pressure from above to get things working agian. Specifics: PHP/MVC application that is API-driven in Zend. Deployed to a few servers. My question: While investigating, lets say I have a hunch that something is wrong. But, I don't know for sure. And, of course, I can't test things in production. If I have a suggested fix based on that hunch, would it be wise to try and apply it and see if it works, before understanding what the problem is?
