Linking Boost libs required by ASIO on Windows giving undefined reference errors



  • I am trying to use a boost/asio. For simplicity, I have one main.cpp as below that includes boost/asio.hpp

    @
    #include <boost/asio.hpp>

    int main(int argc, char *argv[])
    {
    return 0;
    }
    @

    my .pro file looks like this

    @
    QT += core gui

    CONFIG += console

    TARGET = SIDController
    TEMPLATE = app

    INCLUDEPATH += $$PWD/../../../libs/boost_1_44

    SOURCES += main.cpp

    win32: LIBS += -L$$PWD/../../../libs/boost_1_44/stage/lib/ -llibboost_filesystem-vc100-mt -llibboost_system-vc100-mt

    INCLUDEPATH += $$PWD/../../../libs/boost_1_44/stage/lib
    DEPENDPATH += $$PWD/../../../libs/boost_1_44/stage/lib

    win32: PRE_TARGETDEPS += $$PWD/../../../libs/boost_1_44/stage/lib/libboost_system-vc100-mt.lib
    @

    When I compile I get these errors

    When I Google these error, it looks like these are errors you get when boost_system and boost_filesystem are not linked correctly, but I'm pretty sure I'm setting it up properly in the .pro file. I tried all sorts of variations on LIBS +=. I used every flavor of boost_system and boost_filesystem, including mt, s, with the -1_44 at the end, without it. I built boost using "build-type=complete" and used every variation that that produced.

    Arg, I'm completely stuck and cannot continue my project until I can figure this out. It really doesn't make any sense why these files are not linking properly. Please can anyone help.



  • Ping? This is really a deal breaker for Qt. I really need a way to link those libraries correctly. I've poured through the qmake documentation and can't find anything new that might help me. I don't usually post to forums unless I get really desperate. So help! :)


  • Moderators

    While we all appreciate the urgency you feel for your problem, please don't badger everyone for help. Especially after less than an hour and a half. Doing so is very rude and, if anything, will hinder your chances of getting effective and timely help.

    If anyone has useful input regarding your problem, they will post. Be patient.



  • Noted. I'll be patient.



  • Your compilation log does not fit with your example: in your log, your linker tries to link
    @main.o mainwindow.o voiceview.o serialsid.o moc_mainwindow.o moc_voiceview.o@
    In your .pro file, you have only one file, without preprocessing (moc)

    After a bit of googling, (stackoverflow), seems to be a common problem, even without using Qt... Did you manage to link something without Qt already with boost ? From what I've read, you're doing it right.



  • You are correct. Excuse the misleading compile output. I was trying to say that the important part of the output was the reference errors. Here is a more appropriate output generated from the exact example above.

    The problem remains. I am unable to successfully link boost_system and boost_filesystem. Thanks for pointing that out.



  • Another string which looks damn strange : you're compiling Qt with mingwin whereas you compiled boost with visual 10 (vc100 in library name).
    Msvc and mingwin have different ABIs and can't be linekd together.
    Either compile your Qt with Visual 2010 (you'll have to do it yourself) or compile boost with mingwin



  • Hi golgobot,

    In my opinion "this article":http://www.richelbilderbeek.nl/CppLinkErrorUndefinedReferenceToBoostSystemGet_system_categoryQtCreator.htm might be useful in your case. The suggested solution is to add the following line to your .pro file:

    @LIBS += -lboost_system@

    Cheers,
    Leon



  • Leon:

  • oh, true... It always confuse me between visual and gcc, which sometime truncate names differently. At least, trying is cheap !



  • Thanks everyone. I started building boost using mingw before I went to work today. It should be done when I get home. I'll try that out and see if that works!

    One last thing. Does anyone know the difference between libboost_system and boost_system? Is one static and the other dynamic?



  • some linkers (especially gnu) removes lib at the beginning of file and extension (.a usually). This tradition comes from unix world, it's not followed extensively in windows world (I don't think msvc acts like that). Basically, using gnu ld (thus mingwin), to link a lib named libtoto.a, you would use -ltoto

    This is a "qmake specific feature":http://doc.qt.nokia.com/latest/qmake-project-files.html#declaring-qt-libraries The familiar Unix-style notation for specifying libraries and paths can be used.

    [/quote]

    Excellent example :)



  • Ok so I rebuild boost libraries using mingw. From my boost root I ran the command

    @
    bjam.exe --toolset=gcc --build-type=complete
    @

    This rebuilt the boost libraries using mingw. I ended up with a lot of libraries with ".a" extensions, the most important of which are libboost_system-mgw44-mt-1_44.a and libboost_filesystem-mgw44-mt-1_44.a. These are the two I want to link. My lib-includes in my .pro file looks like this below (the rest is the same as above)

    @
    win32: LIBS += -L$$PWD/../../../libs/boost_1_44/stage/lib/ -lboost_system-mgw44-mt-1_44 -lboost_filesystem-mgw44-mt-1_44

    INCLUDEPATH += $$PWD/../../../libs/boost_1_44/stage/lib
    DEPENDPATH += $$PWD/../../../libs/boost_1_44/stage/lib
    @

    the "lib" prefix is omitted, which is standard for including gcc libs.

    When I compile I get the exact same error

    bq.

    collect2: ld returned 1 exit status

    After some more searching online I found a "post":http://stackoverflow.com/questions/1814548/boostsystem-category-defined-but-not-used that suggested I put this define statement

    @
    #ifndef BOOST_SYSTEM_NO_DEPRECATED
    #define BOOST_SYSTEM_NO_DEPRECATED 1
    #endif
    @

    Before my include. I ran the build and now I get only one error (and lots of warnings, but let's ignore those for now)

    bq.
    ......\libs\boost_1_44/boost/asio/error.hpp: In function 'const boost::system::error_category& boost::asio::error::get_system_category()':
    ......\libs\boost_1_44/boost/asio/error.hpp:220: error: 'get_system_category' is not a member of 'boost::system'

    I tried Googling that error, but came up with nothing. So I don't really feel closer to a solution. Just more confused than ever before. I look forward to seeing if anyone can help solve this mystery :)



  • I also feel like I should have to be placing hacky #defines throughout my code to get it to link properly.



  • The linker is sensitive to the order in which you link : you must link file_system, then system. Basically, file_system relies on system, this latter must appear after on the command line.

    Could you please paste the exact command line that make is running ? Seems strange that it doesn't work...



  • The actual command that it is running is

    bq. g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -Wl,-s -Wl,-subsystem,console -mthreads -Wl -o release\SIDController.exe release/main.o -L"c:\Qt\2010.05\qt\lib" -LC:/workspaces/qt/SIDController/../../../libs/boost_1_44/stage/lib/ -lboost_filesystem-mgw44-mt-1_44 -lboost_system-mgw44-mt-1_44 -lQtGui4 -lQtCore4

    It seems to be including the libraries for linking. I also switched the order of the libraries so boost_filesystem was first



  • And here is the complete output after a clean, then rebuild. Presented in two parts cause the max char limit for a post is 6000. This is easily reproducible using main.cpp shown at the beginning of the post in Windows 7 on a 64 bit processor. Could there be a 32 vs 64 bit issue?

  • Ok I got it to compile, but it's not pretty at all.

    Firstly, I added the preprocessor definition mentioned above and documented "here":http://www.boost.org/doc/libs/1_44_0/libs/system/doc/reference.html to my .pro file, plus I also had to add a windows library called ws2_32, so my new .pro file looks like this (ignore how it's not cross platform)

    @
    DEFINES += BOOST_SYSTEM_NO_DEPRECATED

    win32: LIBS += -L$$PWD/../../../libs/boost_1_44/stage/lib/ -lboost_filesystem-mgw44-mt-1_44 -lboost_system-mgw44-mt-1_44 -lws2_32
    @

    After all that I was getting one more error

    bq.
    error.hpp:220: error: 'get_system_category' is not a member of 'boost::system'

    So I just commented that line out like so

    @
    inline const boost::system::error_category& get_system_category()
    {
    //return boost::system::get_system_category();
    }
    @

    At least it compiles. I have no idea if it runs yet or how important that line of code is. That method is defined inside an "#ifndef BOOST_SYSTEM_NO_DEPRECATED", so I don't know why that function uses a method that can potentially by ifdef'ed out.

    I'm used to running in Visual Studio where all this stuff just work.

    If anyone has a better way, PLEASE, let me know! Thanks for everyone's help so far.


  • Moderators

    bq. So I just commented that line out... At least it compiles.

    I don't want this to devolve into a discussion of how to debug and patch boost, but from a general coding standpoint this doesn't seem like a very good idea at all. You now have a method that has no return value at all. While it may compile, it's just setting the stage for an unknown bug to pop up down the line if the get_system_category() method should be called somewhere down the line. At the very least, if you do go this route, you might consider putting some sort of warning debug message in that method and returning some known default value.



  • I know this is a very old post, but just for reference in case someone needs it in the future, the best way to get ASIO working with Qt is using it by itself instead of using the Boost integrated version.

    Asio is a project on its own, and it doesn't need the Boost dependency in case you need to use it in something else (like Qt). Here's the project link in case someone needs it: "Think Async ASIO":http://think-async.com

    I had a lot of issues until I was able to just get rid of Boost, which has things that I can already do with Qt, and in a much easier and cleaner way.

    Thanks



  • Thanks a lot, i really helped me and save coutless hours of research!!!

    EDIT 1 :

    Hi,

    In case you are doing Ogre3D (OGRE 1.8.1 SDK for Visual C++ .Net 2010 (32-bit) ) then use QT5 32bit instead of the QT5 64bit version, it will pass.

    I think it has been compiled (boost included) with 32bit thus i suppose i have to take src and recompile (using my 64bit) but thats another story where i wont go for now since OGRE 1.9 RC 1 SDK for Visual C++ .Net 2012 (64-bit) will be soon release on stable version.

    Regards

    EDIT 2 :

    Downloaded Qt libraries 4.8.4 for Windows and configured my QT creator (the one coming with full QT5 and guess what .... Ogre3D is working like a charm when compiling on 4.8.4.
