I am working on a project which needs to be executed in a Linux machine that has turned out not to have the GLIBCXX_3.4.20 version of a library, but the code needs it. Is there anyway to find which part of my code (C++) asks for this version?
I read the ELF file using objdump and realdef and I found which symbol needs it:
_ZSt24__throw_out_of_rang#GLIBCXX_3.4.20 (4)
but I don't know to which part of my code can be related.
Your question is essentially a duplicate of this question.
Except in your case, it's not libc.so.6, but libstdc++.so that's giving you trouble.
Your problem is that you are compiling with new GCC, but are running on a machine with an old libstdc++.so.
You have a few options:
you can update target machine to have a new enough libstdc++.so
you can build using older version of GCC
you could use -static-libstdc++ flag to link required version of libstdc++ directly into your application. This will make a larger binary, but it will not be using libstdc++.so at all.
Note that if you link against other shared libraries that do link against libstdc++.so, your binary may not run correctly on the target machine, so this solution should be used with caution.

I found many articles about the what I am about to ask but no precise answer. I wanted to compile a main file from a RSA library. However, this error appears and I don't know how to fix it:
The error in the image indicates that there's no such file or directory as ${workspaceFolder}boost/multiprecision/cpp_int.hpp.
The file boost/multiprecision/cpp_int.hpp is part of the Boost C++ Libraries. If Boost is not installed, as indicated in the comments above, it will be necessary to install Boost to provide the missing file and any related software to which it refers.
For information on installing Boost, take a look at the Boost Getting Started page.
Note that if you are using Linux, Boost is likely available in your system's repository (i.e. package manager, software manager, or whatever it's called on your system). If so, installing from there would probably be the easiest way to go.
If Boost did happen to be installed and the error was occuring, it would then be necessary to add the location of the Boost include files to the compilation command.
I get a project that was built for x86, and I am trying to make it work with mips. But I encounter problem when modifying the CMakelists.txt.
So here is the problem, the following code always use my PC's x86 library:
PKG_CHECK_MODULES(LIBCRYPTO REQUIRED libcrypto)
IF(LIBCRYPTO_FOUND)
INCLUDE_DIRECTORIES(${LIBCRYPTO_INCLUDE_DIRS})
LINK_DIRECTORIES(${LIBCRYPTO_LIB_DIRS})
ENDIF(LIBCRYPTO_FOUND)
I googled and found they always use system library first and can use find_package with NO_CMAKE_SYSTEM_PATH flag. But its not working and give me the following message. I don't know what its talking about..
Could not find a package configuration file provided by "libcrypto" with
any of the following names:
libcryptoConfig.cmake
libcrypto-config.cmake
Add the installation prefix of "libcrypto" to CMAKE_PREFIX_PATH or set
"libcrypto_DIR" to a directory containing one of the above files. If
"libcrypto" provides a separate development package or SDK, be sure it has
been installed.
My question is how to properly link a library to the path I assigned to and works like original piece of code?
I have compiled Lua 5.3 as a 32 bit c++ DLL and exe. The DLL contains all the lua code except for lua.cpp and luac.cpp. The exe compiles lua.cpp and uses the DLL to run the lua interpreter. This works fine when running on its own from the command line. I wish to be able to run from the IDE using this DLL and exe.
If I replace /ZeroBraneStudio/bin/lua53.dll and lua53.exe with my own versions, I can run scripts (clicking the two green arrows). However, debugging does not work, giving the following error:
The procedure entry point luaL_addlstring could not be located in the dynamic link library lua53.dll.
I can see that this is happening because the debugger is making use of luasocket. \ZeroBraneStudio\bin\clibs53\socket\core.dll is dependent on lua53.dll, and is expecting it to contain lua compiled as c.
So, what is the correct solution to this - is it to compile luasocket as c++ as well?
(And, if so, does anybody have instructions/guidance for doing so? I have been unable to find anything on this.)
Thanks.
I'm not sure how exactly the DLL was compiled, but the error message likely indicates that the luaL_addlstring and other functions are not exported by it. If the symbols are exported correctly, you should be able to load luasocket and get the debugging working. See this thread for the related discussion.
Also, you don't need to replace lua53 library and executable, as you can configure the IDE to use your own copy of it using path.lua53 configuration setting as described in the documentation.
Okay, I was able to get it working. The solution was to compile luasocket as c++. I won't give full instructions on how to do this here, but some points to hopefully help anybody else with the same issue:
Got luasocket from here: https://github.com/diegonehab/luasocket
Renamed all *.c files to *.cpp
Renamed Lua52.props to Lua.props (I am using lua 5.3 but seems like it is compatible?)
Placed lua headers and lib in appropriate folders
Opened solution in Visual Studio 2012
Fixed up minor issues with project files, like the renaming of the files.
Added 'extern "C"' to declaration of luaopen_socket_core and luaopen_mime_core functions (necessary for lua to be able to load libraries).
Built solution
Copied new dlls into clibs53/socket and clibs53/mime folders.
I used Dependency Walker to help with this. If anybody wants further details in the future please leave a comment.
So I have been trying to build libarchive for a couple of days now, following this guide and many other threads: https://github.com/libarchive/libarchive/wiki/BuildInstructions
I want a static library with LZMA, zlib and bzip2 support. I got static versions of these too (lib's)
I just cant get it to work properly. Ive used CMAKE to generate the make files for VS2010 and NMAKE. With both of these options the thing compiles just fine, but when i try to use the archive_static.lib generated, in my project I get plenty of unresolved externals. Compiling the .dll version of the library works without unresolved externals, but then it starts asking for zlib.dll, bzip2.dll etc, which i dont have and dont want to use.
I think i need to set some flags with cmake, but im not sure how to do that.
Any help is greatly appreciated.

I can't be sure if that's what happening here, but please bear in mind, that when linking binaries into a static library, its external dependencies do not necessarily get embedded into it, that means you might need to provide thet static libraries on which your program indirectly depends through libarchive, namely LZMA, zlib and bzip2 in your case, explicitly.
Furthermore there's some confusion on windows when it comes to linking static vs dynamic, for in both cases you provide a .lib file, so it is very easy to mix things up and provide the dynamicaly linked .lib, instead of the static version. If you do that, the linker may refuse to link your program (that notably happens with boost), or may link just fine and then, at the time of execution, the OS will require the respective .dll's.
I've now been trying to get MinGW-w64 to work on my system for several days, mainly because it has a more recent GCC version, but I either set things up wrong or there's some strange problem with MinGW-w64 itself.
I've now downloaded i686-w64-mingw32-gcc-4.7.2-release-win32_rubenvb, unpacked it to C:/Dev/mingw-ruben and added the path C:/Dev/mingw-ruben/bin to the $PATH environment variable.
What I'm trying to build is SFML 2 which comes with a CMake file. Running CMake will work just fine, the compiler gets recognized and passes all test. CMake also finds the ar.exe in the C:/Dev/mingw-ruben/binfolder. After generating the MinGW Makefile I switch to the windows command line and run mingw32-make install.
There's where the problem happens, I get the error:
mingw-ruben\bin\ar.exe: mingw-ruben/lib/libopengl32.a: No such file or directory
Or for the network library
mingw-ruben\bin\ar.exe: mingw-ruben/lib/libws2_32.a: No such file or directory
The error seems quite obvious and on check there really is no libopengl32.a or libws2_32.a in mingw-ruben/lib/, but the files is actually located in C:/Dev/mingw-ruben/i686-w64-mingw32/lib.
Now How can I tell ar/make/cmake to not only search in the mingw-ruben/lib directory but also in the mingw-ruben/i686-w64-mingw32/lib?
Would it be a good idea to copy all the content from the i686-w64-mingw32 subfolder to the mingw-ruben root folder?
As a side note: I can call mingw32-make install again and the procedure will continue but up on trying to link my application against SFML, I run into many unresolved symbol errors for the glXYZ functions from within SFML.
Further information: I'm on Windows 8 x64, but I think that doesn't really matter and yes I've tried MSYS but it doesn't resolve any of my issues.
Am I doing something wrong? Do I have to configure things specially?
January 2015 Edit
Now that SFML 2.2 has been released, this is no longer an issue and you have to link SFML's dependencies yourself when linking static.
January 2014 Edit
As of commit 165f2b1888 and f784fe4c07, which is included in the stable version SFML 2.1, MinGW-w64 compilers are supported.
However while discussing further with different parties it came to light, that the sfml_static_add_libraries marco a rather ugly hack was. In short it unpacked the static dependencies and included their obj files into the SFML library itself. This was most noticeable an issue, when trying to use your own version of GLEW, which failed since SFML was using its internal one already. The issue was brought to the forum and was pushed around for quite a bit, until Laurent finally gave in and went with the proper way of linking dependencies, which means you have to link them now on your own.
As of commit dbf01a775b, which is not included in the stable version of SFML 2.1, one has to link the SFML dependencies in the finally application, when linking statically against SFML.
Original
After some chat on the IRC we've figured it out.
It has nothing to do with MinGW but it's all SFML's fault. To reduce the dependencies list for SFML while linking statically the developer decided to manually extract the symbols from each library (opengl32, ws2_32, ...) which obviously isn't how one does things and violates some ODR rules. The actual error then occurs because the developer assumed that the library will be in the folder mingw/libbut with MinGW w64 it's located in a seperate directory mingw/version/lib and so ar.exe didn't find the library.
Solution
Removing the call to the sfml_static_add_libraries macro and then recompile. Afterwards you'll have to link all the dependencies for static linkages, like it should be.
I think it may be well a problem of the gcc distribution you downloaded.
A bit of light into the problem gives ruben's question here:
https://unix.stackexchange.com/questions/45277/executing-binary-file-file-not-found
that seems to me related to that (although it is about linux and not win)
I was having a similar problem (the name of the missing file was different) few months ago with gcc 4.7.0 linux->win crosscompiler. So until now I lived with the standard ubuntu mingw-w64 package and only yesterday I gave another try to i686-w64-mingw32-gcc-4.7.2-release-linux64_rubenvb.tar.xz and it works without issues in otherwise same environment where the previous version was failing with "..ar.exe: ... no such file". Sometimes I develop also in windows, then I use http://www.mingw.org/ that was for me much easier to setup in Win. It supports only 32bit target but for my project it is sufficient.
