Re: [Mingw-w64-public] MinGW-w64 + MSYS: g++ can't include files with unix style prefix?
08 авг. 2014 г., в 20:06, Richard Shaw hobbes1...@gmail.com написал(а): Ok, a bit of an update... I got MSYS2 installed and after I figured out pacman I got mingw-w64 installed. It is nice having it integrated instead of two separate installations. Also, most of my dependencies were available so I didn't have to build as much. One notable exception is sox. Just for the heck of it I did the sox build with ninja which was interesting. Worked fine. Now I'm trying to build the final project and I'm guessing this is a cmake bug: cd /C/Tools/Projects/freedv/src /C/msys32/mingw32/bin/g++.exe -DHAVE_CONFIG_H -DSVN_REVISION=\1786M\ -DWXUSINGDLL -D_FILE_OFFSET_BITS=64 -D_NO_AUTOTOOLS_ -D__WXMSW__ -Wall -mthreads;-fpermissive -g -I/C/Tools/Projects/freedv -I/C/msys32/mingw32/include -I/C/msys32/usr/local/include -isystem /mingw32/lib/wx/include/msw-unicode-3.0 -isystem /mingw32/include/wx-3.0 -I/C/msys32/usr/local/include/codec2 -I/C/Tools/Projects/svn/freetel/fdmdv2/src-o CMakeFiles/freedv.dir/dlg_about.cpp.obj -c /C/Tools/Projects/svn/freetel/fdmdv2/src/dlg_about.cpp g++.exe: fatal error: no input files compilation terminated. There is a ; working it's way in between the -mthreads and -fpermissive option and I don't know where it's coming from. This is with the MSYS makefiles. I tried Ninja but for some reason cmake fails to find wxWidgets which is odd, I would think that would be independent of the generator used. This is known issue. Think this is cmake error parsing flags from wxwidgets config file. Don’t have time yet to fix it. Regards, Alexey. Thanks, Richard -- Want fast and easy access to all the code in your enterprise?

[Mingw-w64-public] MinGW-w64 + MSYS: g++ can't include files with unix style prefix?
I'm working on documenting how to build a project natively in windows, which first means figuring out the quirks myself and I ran into an issue with g++ not being able to find headers with unix style paths /usr/local/include. My environment: Windows 7 32bit mingw-w64 from win-builds.org MSYS from the MinGW-w64 sourceforge page The project requires wxWidgets which I have building and installing fine with no tweaks. In order to determine C/CXX flags, linker requirements, etc, wxWigets provides a script wx-config that provides them. My project is cmake based (if it matters) and I'm using the built-in FindWxWidgets/UseWxWidgets modules for library and inclide directory detection (which uses wx-config on *nix systems). The problem occurs when I try to build my project: cd /C/Tools/Projects/freedv/src /C/Tools/msys/opt/windows_32/bin/g++.exe -D HAVE_CONFIG_H -DSVN_REVISION=\1786M\ -D_FILE_OFFSET_BITS=64 -D_NO_AUTOTOOLS_ - D__WXMSW__ -Wall -mthreads -g @CMakeFiles/freedv.dir/includes_CXX.rsp -o CMake Files/freedv.dir/dlg_about.cpp.obj -c /C/Tools/Projects/svn/freetel/fdmdv2/src/d lg_about.cpp c:/Tools/Projects/svn/freetel/fdmdv2/src/dlg_about.cpp:21:22: fatal error: wx/ff ile.h: No such file or directory #include wx/ffile.h ^ compilation terminated.

Isn't the whole point of msys is so that you can use unix style paths? The compiler does not depend on MSYS, which acts as a POSIX compatibility layer. MinGW(-w64) compiler, linker, etc don't know about those fictional paths that MSYS creates. The point of MSYS is to provide an environment for running sotfware that hasn't been ported to Windows and requires a POSIX environment, such as configure scripts. -- Infragistics Professional Build stunning WinForms apps today!

Am I missing something obvious here? Isn't the whole point of msys is so that you can use unix style paths? Yes, you are missing something here, whether it's obvious or not depends on how long you've spent working with MSYS* and MinGW-w64. MSYS will convert paths when it gets a chance to and thinks it should, for example when calling a native Windows program like GCC. At that time it will look through the command line and environment variables with knowledge of the mount points and convert things that appear to be path-y. However, you're using CMake here and it's emitted MSYS paths into @response files (the .rsp files) and then native GCC has been told to process those files, so MSYS doesn't get another chance to transform them. Emitting stuff to a file isn't a good place to transform paths because it's not known what tool will process those files and it'd be horribly slow and break in a million different ways if transformations were applied to all file IO. My recommendation is to dump MSYS and use MSYS2 as it's way better (if you do that you can use a huge amount of prebuilt libraries) but otherwise figure out how to stop whatever version of CMake you are using from using response files.
