Wouldn't it be better to make wine an optional dependency? A lot of packages using this wrapper at build time but don't require wine.

Oh I didn't know strip could remove the debug symbols, I always thought it was for removing useless ones. I will double check if it produces the same executable once stripped, thanks.

I think xantares' explanation makes sense: "-g -O2" makes great sense actually: when you're debugging you want your code to behave like the the release code in order to better reproduce bugs. Debug symbols are actually removed by the strip commands ... .

Can you also remove the -g flag from the CFLAGS in the CMake script? I wonder why is it enabled globally as it's only relevant in Debug builds. Thanks.

markand: I noticed the same problem with some of my own projects (qtutilities) and wasn't able to fix it yet. The problem occurred with a mingw-w64-gcc update, but actually it is CMake which messes the include paths. It is still unclear to me why this happens but I'll try your fix. If it works, I would also vote for including it here.

After some investigation and tests with ngladitz from the #cmake channel, I figured out how to fix. We need to set CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES to make it work. Would you mind adding this to the x86_64-w64-mingw32-cmake (and same for 32 bits) -DCMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES:PATH=${mingw_prefix}/include \ -DCMAKE_C_IMPLICIT_INCLUDE_DIRECTORIES:PATH=${mingw_prefix}/include \

I don't know if it's a CMake problem, but once I try to build a program that links to mingw-w64-openssl library, the include headers are broken. This is a test project: cmake_minimum_required(VERSION 3.5) project(test) set(CMAKE_CXX_STANDARD 14) set(CMAKE_CXX_STANDARD_REQUIRED On) find_package(OpenSSL REQUIRED) add_executable(main main.cpp) target_link_libraries(main OpenSSL::SSL OpenSSL::Crypto) Compiling like this: x86_64-w64-mingw32-cmake . make Ends with that error: In file included from /tmp/test/main.cpp:1:0: /usr/x86_64-w64-mingw32/include/c++/6.1.1/cstdlib:75:25: fatal error: stdlib.h: No such file or directory #include_next <stdlib.h> However, removing the last target_link_libraries builds successfully. The includes specified by cmake are defined as: -isystem /usr/x86_64-w64-mingw32/include I could not find anything in the FindOpenSSL.cmake that use this directory. EDIT: after some investigation, it seems that any libraries linked to the project break it. I can reproduce the same problem with FindPNG package and mingw-w64-libpng.

You can override the -02 flag by appending -O0, ie "-O2 -O0" are valid CFLAGS, the last (-O0) value overrides the level 2 optimization O2.

Martchus commented on 2016-07-13 19:59 (UTC)

Of course I know that debug symbols are stripped anyways. I was just wondering about the combination with -O2 but your explanation makes sense. I just mentioned -g because I've read the previous discussion. Actually I want to get rid of -O2 as a workaround for the mentioned issue (see my first comment). Hence overwriting (and not just appending) would still be useful for me. Maybe there are other use cases, too. If you like, you can try to reproduce the issue (should only take 1 minute).

xantares commented on 2016-07-13 19:40 (UTC)

"-g -O2" makes great sense actually: when you're debugging you want your code to behave like the the release code in order to better reproduce bugs. Debug symbols are actually removed by the strip commands so if you wanted to override flags just to disable -g it's useless. xan.
