Description

This is a follow up from #10761

If cmake fails to parse the gcc output of implicit include dirs, it will add the system paths via -isystem, which is not supported by GCC and will result in something like:

C:/msys64/mingw64/include/c++/11.2.0/cstdlib:75:15: fatal error: stdlib.h: No such file or directory
   75 | #include_next <stdlib.h>
      |               ^~~~~~~~~~

I've noted the packages for which this happened in CI recently:

  • mingw-w64-qt6-3d
  • mingw-w64-qt6-webview
  • mingw-w64-aws-crt-cpp
  • qt-creator
  • qt6-webchanne
  • qt6-webchannel
  • openshadinglanguage
  • mingw-w64-kitemmodels-qt5
  • mingw-w64-protobuf
  • mingw-w64-cppcheck

so in all cases cmake+ninja.

I've had a similar issue happen due to a ninja issue, see #12262.
There you could see in "CMakeOutout.log" you should find a warn: unable to parse implicit include dirs!

My guess is that cmake calls gcc via ninja, and stderr/stdout gets re-ordered sometimes.

Verification

Windows Version

MINGW64_NT-10.0-22621

MINGW environments affected

  • MINGW64
  • MINGW32
  • UCRT64
  • CLANG64
  • CLANG32
  • CLANGARM64

Expected behavior

It builds

Actual behavior

It fails, sometimes

Repro steps

unclear

Are you willing to submit a PR?

That might be related to msys2/MSYS2-packages#3259
Maybe, those additional include paths are messing with the order of isystem paths?

It affects only UCRT64, so I don't think It's related.

If someone knows a way to reproduce this locally (even if only in some cases), please let us know. I've only seen it in CI up until now.

I have reproduced this issue once but forgot which package. The issue disappears after deleting pkg and src directories. I ran ninja multiple times before deleting the build directory and it fails with same compiler error.

It would be helpful if you can provide what steps one should follow after catching this issue. For example, what files should be examined, what clues should be searched for ...

All I know is what I wrote in the original post above.

If my guess above is correct then adding message(STATUS ${CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES}) to the cmake file should show it as empty, and you have to debug back from there and figure out why it's empty.

I think experience this if I add target_link_libraries(waui-demo PRIVATE SDL2::SDL2-static) to my CMakeLists.txt.

Without:

g++ -DSDL_MAIN_HANDLED -I/mingw64/include -I/mingw64/include/SDL2 -O3 -std=gnu++17 -MD -MT CMakeFiles/waui-demo.dir/src/main.cpp.obj -MF CMakeFiles/waui-demo.dir/src/main.cpp.obj.d -o CMakeFiles/waui-demo.dir/src/main.cpp.obj -c /c/users/wareya/dev/waui/src/main.cpp

(compiles but fails to link)

With:

g++ -DSDL_MAIN_HANDLED -isystem /mingw64/include -isystem /mingw64/include/SDL2 -O3 -std=gnu++17 -MD -MT CMakeFiles/waui-demo.dir/src/main.cpp.obj -MF CMakeFiles/waui-demo.dir/src/main.cpp.obj.d -o CMakeFiles/waui-demo.dir/src/main.cpp.obj -c /c/users/wareya/dev/waui/src/main.cpp

add_executable(waui-demo src/main.cpp)
target_link_libraries(waui-demo PRIVATE SDL2::SDL2-static)
add_definitions(-DSDL_MAIN_HANDLED)

I need to set set(CMAKE_CXX_COMPILER g++) explicitly because otherwise (at least on my system?) it tries to use gcc instead of g++ and fails to link the C++ standard library. Might be connected?

-- Check for working CXX compiler: /mingw64/bin/CC.exe - skipped

EDIT: I'm using MINGW64, not UCRT64.

It looks like you are using a cygwin cmake with a mingw toolchain. try pacman -S mingw-w64-x86_64-cmake

The issue is similar in that cmake fails to parse the implicit system include dirs from the compiler, and continues with a broken setup instead of erroring out. Though the cause is different in your case.

I mentioned on 2024-01-25 in chat that I haven't seen this issue in CI for a while, and indeed it hasn't happened since as far as I'm aware of.

So maybe something fixed it (in cmake, ninja, ucrt, ?) or it's still broken but we no longer hit it somehow.

Let's close this.

If this still happens for someone please let us know!

There's something dubious in CmakeConfigureLog.yaml; the first line seems corrupt:

-pipe seems to cause GNU AS to produce garbage text (not necessarily error messages) which can interleave with GCC output. If it happens to jam #include "..." search starts here: of GCC output, then CMake fails to parse default include directories, and adds -isystem C:/MSYS64/ucrt64/include which will cause errors later.

Without -pipe it does not interleave.

However there shouldn't be any messages from GNU AS. It can happen if CMake attempts to compile something into a non-existent directory which fails; but is it expected?

There is no -no-pipe to turn off that option so I have removed it from '/etc/makepkg_mingw.conf', and the error seems gone now.
