Unsolved How to tell MOC to exclude gcc related includes to avoid problem like:Parse error at "std"?
-
Hello,below moc statement: :
/usr/lib/qt5/bin/moc -DJSON_DIAGNOSTICS=0 -DJSON_USE_IMPLICIT_CONVERSIONS=1 "-DvtkRenderingCore_AUTOINIT_INCLUDE=\"/home/alex/workspace/MTESS/build/CMakeFiles/vtkModuleAutoInit_be7301261a49b13d6a9b1d9e110eacd8.h\"" -I/home/alex/workspace/MTESS/src -I/home/alex/workspace/MTESS/vendor/ProjectStructure -I/home/alex/workspace/MTESS/vendor/imgui -I/home/alex/workspace/MTESS/vendor/imgui/imgui -I/usr/include/x86_64-linux-gnu/qt5 -I/usr/local/qwt-6.2.0/include -I/usr/local/include/opencascade -I/lib -I/usr/local/include -I/usr/include/c++/11 -I/usr/include/x86_64-linux-gnu/c++/11 -I/usr/include/c++/11/backward -I/usr/lib/llvm-14/lib/clang/14.0.0/include -I/usr/include/x86_64-linux-gnu -I/usr/include --include /home/alex/workspace/MTESS/build/MTESS_autogen/moc_predefs.h --output-dep-file -o /home/alex/workspace/MTESS/build/MTESS_autogen/MLM4FWGUYC/moc_NearFieldProcessUtil.cpp /home/alex/workspace/MTESS/src/Layers/ViewLayer/Process/NearFieldProcessUtil.h
will give error :
usr/include/c++/11/bits/fs_fwd.:39: Parse error at "std"
If removing:
-I/usr/local/include -I/usr/include/c++/11 -I/usr/include/x86_64-linux-gnu/c++/11 -I/usr/include/c++/11/backward
from above statement,then run:
/usr/lib/qt5/bin/moc -DJSON_DIAGNOSTICS=0 -DJSON_USE_IMPLICIT_CONVERSIONS=1 "-DvtkRenderingCore_AUTOINIT_INCLUDE=\"/home/alex/workspace/MTESS/build/CMakeFiles/vtkModuleAutoInit_be7301261a49b13d6a9b1d9e110eacd8.h\"" -I/home/alex/workspace/MTESS/src -I/home/alex/workspace/MTESS/vendor/ProjectStructure -I/home/alex/workspace/MTESS/vendor/imgui -I/home/alex/workspace/MTESS/vendor/imgui/imgui -I/usr/include/x86_64-linux-gnu/qt5 -I/usr/local/qwt-6.2.0/include -I/usr/local/include/opencascade -I/lib -I/usr/lib/llvm-14/lib/clang/14.0.0/include -I/usr/include/x86_64-linux-gnu -I/usr/include --include /home/alex/workspace/MTESS/build/MTESS_autogen/moc_predefs.h --output-dep-file -o /home/alex/workspace/MTESS/build/MTESS_autogen/MLM4FWGUYC/moc_NearFieldProcessUtil.cpp /home/alex/workspace/MTESS/src/Layers/ViewLayer/Process/NearFieldProcessUtil.h
The expected file:
moc_NearFieldProcessUtil.cpp
got generated successfully,so my question is :
When using CMake to compile QT app in linux,How to tell MOC to exclude gcc related includes?
-
From the very end of the Command-Line Options section:
You can explicitly tell the moc not to parse parts of a header file. moc defines the preprocessor symbol Q_MOC_RUN. Any code surrounded by
#ifndef Q_MOC_RUN ... #endif
is skipped by the moc.

@jeremy_k Thanks,I want to exclude all gcc headers which is not created by myself,but comes from GCC.
