How to build smokegen on Linux?

[hakonhagland]

I am on Ubuntu 21.10, clang version 13.0, Qt version 5.14.2. I tried this:

$ git clone git@github.com:commonqt/smokegen.git
$ cd smokegen
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/opt/qt/smokegen -DCMAKE_PREFIX_PATH=/opt/qt/qtbase/lib/cmake/Qt5 \
      -DQt5_DIR=/opt/qt/qtbase -DCMAKE_BUILD_TYPE=Release

Sorry it seems like it used gcc instead of clang, here is a new try (it still produces similar errors) with clang:

Similar problem here.

Yes problem seems to be with LLVM-13, it compiles with no error if change to version 11:

/bin/clang++-11 -DQT_CORE_LIB -DQT_NO_DEBUG -DQT_XML_LIB -D__GENERATOR_BUILDING \
     -Dsmokegen_EXPORTS -I/usr/lib/llvm-11/include \

     -fno-exceptions -fPIC -o CMakeFiles/smokegen.dir/astvisitor.cpp.o \

Recompiling with clang-11 and LLVM-11 now gives one error:

main.cpp:61:5: error: cannot use 'try' with exceptions disabled
