MSYS2/Mingw-w64: --no-cmake-config causes fiber and stacktrace to be ignored by the build system, no reason shown

[oscarfv]

With 1.78 the same build process that previously worked correctly now doesn't build boost_fiber nor boost_stacktrace. The build does not fail, they are simply ignored.

We are using gcc 11.2.

This are the arguments passed to b2 (this sample only builds boost_fiber):

address-model=64 \
    --with-fiber \
    link=shared,static \
    pch=off \
    runtime-link=shared \
    threading=multi \
    threadapi=win32 \
    toolset=gcc \
    variant=release \
    python=${_pyver} \
    --debug-configuration \
    --prefix=${pkgdir}${MINGW_PREFIX} \
    --layout=tagged \
    --no-cmake-config \
    -sHAVE_ICU=1 \
    -sICU_LINK=\"-L${MINGW_PREFIX}/lib -licuuc -licuin -licudt\" \
    -sICU_PATH=${MINGW_PREFIX} \
    -sICU_ICUUC_NAME=icuuc \
    -sICU_ICUDT_NAME=icudt \
    -sICU_ICUIN_NAME=icuin \
    -sICONV_PATH=${MINGW_PREFIX} \
    -sICONV_LINK=\"-L${MINGW_PREFIX}/lib -liconv\" \
    -sNO_BZIP2 \
    -sBZIP2_BINARY=bz2 \
    -sBZIP2_INCLUDE=${MINGW_PREFIX}/include \
    -sBZIP2_LIBPATH=${MINGW_PREFIX}/lib \
    -sNO_ZLIB \
    -sZLIB_BINARY=z \
    -sZLIB_INCLUDE=${MINGW_PREFIX}/include \
    -sZLIB_LIBPATH=${MINGW_PREFIX}/lib \
    -d2 \
    -q

And this is the build output. As you can see, b2 reports that the build is complete, but boost_fiber was not built:

The Boost C++ Libraries were successfully built!

The following directory should be added to compiler include paths:

    D:\dev\other\MINGW-packages\mingw-w64-boost\src\build-x86_64-w64-mingw32

The following directory should be added to linker library paths:

It turns out that removing --no-cmake-config from the command line fixes the build.

[oscarfv]

Removing --no-cmake-config does not totally resolve the problem: for fiber and stacktrace the libraries are built, but not copied to /stage. Tested with:

b2 address-model=64 link=shared,static pch=off runtime-link=shared threading=multi threadapi=win32 toolset=gcc variant=release --layout=tagged -d2 stage

They are not installed either after b2 ... install.
