What were you trying to do that didn't work?

Try to compile manticore search with CLANG.

Please provide the package NVR for which bug is seen:

16.0.6-1.el9

How reproducible:

always

Steps to reproduce

1. podman run --rm -ti --entrypoint /bin/sh quay.io/centos/centos:stream9
2. in the container:

   export SEARCHD_REF=6.2.12 SEARCHD_REPO=https://github.com/manticoresoftware/manticoresearch.git CC=clang-16 CXX=clang++-16 BUILD_PATH=/tmp/manticore_uselessly_long_path_to_prevent_rpm_build_issues BUILD_FLAGS="-DUSE_SYSLOG=0 -DWITH_GALERA=0 -DWITH_RE2=0 -DWITH_STEMMER=0 -DWITH_ICU=1 -DWITH_SSL=1 -DWITH_ZLIB=1 -DWITH_ODBC=0 -DWITH_EXPAT=0 -DWITH_ICONV=1 -DWITH_POSTGRESQL=0 -DWITH_MYSQL=0 -DBUILD_TESTING=0"
   mkdir /tmp/manticore_uselessly_long_path_to_prevent_rpm_build_issues
   cd /tmp/manticore_uselessly_long_path_to_prevent_rpm_build_issues
   yum install -y --setopt=skip_missing_names_on_install=False,tsflags=nodocs llvm-toolset mysql cmake boost-devel openssl-devel zlib-devel bison flex systemd-units rpm-build git
   git clone --depth=1 --branch=$SEARCHD_REF $SEARCHD_REPO .
   sed -i -e 's/Boost_USE_STATIC_LIBS ON/Boost_USE_STATIC_LIBS OFF/' src/CMakeLists.txt
   mkdir build && cd build
   cmake $BUILD_FLAGS ..
   cmake --build . --target package --config RelWithDebInfo
   

Expected results

compilation to succeed

Actual results

CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:66 (message):
  The C compiler

    "/usr/bin/clang-16"

  is not able to compile a simple test program.

  It fails with the following output:

    Change Dir: /tmp/manticore_uselessly_long_path_to_prevent_rpm_build_issues/build/CMakeFiles/CMakeTmp

I believe this issue is same as the Fedora issue:
https://bugzilla.redhat.com/show_bug.cgi?id=2209635
https://gitlab.com/qemu-project/qemu/-/issues/1668

Because at one of the attempts I've got an error message that I'm not anymore sure how to reproduce

clang-16: error: unsupported option '--driver-mode=g++'; did you mean '--driver-mode=g++'?
