How to fix it ?

[gitdou8679]

Hello, I have the same problem with rhel 9.1.
Tried with osrm-backend with master branch and tag v5.27.1 ; and also v5.26.0, but different problems

My process : I had to install a lot of packages (If I compare to the Wiki for Centos 8.x (tbb-devel boost-devel expat-devel bzip2-devel lua-devel lua-devel doxygen))

git clone https://github.com/Project-OSRM/osrm-backend.git
cd osrm-backend
mkdir build
cd build
cmake3 .. -DENABLE_MASON=ON -DCMAKE_CXX_COMPILER=/opt/rh/gcc-toolset-12/root/usr/bin/g++
make

# Same with the snipe404 commands :
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .

Edit 03/04/2023 :
To have something working :
I had to pass to RHEL 8 and with a backend on 5.26.0 (2.27.x is not compatible)

Dirty hack: define LUA_COMPAT_5_2 to 1 in /usr/include/luaconf-x86_64.h (it is empty by default).
