@kiufta are you sure it is inside sol2? I see only warnings from there and no error message.

[lliehu]

Today I tried to build git master under latest Arch Linux and got the same build failure.

The build only failed when I set CMAKE_BUILD_TYPE=Release according to instructions at https://github.com/Project-OSRM/osrm-backend/wiki/Building-OSRM. It looks like this build type causes compiler warnings to be treated as errors and this is why the warnings mentioned above caused the build to fail. At first I tried to build git master without setting CMAKE_BUILD_TYPE and that succeeded.

Used compiler version: gcc (GCC) 12.2.1 20230201

Received console output:

[nik498]

I had the error even when I didn't specify CMAKE_BUILD_TYPE=Release. I tried compiling with gcc 12.2 on Ubuntu 22.04 and 22.10, it finally worked when I downgraded to gcc 11.3.

[tillschaefer]

Can reproduce on Debian Bookworm.

The build only failed when I set CMAKE_BUILD_TYPE=Release according to instructions at https://github.com/Project-OSRM/osrm-backend/wiki/Building-OSRM. It looks like this build type causes compiler warnings to be treated as errors and this is why the warnings mentioned above caused the build to fail. At first I tried to build git master without setting

I do not think this is the case. Using build type Debug does not even produce the warning. Maybe its an issue with compiler optimization itself.

[lliehu]

I do not think this is the case. Using build type Debug does not even produce the warning. Maybe its an issue with compiler optimization itself.

Good point. Didn't think to check that. Now was able to make the warning go away just by switching optimization level from Release default -O3 to -Og.

[SiarheiFedartsou]

On CI we just turn this warning off for gcc 12 https://github.com/Project-OSRM/osrm-backend/blob/0ca913132acea46e0c56e4665af50d68f53eec68/.github/workflows/osrm-backend.yml#L224

fyi

• the -Wuninitialized errors should be gone with boost >= 1.80, see https://github.com/boostorg/function/commit/5b4e2797a28f9477d2df5fa915409dac73ff00c6
• the -Werror=array-bounds of sol2-3.3.0 can be fixed by lowering the optimization level to -O2

[RhinoDevel]

In case you are not a cmake user and just want to compile in release mode (like me)

cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-Wno-array-bounds -Wno-uninitialized"

will do the trick (tested with Debian 12.1 and OSRM release 5.27.1).

In reference to Building OSRM.
