Build error on Arch Linux GCC14

[ProgrammerIn-wonderland]

Hello, I am trying to build this project on arch linux, I have the dependencies installed and the build setup succeeds with the commandline meson setup build -Dsdl=true -Dvgpu=true however the build command fails as follows

alice@Felix ~/git-applications/mvisor/mvisor$ meson compile -C build

same error on GCC-11 with setup command CC=gcc-11 CXX=g++-11 meson setup build -Dsdl=true -Dvgpu=true

[78]

Try to use scl enable gcc-toolset-11 or the following commands to setup compiler.

export PATH=/usr/local/gcc-11.4.1/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/gcc-11.4.1/lib64:$LD_LIBRARY_PATH

It seems the error was occurred in verify.h.
You can also try to replace the macro empty to ignore the assertion line.

#define _GL_VERIFY_TYPE(R, DIAGNOSTIC) { }

[78]

If you're not using virtio-vgpu, which emulates an OpenGL-compatible GPU within the guest operating system, you should remove the flag -Dvgpu=true.

[ProgrammerIn-wonderland]

I get the same error without vgpu and setup command
meson setup build -Dsdl=true
I managed to circumvent the error by unincluding verify.h and commenting out all SPICE_VERIFY

EDIT: this makes it build however runtime gives me an assertion error

this patch seems to work for archlinux, it just removes all usage of verify.h

[78]

This header file verify.h comes from the Spice Common project. I'm uncertain about the implications of commenting out these asserts, but they can be replaced with MV_ASSERT, which would require including "logger.h". If an assert fails, it demands special attention.

[youfun]

it seem the same error in void linux when bulid.

 meson setup build -Dsdl=true
Directory already configured.

Just run your build command (e.g. ninja) and Meson will regenerate as necessary.
Run "meson setup --reconfigure to force Meson to regenerate.

If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.

It seems you have configured virtio-vgpu before.
Remove the build directory and run meson setup build -Dsdl=true again.
