build error from source

Hi,
I'm a engineer and I'm trying to use MuJoCo for simulation.
I'm looking for some help with build.
my environment:
ubuntu22.04,
gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
g++ (Ubuntu 7.5.0-6ubuntu2) 7.5.0
clang version 10.0.0-4ubuntu1
cmake version 3.22.1
I made some changes to the source code because the [-Werror=unused-variable] error, which is showed in the first picture. And then I encountered the following issue(s).
[ 0%] Built target lodepng
[ 1%] Built target ccd
[ 6%] Built target qhullstatic_r
[ 7%] Built target tinyxml2
[ 7%] Built target tinyobjloader
[ 9%] Linking CXX shared library lib/libmujoco.so
lto1: internal compiler error: compressed stream: data error
unrecognized DWARF version in .debug_info at 6
Please submit a full bug report,
with preprocessed source if appropriate.
See file:///usr/share/doc/gcc-7/README.Bugs for instructions.
lto-wrapper: fatal error: /usr/bin/c++ returned 1 exit status
compilation terminated.
/usr/bin/ld.gold: fatal error: lto-wrapper failed
collect2: error: ld returned 1 exit status
gmake[2]: *** [CMakeFiles/mujoco.dir/build.make:1095: lib/libmujoco.so.3.2.2] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:1605: CMakeFiles/mujoco.dir/all] Error 2
gmake: *** [Makefile:146: all] Error 2
So I want to know is there anything wrong with my environment? What I should do to solve this error?
Maybe there's something wrong with the picture, but the changes are just adding lines like 'static_cast(name); // Silence -Wunused-variable.' Nothing else has been modified.
Did you try deleting this line?
I found that all the errors disappeared after I upgraded g++ from 7.5.0 to 11， even after I deleted “-Wunused” in
mujoco/cmake/MujocoOptions.cmake
