cachelib fails to build about cachelib

[jaesoo-fb]

Hi @george-reilly-wdc,

To clarify, build-cachelib-centos-8-1.yml mentioned in #275 is not a repo. It is just a file in CacheLib repo which is basically a script to build CacheLib on docker container of Centos 8.1.

For the build issue, what is the version of the gcc? I think this might be the same known issue on older version of OS including Ubuntu 18; e.g., build.

Hopefully, this will be resolved by reinstalling/updating tool chain following build-cachelib-centos-8-1.yml?

Hi Jaesoo-fb,

[root@fb-yv3-s1-n3 ~]# gcc --version
gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4)

Hi @george-reilly-wdc

Are you still experiencing this issue? I had a chance to repro this and confirmed that the build works with gcc-11 at least. Something like below worked for me.

$ dnf install -y gcc-toolset-11-gcc gcc-toolset-11-gcc-c++
$ update-alternatives --install /usr/bin/gcc gcc /opt/rh/gcc-toolset-11/root/usr/bin/gcc 110 --slave /usr/bin/g++ g++ /opt/rh/gcc-toolset-11/root/usr/bin/g++ --slave /usr/bin/gcov gcov /opt/rh/gcc-toolset-11/root/usr/bin/gcov --slave /usr/bin/gcc-ar gcc-ar /opt/rh/gcc-toolset-11/root/usr/bin/gcc-ar --slave /usr/bin/gcc-ranlib gcc-ranlib /opt/rh/gcc-toolset-11/root/usr/bin/gcc-ranlib  --slave /usr/bin/cpp cpp /opt/rh/gcc-toolset-11/root/usr/bin/cpp

I think you might first need to uninstall gcc if you already installed.
