> I did install gcc 8 from devtoolset-8 (SCL repo). However I am unable to
compile 32-bit programs because devtoolset-8-libstdc++-devel.i686 package
is missing from CentOS SCL repository. This is mentioned here
<https://bugzilla.redhat.com/show_bug.cgi?id=1642077> as well.

g++ -m32 helloworld.cpp
skipping incompatible
when searching for -lstdc++_nonshared
/opt/rh/devtoolset-8/root/usr/libexec/gcc/x86_64-redhat-linux/8/ld: cannot
find -lstdc++_nonshared
collect2: error: ld returned 1 exit status

Are there any plans to add the missing i686 package? Otherwise, what other
options does one have to get to gcc 8/9?

Further, where can I find the srpm file for the devtoolset-8 packages. One
way would be to use the srpm to rebuild.
