I am looking to make use of gcc 8/9 on CentOS 7, which is currently with gcc 4.8.5. How do I go about doing this? SCL repository provides the same as part of devtoolset8, but devtoolset8 libstdc++-devel i686 package is missing, without which I can not build 32 bit applications.
Are there any repository sources from where I can get this? Otherwise, I am open to building the packages from sources. Please let me know how can one go about this.
Any suggestions and pointers appreciated.
