Jim Wilson <wilson at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |wilson at gcc dot gnu.org --- Comment #9 from Jim Wilson <wilson at gcc dot gnu.org> --- Building and using glibc is complicated. It is best to refer to a FAQ if you haven't done this before. You can find some info on the glibc wiki about this here: https://sourceware.org/glibc/wiki/Testing/Builds You probably want item 5. It is a little simpler if you build a gcc that is set up to use your glibc build, which requires building a complete toolchain from scratch. If you want to learn how to do this, it is best to look at someone else's scripts showing how to do it. Every linux distro has scripts for this. I like to use crosstools-ng. You can find some info on how to build a toolchain here: https://crosstool-ng.github.io/docs/toolchain-construction/ and look at the scripts if you want the details of how this works.
