Linux From Scratch problem - final gcc build

aidan_walsh

Hey guys,

I'm going a Linux From Scratch project in my spare time at home and really enjoying it. However, I am after getting stuck on the final gcc compile (latest stable v6.5, Ch 6.15). It configures and builds as far as libgcc correctly, but starts failing with the following error at this point:

Checking multilib configuration for libgcc...

I've gone through the mailing lists, documentation and Google and can't find anything helpful for this phase of the build. I know it can be a common problem for ncurses if the compiler isn't installed correctly, but it seems to be finding the correct versions of gcc and g++.

I am also attaching the config.log file, but I can't see what might be causing problems in it.

Thanks.

Had been rebuilding with new build directories, but never thought to trash the source and try again. Now seems to be working correctly, but I'll await the test suite results before I cry victory

Good to hear. Was going to try LFS out myself, but I am working
on a pretty secret project right now:D More to come...

It boots!

I messed up the network interface script, so I will need to look at that before I can get her online, but it boots!
