Re: issue with creating toolchain with lfs versions

Seems to have figured out one issue partially using a separate script as recommended than the build system and thought of sharing this.

I was using x86_64-pc-linux-gnu where it is failing at below error but the error is gone if using x86_64-lfs-linux-gnu. Change is from pc to lfs.

This was the error in gcc-pass-1
> configure:2634: error: in `/tmp/work_debian12/0000_toolchain/src/gcc-pass-1/
> build/intl':
> configure:2636: error: C compiler cannot create executables


Thanks

Apologize for top posting. Saw the email address was missing and added it.

My challenge is I had to use crux's pkgutils's pkgmk as the build system and unfortunately cannot go out of it.

Will try to rerun the scenario and check.

Thanks

First, stop top posting.  On mailing lists we post of the bottom to maintain context.
We also trim off non relevant portions of prior posts.

For your problem.  LFS-12.0 should be OK to act as a host system.

I think you should stop trying to use a package manager.  Just start over and build
by hand watching each command to see that it works properly.

1. Start at Section 2.5 Creating a File System on the Partition.
2. Use LFS-14.4 stable.
3. Carefully copy each command and paste it into the terminal where you have placed
    the sources, but see Section iii. General Compilation Instructions.
    Read the 2nd Important note (twice).  Make sure you understand it.
4. Copy each command from the html version of the book and paste it to the
    location of the expansion of the current package tarball. Check that it
    is doing the right thing.

If you find a problem report it.  Also add the output of "free -h' and
'lscpu | head -n 18'
