glibc Cross Compile Configure Error

I would like to cross compile glibc. But, I ‘m getting an error.

• glibc version is 2.24.
• I tried compiling host and target i686-elf.
• My $MACHTYPE environment label is x86_64-pc-linux-gnu.
• Target directory includes binutils-2.27 and gcc-6.2.0.

• My PATH environment is:

  /home/ercan/cross/tools/tools_binaries/i686/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Console output have been listing to below:

It is not configured and config.log that is in build-glibc which content has been listing below:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU C Library configure (see version.h), which was
generated by GNU Autoconf 2.69.  Invocation command line was

How I cross compile glibc for i686-elf? Thanks for replies.

Answer

You are trying to build glibc for a bare metal target. This won’t work as far as I know.
Use newlib if the target is in fact bare metal.

For linux targets, use --host=i686-pc-linux-gnu instead, and pass CC=i686-elf-gcc to configure if necessary.
