Trouble with cross compiler - "cannot compute suffix"

[mango]

I'm getting started with Bare Bones, and the as a first step am creating a cross compiler on Debian Wheezy. All the gcc related steps are working, but I'm having trouble building libgcc. When I run make all-target-libgcc, I get

Code: Select all

checking for suffix of object files... configure: error: in `/home/vagrant/src/build-gcc/i686-elf/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

The config.log file has:

Code: Select all

I tried adding the path to the libmpc, libgmp, and libmpfr to the ld path, but got the same result. I have multiple libmpc.so files in /usr/lib/i386-linux-gnu, not sure if that is an issue, as I both apt-getted those libraries and ran the gcc dependency download script. Anybody been here before?

This seems unusually odd. Can you please dump all your environmental variables using env (1) and provide a full log of everything you typed and all the output? I couldn't spot the issue from the above log. Does your compiler work?

The output for env is:

I have no idea what more to do. The binaries are all in the right place and seem to work, it's just libgcc that's failing. Since this is all on a vagrant debian box I'm considering wiping it and starting fresh.

Hi. When I asked for the commands and output above, I meant you must delete the build directory and start over. Paste all the terminal scrollback, including the commands you typed, in a single log.

Mind that the leading : in LD_LIBRARY_PATH means the current directory, it is a bad thing to do that.
