linux to freebsd cross compiler

NickF_93 · 03-13-2015, 09:48 PM

I was trying to compile a gcc cross compiler for linux x86_64 (build and host) to freebsd x86_64.
I tried to follow this http://marcelog.github.io/articles/articles.html and then some other guides around the web, but I continue to get this:

Code:

...

this is the lasts logs of make process of gcc-4.9.2 sources with TARGET=x86_64-freebsd10.1

what I'm doing wrong? Any ideas?

Solved.

I didn't set up properly sysroot.

I had to dowload (or take it from a build and working system) the target system on my machine and then I was able to set --with-sysroot in configuration process of binutils and gcc sources, and then run

$ make
and
# make install

And finally I got my toolchain!
