linux to freebsd cross compiler
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:

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?
Re: linux to freebsd cross compiler
Code:
#include <sys/_types.h>
The problem is here. The compiler cannot find the file sys/_types.h. This is either because the compiler cannot find the directory sys within the defined include paths or within the sys directory the file _types.h does not exist.
Does the file _types.h exist on the system somewhere and if it does has the required include directories been specified properly?

Yes, I know, and I found _types.h in /usr/include/freebsd/sys.
Now?

Change the #include so it finds the path or set up the includes path to include this path.

Obviously this is not a good way because I'm building a program like gcc for another target.
However I found the solution and so, also, my error: 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! :D
