Hi
I've been trying to build a cross-compiler for sparc but havent got much
luck :(
I've configure GCC with:
../gcc-4.4.3/configure --target=sparc-edisoft-rtems --with-gnu-as
--with-gnu-as --without-newlib --disable-bootstrap --verbose
--enable-threads --enable-languages="c"
--prefix=/rtems/mcoutinho/ri/gcc-without-newlib/prefix
The output of the compilation is the following:
/rtems/mcoutinho/ri/gcc-without-newlib/tools/b-gcc/./gcc/xgcc
-B/rtems/mcoutinho/ri/gcc-without-newlib/tools/b-gcc/./gcc/

So when the flag -DL_fixunssfsi is passed to compile libgcc2.c, the system
will try to find the limits.h file which is part of the newlib, but I don't
want newlib.
I've tried several different configurations and versions of GCC. As far as I
know, versions GCC-3.X work, but GCC-4.X don't :(.
My goal is to have the most basic cross-compiler possible, not dependent on
any system or library that will use it. I also would like not to have to
apply a patch to GCC in order to do this.
Is this possible?
Tools versions:
gcc-4.4.3
binutils-2.20
Many thanks
