I've been trying for the past couple of days to cross-compile a Sparc version
of gcc/tools on a FreeBSD system. While a number of things have gone right,
I'm getting hung up on one error that I can't seem to fix on my own. I'm not
on the list, so please at least cc me when you reply.

The problem manifests itself when I'm compiling gcc. Below is the last 20 or
so lines of the output.

configure: error: installation or configuration problem: C compiler cannot create executables.
*** Error code 1

Stop.


I figured that in order to narrow down the problem, I'd try running the
command by hand, and got:

bash-2.03# /usr/tmp/cross/build/gcc/xgcc -B/usr/tmp/cross/build/gcc/ -B/usr/local/cross/sparc/sparc-sun-solaris2.1.5/bin/ -g
xgcc: No input files

Ok. Fair enough. Lets give it one.

bash-2.03# cat > hello.c
#include <stdio.h>
void main(void)
  {
  }

And run it again....

bash-2.03# /usr/tmp/cross/build/gcc/xgcc -B/usr/tmp/cross/build/gcc/ -B/usr/local/cross/sparc/sparc-sun-solaris2.1.5/bin/ -g -o hello hello.c
hello.c: In function `main':
hello.c:3: warning: return type of `main' is not `int'
/usr/tmp/cross/build/gcc/collect-ld:built in linker script:1: parse error
collect2: ld returned 1 exit status

Ok. The warning makes sense. However, it looks like its ld thats barfing.

Doing a which ld, I found it was trying to use the system (FreeBSD) linker. So,
I added the path to the bintuils I had installed already, and reran it. This
time, I got:

 /usr/tmp/cross/gcc-2.95.2/gcc/xgcc -B/usr/tmp/cross/gcc-2.95.2/gcc/ -B/usr/local/cross/sparc/sparc-sun-solaris2.5.1/bin/ -g -O2 -o hello hello.c
/usr/local/cross/sparc/sparc-sun-solaris2.5.1/bin/ld: cannot open values-Xa.o: No such file or directory
collect2: ld returned 1 exit status

I did not find the file values-Xa.o anywhere on the disk.

At this point, I'm completley confused. My configure line is as follows:


prefix=/usr/local/cross/sparc
target=sparc-sun-solaris2.5.1
i=$prefix/bin

configure --target=$target --prefix=$prefix \
	--with-headers="/usr/tmp/cross/include" \
	--with-libs="/usr/tmp/cross/lib" \
	--enable-threads --with-gnu-ld --with-gnu-as -v

Any hints would be valuable. A clue as to what I'm doing wrong would be a plus,
as I'll have to do the same for HP/UX and AIX once this is working...
