Problem Building Cross Compiler - gcc2.95.2 hppa1.1-hp-hpux10.20 and sparc-sun-solaris

[Steve Fosdick <steve.fosdick@aom.bt.co.uk>]

I am trying to build a cross compiler that is to run on an HP machine with an HP-PA processor running HP-UX, and generate code for a Sun machine with Sparc processor running Solaris 7.

Here's how I configured it.

mkdir gcc-obj
cd gcc-obj
../gcc-2.95.2/configure --prefix=/opt/gnu --target=sparc-sun-solaris --enable-shared --enable-haifa --with-gnu-as --with-gnu-ld --with-headers=/home/fosdicsj/software/unix/build/sparc-sun-solaris/sun-includes --with-libs=/home/fosdicsj/software/unix/build/sparc-sun-solaris/sun-libs

To start with it fails to compiler gmon-sol2.c.  Here's an excerpt from the log:

/home/fosdicsj/software/unix/build/sparc-sun-solaris/gcc-obj/gcc/xgcc -B/home/fosdicsj/software/unix/build/sparc-sun-solaris/gcc-obj/gcc/ -B/opt/gnu/sparc-sun-solaris/bin/ -I/opt/gnu/sparc-sun-solaris/include -DCROSS_COMPILE -DIN_GCC -DHAIFA    -O3 -I./include  -I. -I../../gcc-2.95.2/gcc -I../../gcc-2.95.2/gcc/config -I../../gcc-2.95.2/gcc/../include  \

../../gcc-2.95.2/gcc/config/sparc/gmon-sol2.c:184: (Each undeclared identifier is reported only once
../../gcc-2.95.2/gcc/config/sparc/gmon-sol2.c:184: for each function it appears in.)

make: *** [all-gcc] Error 2
zsh: 20319 exit 2     make

I "fixed" this by adding a #define for PATH_MAX to gmon-sol2.c (#include <limits.h> doesn't work) and then it gets further.  Here's another log file excerpt:

A look at the log from configure reveals more info:

collect2: ld returned 1 exit status
configure: failed program was:

#line 1760 "configure"
#include "confdefs.h"

main(){return(0);}

So, can anyone please offer me any help on getting it to finish compiling.  I have no idea what this values-Xa.o file does or where it should come from.

The same version of gcc (2.95.2) compiles flawlessly as a native compiler and gcc2.8.1 compiled OK as a cross compiler for Sparc.
