Building a Solaris cross compiler

["Mark Cuss" <mcuss at cdlsystems dot com>]

Hi All

I'm working on building a Solaris cross compiler on my Linux machine.  I'm
really new to building compilers so please bear with me.  I've looked
through the CrossGCC fact and done some googling but can't seem to make this
work.  Hopefully someone can point me in the right direction.

My host machine is a Pentium 4 box running Red Hat 8.  I'm attempting to
build the cross compiler using the stock RH8 compiler.

I'm using binutils version 2.14 and gcc 3.4.0.

I've cobbled up the following procedure based upon two different howto's
that I've found on the net.  My build environment is set up like this:

Base is ~/cross2
binutils is built in ~/cross2/build-binutils
gcc is built in ~/cross2/build-gcc
everything is installed in ~/cross2/build-install

I've used the following shell file to set up my environment:

export crosssrc=/users/mark/cross2
export host=i686-pc-gnu
export target=sparc-sun-solaris2.9
export prefix=$crosssrc/build-install
export sysroot=$crosssrc/sysroot
export syslibs=$sysroot/usr/lib
export sysincludes=$sysroot/usr/include

I've made my "sysroot" by tarring up /usr/include /usr/ccs/lib /usr/lib and
/lib from my Solaris 9 box.

The procedure - this is what I've tried:

1)  Build bin-utils:
I've configured binutils using the following flags:
--host=$host --target=$target --prefix=$prefix -v

This seems to compile and install into the prefix directory without a
problem.

2)  Build gcc
First, I do this to add the newly compiled binutils to my path:
export PATH=$prefix/sparc-sun-solaris2.9:$PATH

I then configure gcc using the following flags:
--host=$host --target=$target --with-headers=$sysincludes --with-libs=$sysli
bs --with-gnu-ld --with-gnu-as --prefix=$prefix --enable-languages=c,c++,obj
c

The configure fails with these messages:

[mark@cussy1 build-gcc]$
../gcc-3.4.0/configure --prefix=$prefix --target=$target --host=$host --with
-gnu-as --with-gnu-ld --with-libs=$syslibs --with-headers=$sysincludes --ena

*** The command '/usr/bin/gcc -o conftest -O2   conftest.c' failed.
*** You must set the environment variable CC to a working compiler.

The permissions things bugged me - I figured that this was a problem with
permissions on the solaris headers and libs, so I ran this as root.  The
permissions errors vanished, byt the unknown opcodes are still there.

Any ideas?  As far as I know the gcc on the system is fine....  I tried
setting $CC to my compiler /usr/bin/gcc as the message suggested but to no
avail.  If anyone can help me out I'd really appreciate it.

Thanks in advance,

Mark
