[Bug bootstrap/23231] New: cross compiling fails for mips-sgi-irix6.5

[pfl at iis dot fhg dot de]

when cross compiling the gcc 4.0.2 on a i686-pc-linux-gnu with
intel: binutils 2.16.1 - compiled with gcc 4.1.0
mips:  binutils 2.16.1 - compiled with gcc 4.1.0

the following error occures:

/home/pfl/gnu/mips-sgi-irix6.5/bin/ld: unrecognized option '-_SYSTYPE_SVR4'
/home/pfl/gnu/mips-sgi-irix6.5/bin/ld: use the --help option for usage 
information
collect2: ld returned 1 exit status

and the compilation exits. 

The same problem occures when the binutils are:
intel: binutils 2.16.1 - compiled with gcc 4.0.2
mips:  binutils 2.16.1 - compiled with gcc 4.0.2

I get also the same problem when compiling on an apple mac - tiger 10.4.2.

Hmm cross64.h is being used for crosses, why I don't know.  That should be only used for crosses 
which are on IRIX.

You need to add a --with-gnu-ld configure option.

GNU ld and Irix ld have incompatible options, and the toolchain naturally
defaults to assuming irix ld options, so you must specify GNU ld at configure
time for a binutils using cross.

It is possible that you may still run into problems.  I don't know how good the
irix6 support is in the GNU linker.  It probably doesn't support all of the
features of the native linker.

The cross64.h file has nothing to do with this.  The file is no longer used and
should be deleted.  I'll take care of that.

I tried your suggestions with the following parameters:

I compilied with gcc-4.0.2 binutils 2.16.1 with:
CC="ccache i686-pc-linux-gnu-gcc-4.0" CXX="ccache i686-pc-linux-gnu-g++-4.0" 
CFLAGS="-O1" CXXFLAGS="-O1" configure --cache-file=../binutils_configure-i686.
cache --prefix=/home/pfl/gnu --bindir=/home/pfl/gnu/bin --sbindir=/home/pfl/gnu/
sbin --libdir=/home/pfl/gnu/lib32  --program-prefix=i686-pc-linux-gnu-

Then I compiled gcc-4.0.2 with:
CC="ccache i686-pc-linux-gnu-gcc-4.0" CXX="ccache i686-pc-linux-gnu-g++-4.0" 
CFLAGS="-O1" CXXFLAGS="-O1"  ../gcc-4.0-20050728/configure --cache-file=../
gcc40_configure-mips.cache --prefix=/home/pfl/gnu --bindir=/home/pfl/gnu/bin --
sbindir=/home/pfl/gnu/sbin --libdir=/home/pfl/gnu/lib32 --disable-nls --disable-
multilib --disable-intl --enable-languages=c,c++ --target=mips-sgi-irix6.5 --
program-prefix=mips-sgi-irix6.5- --without-headers --with-newlib --with-gnu-ld -
-with-ld=/home/pfl/gnu/bin/mips-sgi-irix6.5-ld --with-gnu-as --with-as=/home/
pfl/gnu/bin/mips-pc-linux-gnu-as

This leads to:
...
/home/pfl/gnu/mips-sgi-irix6.5/bin/ld: cannot find -lc
collect2: ld returned 1 exit status
...

Then I tried:
CC="ccache i686-pc-linux-gnu-gcc-4.0" CXX="ccache i686-pc-linux-gnu-g++-4.0" 
CFLAGS="-O1" CXXFLAGS="-O1"  ../gcc-4.0-20050728/configure --cache-file=../
gcc40_configure-mips.cache --prefix=/home/pfl/gnu --bindir=/home/pfl/gnu/bin --
sbindir=/home/pfl/gnu/sbin --libdir=/home/pfl/gnu/lib32 --disable-nls --disable-
multilib --disable-intl --enable-languages=c,c++ --target=mips-sgi-irix6.5 --
program-prefix=mips-sgi-irix6.5- --without-headers --with-newlib --with-gnu-ld

Which broke at the same line with:
...
/home/pfl/gnu/mips-sgi-irix6.5/bin/ld: cannot find -lc
collect2: ld returned 1 exit status
make[2]: *** [libgcc_s.so] Fehler 1
make[2]: Verlassen des Verzeichnisses Verzeichnis »/home/pfl/gnu/build/mips-gcc-
4.0/gcc«
make[1]: *** [stmp-multilib] Fehler 2
rm gfdl.pod gcov.pod cpp.pod gpl.pod gcc.pod fsf-funding.pod
make[1]: Verlassen des Verzeichnisses Verzeichnis »/home/pfl/gnu/build/mips-gcc-
4.0/gcc«
make: *** [all-gcc] Fehler 2

If I manualy executed the line without -lc the line compiles/links. But the make 
file tries to redo this step so I find myself in an endless loop of manual 
compiling/linking and starting make.

I think the -lc linker switch could perhaps be removed from the Makefile.
I have a coupel of very fast machines and I am willing to try some parameter 
constellations for you if you like.

(In reply to comment #3)
> I tried your suggestions with the following parameters:

No -lc is needed.  Did you copy the libraries and headers from the IRIX box as you need both to get a 
working cross compiler.

You might want to use --with-sysroot to make it easier for you.
