cross compiler for MIPS problems

cross compiler for MIPS problems

[filipe.pereira]

Dear all,

I'm trying to build a mips cross compiler on a sparc-sun-solaris2.7 hos=
t.
I am using binutils 2.10.1, gcc 2.95.2 and newlib 1.9.0.
I used the following to configure/build:

BINUTILS:
../binutils-2.10.1/configure --host=3Dsparc-sun-solaris2.7 --prefix=3D/=
home/pereira/mips/binutils --target=3Dmips
make all install

GCC:
../gcc-2.95.2/configure --target=3Dmips --prefix=3D/home/pereira/mips/b=
inutils --enable-languages=3Dc=20
	--with-newlib --with-headers=3D/home/pereira/gcc/newlib/libc/include/
make=20
make install


I've been able to configure/build/install both binutils and gcc but, wh=
en I try to configure newlib, the ld acuses the missing "crt0.o" file. =
Since I have a MIPS machine, I downloaded the crt0.o file from there (j=
ust as GCC CROSS FAQ advices) but now I=20
get the following error:

Configuring for a sparc-sun-solaris2.7 host.
Created "Makefile" in /home/pereira/install_programs/build-newlib using=

 `_start':

*** The command '/home/pereira/mips/binutils/mips/bin/gcc -o conftest -=
g -O2   conftest.c' failed.
*** You must set the environment variable CC to a working compiler.

The question now is if I should or not use that crt0.o... It looks like=
 it is different from what I want, and therefor I should not use that o=
ne. In that case, have I done=20
something wrong? Should I have my crt0.o file automatically generated?
About the error in libgcc.a: is the library not correctly built? Have I=
 done something wrong?

Thanks in advance,
FIlipe Pereira

No surprise; it is newlib that is supposed to generate this file.  In
which stage of the execution of `configure' does it complain about the
lack of crt0.o?
