(I've snipped the instructions so this won't be terribly long)

I have the following installed on a RedHat 7.0, kernel 2.2.16-22, i586:

/usr/local/src/binutils-2.11.2
/usr/local/src/build-binutils
/usr/local/src/build-gcc
/usr/local/src/gcc-3.0.2
/usr/local/src/newlib-1.9.0


I configured/made binutils as follows:

../binutils-2.11.2/configure --target=mipsel-linux -v
make all install

and then I made the following links:

cd /usr/local/mipsel-linux/
mkdir sys-include
ln -s sys-include include
chmod o+w sys-include
cd /usr/local/lib
ls
mkdir -p gcc-lib/mipsel-linux
chmod o+w gcc-lib/mipsel-linux

I configured/tried to make gcc as follows:

/usr/local/src/gcc-3.0.2/configure --target=mipsel-linux --with-newlib 
--with-headers=/usr/local/src/newlib-1.9.0/newlib/libc/include 
--enable-static --disable-shared

make all

I've attached the make errors at the end of this message.  Can anyone tell 
if this is some kind of missing link to an include file problem like what 
you've dealt with?  If it is, how can I fix it?  Has anyone out there made a 
cross compiler for mipsel-linux?  If so, can you tell me how you did it?

Thanks

Mark
