I am trying to build uClinux from the CVS archives at opencores.org. I have followed the directions at http://www.opencores.org/tmp/cvsget_cache/or1k/uclinux/uClinux-2.0.x/README.or32 rather closely. A summary and comments follow: # To build toochain follow these steps mkdir /tmp/tools (I'm using /tools/local.uclinux) cd /tmp/tools mkdir or32-uclinux export PATH=/tmp/tools/or32-uclinux/bin:$PATH # # Binutils: # cvs -z9 co or1k/binutils cd or1k mkdir binutils-ucl cd binutils-ucl ../binutils/configure --target=or32-uclinux --prefix=/tmp/tools/or32-uclinux make all install cd ../../ binutils was configured, built, & installed without error. # # Gcc # cvs -z9 co or1k/gcc-3.1 cd or1k mkdir gcc-ucl cd gcc-ucl ../gcc-3.1/configure --target=or32-uclinux --prefix=/tmp/tools/or32-uclinux/ --local-prefix=/tmp/tools/or32-uclinux/or32-uclinux/ --with-gnu-as --with-gnu-ld --verbose --enable-languages=c make all install cd ../../ I originally tried to build with c & c++; that died. I then backed off to "C" only as above and was able to build & install.

Paul, I had build problems with everything sim,gcc and uclinux. but the ATS script work beautifully for me..albeit on Linux. you might wanna give that one a shot. Cheers! Learner --- P Caaret opencores@usd.com> wrote: http://www.opencores.org/tmp/cvsget_cache/or1k/uclinux/uClinux-2.0.x/README.or32
