I've now spotted the problem here : the libc.so copied over from the target box was actually a script redirecting to /lib/libc.so.6, so after appropriate copies and links, this is sorted. I then hit the problem that powerpc--linux-gnu-ld tells me that crti.o cannot be found, this turned out to be not passing in --with-libs to gcc, so, for helping out any other unfortunate souls as myself in future, he's a nice distilled HOWTO on building a 3.0 ppc crosscompiler to an already existing target system. it should be easily adaptable to other targets. -------------- extract binutils-2.11.92.0.10 into /tmp/work/binutils $ cd /tmp/work $ mkdir build-binutils $ cd build-binutils $ ../binutils/configure --target=powerpc--linux-gnu --prefix=/opt/powerpc $ make $ make install $ export PATH=/opt/powerpc/bin/:$PATH copy in /usr/lib/*.o from target into /opt/powerpc/powerpc--linux-gnu/lib copy in /usr/lib/libm.* from target into /opt/powerpc/powerpc--linux-gnu/lib copy in lastest /lib/* from target into /opt/powerpc/powerpc--linux-gnu/lib attempt to preserve symbolic links! link libc.so.6 to libc.so copy in /lib/ld.so.1 from target into /opt/powerpc/powerpc--linux-gnu/lib copy in /usr/include from target into /opt/powerpc/powerpc--linux-gnu/lib extract gcc-3.0.2 source into /tmp/work/gcc $ cd /tmp/work $ mkdir build-gcc $ cd build-gcc $ ../gcc/configure --target=powerpc--linux-gnu --prefix=/opt/powerpc \ --enable-languages=c,c++ --enable-threads=posix --with-libs="/opt/powerpc/power pc--linkux-gnu/lib" $ make $ make install ------------------ > I'm building a i686-pc-linux-gnu to powerpc--linux-gnu cross compiler with > gcc-3.0.2 > using --prefix=/opt/powerpc for both binutils and gcc > binutil had built sucessfully > I've copied the libs and includes over from my target platform into > /opt/powerpc/powerpc--linux-gnu/ > > i've configured gcc with > --target=powerpc--linux-gnu --prefix=/opt/powerpc \ > --enable-languages=c,c++ --enable-threads=posix > > when the make of the cross compiler gets up to using xgcc to link libgcc_s.so, > it picks up my systems /lib/libc.so.6 and understandably fails. > > Has anyone any idea why it would be picking up this libc rather than > /opt/powerpc/powerpc--linux-gnu/lib/libc.so.6 ? > > alternatively, does anyone know what the decision logic is for where > xgcc looks > for libraries, and where this happens in the source, then I at least have a > fighting chance of fixing this myself :) > > Thanks, > Rob Taylor > > > ------ > Want more information?
