Folks, I've dug through the archives to see if my question is answered here but haven't found anything. I've been scouring Google for the past few days and am coming to you for help after having exhausted the resources at my disposal. Without further ado, here's what I have: My system: SunOS archive 5.11 oi_151a i86pc i386 i86pc isainfo -kv reports a 64bit OS: 64-bit amd64 kernel modules System compiler: gcc (GCC) 3.4.3 (csl-sol210-3_4-20050802) Libraries I'm using to compile gcc-4.7.0: gmp-5.0.5 mpfr-3.0.1 (mpfr-3.1.0 crashed earlier than where I am) mpc-0.9 binutils-2.22 I'm attempting to do a full bootstrap compilation so I can get rid of the system compiler. I've followed the instructions here: http://stackoverflow.com/a/6228588 to setup and build gcc using the libraries mentioned above. I'm building as per gcc recommendations in a build directory parallel to the gcc-4.7.0 sources. My environment has the following variables: ABI=long and the configure command I used to kickstart this build is: ../gcc-4.7.0/configure --prefix=/usr/local/gcc --enable-bootstrap --with-gnu-as --with-gnu-ld I've also tried it out without the "gnu-as" and "gnu-ld" lines but get the same result which might be telling. Compiling fails with the error message shown in this paste bin: http://pastebin.com/t2DAjFQn As I said I'm at my wit's end at this time. I thought for sure the "with-gnu-ld" and "with-gnu-as" would solve this but it hasn't and removing those bits doesn't change where the build breaks or the error message. I can provide any additional information (files, output, etc) as needed. Any help would be appreciated. Thanks! Shahbaz Javeed Blog: http://learnonthejob.blogspot.com/
