Here's what I did for setup: (1) I compiled GMP, MPFR, and MPC. As far as I can tell, all the libs created are 64-bit. (2) set LD_LIBRARY_PATH=/home/smith/GMP/lib:/home/smith/MPFR/lib:/home/smith/MPC/lib: (3) ./configure --prefix=/home/smith/GCC461 --with-gmp=/home/smith/GMP --with-mpfr=/home/smith/mpfr --with-mpc=/home/smith/mpc gmake but the -m32's are creeping in somehow. --Steve ----- Original Message ----- From: Jonathan Wakely <jwakely.gcc@xxxxxxxxx> To: steve kirby <thin_runner@xxxxxxxxx> Cc: GCC HELP <gcc-help@xxxxxxxxxxx> Sent: Tuesday, October 25, 2011 3:13 PM Subject: Re: gcc 4.6.1 compile fails in linking stage - libgmp.so in wrong format On 25 October 2011 22:09, steve kirby wrote: > Hi, > > here's the error I see in the GCC linking phase: > > > libtool: link: /home/smith/gcc-4.6.1/host-x86_64-unknown-linux-gnu/gcc/xgcc -B/home/smith/gcc-4.6.1/host-x86_64-unknown-linux-gnu/gcc/ -B/home/smith/GCC461/x86_64-unknown-linux-gnu/bin/ -B/home/smith/GCC461/x86_64-unknown-linux-gnu/lib/ -isystem /home/smith/GCC461/x86_64-unknown-linux-gnu/include -isystem /home/smith/GCC461/x86_64-unknown-linux-gnu/sys-include -m32 -shared .libs/gnu_java_math_GMP.o ../../../native/jni/classpath/.libs/jcl.o -Wl,-rpath -Wl,/home/smith/GMP/lib -Wl,-rpath -Wl,/home/smith/GMP/lib -L/home/smith/GMP/lib /home/smith/GMP/lib/libgmp.so -m32 -m32 -m32 -Wl,-soname -Wl,libjavamath.so -o .libs/libjavamath.so > /home/smith/GMP/lib/libgmp.so: could not read symbols: File in wrong format > collect2: ld returned 1 exit status > > I checked the file that libgmp.so is sym. linked to and it is 64-bit. Is my problem here the -m32's? Yes. > If so, can anyone please clue me in on how to make them -m64. It looks as though you're linking a 32-bit lib, so you don't want to make them -m64 > If -m32 isn't the problem, please let me know what is. It is the problem, but it's hard to know why it's happened because you didn't say how you configured GCC.
