Hi, I've run into a problem building the 4.0.0 compilers that I'm hoping you can advise me on. The error is pasted below. Details about my setup: - build was configured in the standard way, i.e. cd gcc-4.0.0; mkdir objdir; cd objdir; ../configure --prefix=..... - I've run into the same problem trying to build the 4.0.0 compilers using both gcc 3.3.2 and 3.4.2. - Linux zambi 2.4.22-1.2199.nptlsmp #1 SMP Wed Aug 4 11:48:29 EDT 2004 i686 i686 i386 GNU/Linux - Fedora Core release 1 (Yarrow) - GNU ld version 2.14.90.0.6 20030820 /local/data/zambi4/irby/gcc-4.0.0/objdir/gcc/xgcc -B/local/data/zambi4/irby/gcc-4.0.0/objdir/gcc/ -B/local/data/zambi4/irby/gcc-4.0.0/i686-pc-linux-gnu/bin/ -B/local/data/zambi4/irby/gcc-4.0.0/i686-pc-linux-gnu/lib/ -isystem /local/data/zambi4/irby/gcc-4.0.0/i686-pc-linux-gnu/include -isystem /local/data/zambi4/irby/gcc-4.0.0/i686-pc-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I/local/data/zambi4/irby/gcc-4.0.0/libmudflap -I. -Wall -ffunction-sections -fdata-sections -O2 -g -O2 -MT mf-runtime.lo -MD -MP -MF .deps/mf-runtime.Tpo -c /local/data/zambi4/irby/gcc-4.0.0/libmudflap/mf-runtime.c -fPIC -DPIC -o .libs/mf-runtime.o /local/data/zambi4/irby/gcc-4.0.0/libmudflap/mf-runtime.c:305: error: redefinition of 'struct option' make[4]: *** [mf-runtime.lo] Error 1 make[4]: Leaving directory `/local/data/zambi4/irby/gcc-4.0.0/objdir/i686-pc-linux-gnu/libmudflap' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/local/data/zambi4/irby/gcc-4.0.0/objdir/i686-pc-linux-gnu/libmudflap' make[2]: *** [all] Error 2 make[2]: Leaving directory `/local/data/zambi4/irby/gcc-4.0.0/objdir/i686-pc-linux-gnu/libmudflap' make[1]: *** [all-target-libmudflap] Error 2 make[1]: Leaving directory `/local/data/zambi4/irby/gcc-4.0.0/objdir' make: *** [bootstrap] Error 2 Thanks for any help!
