I have been trying to compile gcc-4.4.1 on my Mac Pro with 64bit Xeon processor with no success. I have the following variables set CFLAGS='-m64' CXXFLAGS='-m64' and I have run ./configure without any command-line options. When I run make, everything runs smoothly for awhile then I get the error copied below. Can someone help me identify what is wrong? Thanks, Jeremy /usr/local/bin/gcc -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual -Wold-style-definition -Wc++-compat -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE -o build/genchecksum \ build/genchecksum.o ../../build-i386-apple-darwin9.8.0/libiberty/libiberty.a ld warning: in ../../build-i386-apple-darwin9.8.0/libiberty/libiberty.a, file is not of required architecture Undefined symbols: "_md5_stream", referenced from: _dosum in genchecksum.o "_fopen_unlocked", referenced from: _dosum in genchecksum.o "_xstrerror", referenced from: _dosum in genchecksum.o _dosum in genchecksum.o _dosum in genchecksum.o ld: symbol(s) not found collect2: ld returned 1 exit status
