Hi, Any one have any idea why I am getting the following error exit? /usr/local/bin/gcc -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -DHAVE_CONFIG_H -DGENERATOR_FILE -o build/genattrtab \ build/genattrtab.o build/genautomata.o \ build/rtl.o build/read-rtl.o build/ggc-none.o build/min-insn-modes.o build/gensupport.o build/insn-conditions.o build/print-rtl.o build/errors.o \ build/varray.o ../build-powerpc-ibm-aix5.1.0.0/libiberty/libiberty.a -lm build/genattrtab /tmp/GCC/Source/gcc-4.0.1/gcc/config/rs6000/rs6000.md > tmp-attrtab.c out of memory allocating 80016 bytes after a total of 4161652476 bytes make[2]: *** [s-attrtab] Error 1 make[2]: Leaving directory `/tmp/GCC/Source/BuildDir/gcc' make[1]: *** [stage1_build] Error 2 make[1]: Leaving directory `/tmp/GCC/Source/BuildDir/gcc' make: *** [bootstrap] Error 2 I have tried running "make" over 6 times and keep getting this message. I have no idea what is going on. As far as I can tell I have unlimited stack space and such. I am running this build as root. I am using the following "configure" and "make" calls. I have altered the configure calling parameters with no change in the end result. My last attempt was to add the line beginning --with-cpu... in the configure and by removing -lean from the bootstrap parameter in the make. /tmp/GCC/Source/gcc-4.0.1/configure --disable-nls --with-libiconv-prefix=/usr \ --enable-language=c,c++,f95,objc --disable-shared --disable-multilib --enable-threads=aix \ --with-cpu=power4 --with-system-zlib make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap-lean Bye, Dwight
