Hi there, Currently, I am using GCC.4.2.1 on Ubuntu 6.06. And I have recently installed GCC and it all works fine including compiling and make. However, when I want to re compile and make in the Build folder created as part of GCC, the below error seen:- i) When I executed "make bootstrap" make[3]: Entering directory `/home/jason/local/gcc/build/gcc' mawk -f ../../gcc-4.2.1/gcc/opt-functions.awk -f ../../gcc-4.2.1/gcc/opth-gen.awk \ < optionlist > tmp-options.h /bin/sh: optionlist: No such file or directory make[3]: *** [s-options-h] Error 1 make[3]: Leaving directory `/home/jason/local/gcc/build/gcc' make[2]: *** [all-stage1-gcc] Error 2 make[2]: Leaving directory `/home/jason/local/gcc/build' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/home/jason/local/gcc/build' make: *** [bootstrap] Error 2 ii) When I executed "make install" cc1: error: unrecognized command line option "-Wno-overlength-strings" make[2]: *** [fixincl.o] Error 1 make[2]: Leaving directory `/home/jason/local/gcc/build/fixincludes' make[1]: *** [install-fixincludes] Error 2 make[1]: Leaving directory `/home/jason/local/gcc/build' make: *** [install] Error 2 Please advise as I have been stuck and couldnt do anything. I tried to find more info from the past forums yet it couldnt help. Thanks. Regards, Jason
