Dear All, I'm trying to build gcc 4.1.2 on Mac OSX 10.4 and I get an error: gcc -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Wmissing-format-attribute -DHAVE_CONFIG_H -DGENERATOR_FILE -o build/gengtype \ build/gengtype.o build/gengtype-lex.o build/gengtype-yacc.o \ build/errors.o ../build-i386-apple-darwin8.8.1/libiberty/libiberty.a build/gengtype ./input.h: No such file or directory make[2]: *** [s-gtype] Error 1 make[1]: *** [all-gcc] Error 2 make: *** [all] Error 2 My machine type is i386-apple-darwin8.8.1, and the gcc already installed is gcc version 4.0.1 (Apple Computer, Inc. build 5367), make is GNU Make 3.80 My directories are set up like this iMac:~/gnuproject peterhull$ tar -jxf ~/Desktop/gcc-4.1.2.tar.bz2 iMac:~/gnuproject peterhull$ mkdir build iMac:~/gnuproject peterhull$ cd build iMac:~/gnuproject/build peterhull$ ../gcc-4.1.2/configure && make I've looked on Google and this ML but I can't find anything related. It looks like gengtype is looking in the wrong place, as input.h is present, it's in ./gcc-4.1.2/gcc/ Can anyone help? Thanks, Peter
