I use Gentoo 2004.1 default bison :

bison -V bison (GNU Bison) 1.875

gpc needs bison 1.875c. I have added pregenerated parser files to the Web page for people with older bison.

There is lang.opt file with 0 Byte size in gcc-3.4-20040702/gcc/p folder.

Mk_lang_opt has no executable flag. I ran tar xzf to unpack gpc archive an diffs to gpc and gcc.

If I set executable flag to mk_lang_opt file, build process continues.

I had never unpack gpc tarball with p option, like tar xzpf gpc-20040516.tar.gz and build process always works fine.

I can see that mk_lang_opt comes from update27h.diff, so tar xzpf to gpc tarball is not needed. ../../gcc-3.4-20040702/gcc/p/mk_lang_opt < ../../gcc-3.4-20040702/gcc/p/opts.sum > "../../gcc-3.4-20040702/gcc/p/lang.opt" /bin/sh: line 1: ../../gcc-3.4-20040702/gcc/p/mk_lang_opt: P??stup odm?tnut make[2]: *** [../../gcc-3.4-20040702/gcc/p/lang.opt] Error 126 make[2]: Leaving directory `/home/dave2/gcc/gcc-3.4/gcc' make[1]: *** [stage1_build] Error 2 make[1]: Leaving directory `/home/dave2/gcc/gcc-3.4/gcc' make: *** [bootstrap] Error 2

Existing file was truncated by redirection.

I don`t now if patch can set executable flag to mk_lang_opt file but I think that not.

Is executable flag really on mk_lang_opt file needed to bootstrap compiler or I am doing some error ?

The patch contains up to date 'lang.opt'. I suspect that some timestamp weirdness is causing rebuild. Hmm, smells like nanosecond timestamps -- probably patch creates 'mk_lang_opt' few microseconds later then 'lang.opt'. The executable flag is needed when source is changed.
