A big thanks Waldek. I seem to have a gpc built with gcc 3.4.2. Just a few minor hiccups which don't appear to have been too critical: 1) The man pages didn't build because help2man wasn't found. I'm not sure where this normally comes from, but the man pages have usually been built ok. 2) When I did 'cd gcc' and 'make pascal.install-with-gcc' , the gpc -v command gave me the correct build version, but a gpc compilation resulted in the error 'installation problem, cannot exec gpc1: no such file or directory'. Repeating the installation just using 'make install' solved the problem. 3) At the end of the install, I get the error /bin/sh: -ranlib: command not found. I presume the leading '-' is messing this up. I found ranlib in /usr/bin. Apologies for the corporate nonsense that follows. I'll try to get our company policy changed but it's likely to be a David and Goliath battle! Regards David.

I'm trying to compile gpc-20040516 with gcc-core-3.4.2 in the hope it will sort out a compatibility problem when linked with other c-code we've built. I found Waldek's patches to gpc proper and gcc 3.4.20041015 (I've also tried the 3.4.0 patch) and applied these using $ patch -p1 < XX.diff in the respective source directories. However, the make crashes, firstly with

../../gcc-3.4.2/gcc/p/mk_lang_opt: Permission denied.

In normal build `mk_lang_opt' should not run (it is needed only after a modification). The problem is due to limitation of `patch' (inabilty to set file mode or modification time) and microsecond timestamps in new kernels. Before the build you should touch `lang.opt' and `handle-opts.c' to mark them as up to date.

...

So I do a chmod +x on this file and type make again. The next worry comes when it says I should have 16 shift/reduce conflicts and 30 reduce/reduce conflicts but I get 16 and 295!

That is harmless.

...

The final nail in the coffin appears when p/handle-opts.c produces a string of errors because the OPT_* components are undeclared. Just before this, lang.c reports a number of warnings about function declarations not being prototypes and no previous prototype for 'pascal_post-options' or 'pascal_handle_option'.

Trying to run `mk_lang_opt' had wiped-out pre-built `lang.opt' (you get empty file instead). `lang.opt' is needed to define `OPT_*' constants. Making `mk_lang_opt' executable _before_ the build should also correct the problem.
