RE: [HACKERS] Re: Problems compiling version 7

This reminds me of a problem I once had.

I was trying to "make" the documentation, but zcat kept failing because the
Solaris version does not work the same as the GNU version.  So I installed
the GNU zcat, ran configure again, but still make was failing because of
zcat...

I found that once configure has found an item it is looking for, it caches
it in config.cache.  From then on, even if you do a "make clean", configure
still uses things from config.cache.

To have configure essentially start from scratch and "re-find" things, you
must run "make distclean", which will also delete config.cache.  After doing
this, and running configure again, everything worked fine.

Hope this helps,

Ah, I see. Substituting into source files directly from configure ... very
evil...

(Before you ask why: What if I change Gen_fmgrtab.sh.in, do I have to
re-configure?)

Unfortunately he cut off the line where it says `checking for tr'.
