I remember very vaguely. IIRC I have a patch for Libtool to deal with
(IOW: rightly ignore) precompiled headers floating around somewhere.
Is it that you're trying to create them, or merely use installed
precompiled headers?
Create them. We're trying to reduce the time to compile our program. I
was hoping there would be a way to add a setting in our Makefile.am or
configure.ac to automatically create .pch files for our headers, and
automatically use them when ocmpiling (I think gcc does this
automatically, if they're generated correctly).
Would it make sense to deal with precompiled headers for GCC only, or
are other compilers interesting as well? For creation, I think this
could very much complicate things, also I think it's not too good an
idea to promote this portability-wise; their mere use should be possible
though (I think it already is, but haven't tested).
We're only interested in gcc. Perhaps it would be appropriate to
ignore the setting if other compilers dont support it.
Thanks
Paul
