Actually, #6 has been doing incremental builds for a while and seems to do fine, so #6 is already often pretty fast as it is.
these precompiled_foo.hxx used to be checked in and essentially manually maintained, and a lot of them were actually empty - do we have some plan how to automate maintenance of these headers?
Attached is what I have so far.
one option would be to generated that from the generated object dependency makefiles... but probably that isn't going to be simple because of "special" headers that need to be included in particular order or with particular #define before and #undef after...
I'd consider those to be mostly broken, and if it can't be helped for some reason, they can be blacklisted.
another way is to grep through the cxx files... but there the problem is #ifdefs around #include.
That can hopefully be sufficiently handled in some way too.
,,, is there some pre-existing tool to generate the PCH input headers?
http://gamesfromwithin.com/the-care-and-feeding-of-pre-compiled-headers has something using gcc -H / msvc -showIncludes output , but I think I'll go with my script based on parsing the .cxx files instead. -- Lubos Lunak l.lunak@suse.cz
