Darrell, Slavek, Michele, Fancios, All, Does anybody have a list of automake packages that build/support --enable-final configure option. I haven't saved all configure file options -- yet, but before I start I thought I would check and see if anyone had a list? Apparently there are optimization opportunities provided when --enable-final is used, but there is a downside to using it if you are building on a build-farm. I would like to experiment with it, but before undertaking the effort, I thought I would ask if anyone has already done something like this? There are only scattered references to this configure option, but I was able to find a KDE related explanation: --enable-final makes the build system concatenate all sourcefiles in a directory (say, Konqueror's sourcefiles) into one big file. Technically, this is achieved by creating a dummy file which simply includes every C++ sourcefile. The advantage of this is that the compile a- takes less time since there is only little scattered file opening involved and b- produces usually more optimized code, since the compiler can see more code at once and thus there are more chances to optimize. Of course this eats a lot more memory, but that is not an issue nowadays. Now, it's clear why this makes distcc useless: there is just one huge file per project, and outsourcing that file via distcc to other nodes will just delay the build since the sourcecode (and it's a lot) has to be transferred over the network, and there is no way to pararellize this. see: https://distcc.googlecode.com/svn/trunk/doc/web/faq.html -- David C.
