We've used tools like ccache and distcc to good effect on NetBSD, probably halving our average compile times on a code base of a million lines or so. I'm not sure if you can use those under Windows or not, but Linux should support them. NB. distcc allows distributed compilation if you have a few free machines lying around, and ccache caches object files based on a hash of the preprocessed source to reduce unnecesasry recompilation (useful if you do a lot of make cleans). They both improve compilation speed but not linking. ----- Original Message ----- From: "Vishnu Mahadevan Menon" <vishnu_m_menon@xxxxxxxxx> To: <gcc-help@xxxxxxxxxxx> Sent: Thursday, March 24, 2005 12:10 PM Subject: Speeding up compiling and linking > Hello all. > > The application I'm working on is of a decent size - > nearly 0.5 million lines of C++ code - and compiling > and linking is simply a *pain*.
