For my project, I’ve noticed very long compile times for the 2013 version of the compiler (compared to the 2011 version). Files that used to take seconds are now taking minutes to compile. Has anyone else noticed this? It is consistent for updates 0,1,2 (and also on Linux). I’ve got a fairly complicated project (a few hundred modules, split into several libraries and one main program), and am using a lot of the newer object oriented stuff. I notice that the low level files (old style f77 code, the library modules, etc.) compile as fast as before. However, once it gets to the main program where there are a lot of dependencies on the low-level modules, it slows to a crawl. I suspected that the compiler is performing an extraordinary amount of code optimization, but the problem persists with debug builds where all the optimization is turned off. Any ideas?
