fortranstubs,etags are common data for all builds. In case of multiple builds one after another - it was ok to just rebuild each time. With parallel builds - it doesn't make sense to rebuild fortranstubs, etags parallely. Perhaps we need some kind of locking mechanism? The first configure cleates a lock - before starting a build and removes after completion. If a subsequent configure comes to the state fo building etags [or fortranstubs] - it checks the lock - and if it exists - skips the build? Satish On Sat, 26 Mar 2011, Jed Brown wrote:

Can temporary files be put in a private directory so that multiple reconfigures can be run simultaneously? I think the rest of configure works.
