Somebody in the thread at some point said: >> checking for gcc... gcc >> checking for C compiler default output file name... a.out >> checking whether the C compiler works... configure: error: cannot run C > You errored out because you do not have a C compiler on your > computer. This is weird and something you can fix. I think in that case the two tests prior to that would have failed. He needs to look towards the end, but perhaps not right at the end, of his config.log to find the actual error where it tries to run gcc. The bit he quoted so far is not the relevant bit. -Andy
