Hi Isuru, thank you. I'm recompiling now (after make distclean) and hitting a similar-looking problem: https://dl.dropboxusercontent.com/u/83265276/eclib-20170104.log
Could it be that some parts of the compilation use sage's gcc while others use the system gcc? Is there a way to force them all to use the same gcc?
