I end up control-C-ing it. If I run again using make -j1, it states that the build was successfull:
=== ROOT BUILD SUCCESSFUL. ===
=== Run ‘source bin/thisroot.[c]sh’ before starting ROOT ===
But if I try again with make -j8 it hangs again. Not sure what’s going on. When I run root, it overall
seems to run fine, however there are some strange elements of behavior that I haven’t seen before.
No, this is a unique failure… It must be something in your environment.
I’d suggest to do the following once the build hangs:
ps -feH |less
look for make, and you’ll see its sub processes enuerated below. The culprit, the one causing the build to hang, will be the sub process without children. If this doesn’t make sense / doesn’t help please post the output of that command, everything including and below “make”.
Weird. I only ever saw make itself eating 100% on cygwin (with weird error messages included) - likely because some of their patches broke it. Other than that it always behaved nicely. So please do post the ps tree if this happens again.
