ROOT 6 Build From Source Error on Ubuntu 14.04 LTS

@feickert

I find this very confusing, as I don’t see why the number of jobs launched with make should determine if it fails or succeeds. Do you understand this?

Lol… This is ROOT in pure state xD. No idea. Time to submit a bug report…

That was also the reason why it worked for me just “some times”, but I did not find the right reason.

@feickert

Regardless, thank you both for your time and help in getting me a working version of ROOT6 again.

You are welcome

For the working build:

@Pepe Le Pew

So it seems that it is a clear problem in ROOT building procedure (missing dependencies somewhere which is clearly visible if one makes it using a single cpu).

Okay, so (obvious high ignorance on my end) is this an actual bug then, or is this some pathological effect of my Ubuntu’s setup?

BTW. You should try: ls -p interpreter/llvm/src/tools/clang/include/clang/ which should return something like this (for ROOT 6.06/06): AST/ CMakeFiles/ Config/ Makefile Sema/ Basic/ cmake_install.cmake Driver/ Parse/ Serialization/[/quote]
yields

AST/    CMakeFiles/          Config/  Makefile  Sema/           StaticAnalyzer/
Basic/  cmake_install.cmake  Driver/  Parse/    Serialization/

@Pepe Le Pew

and then: ls -p interpreter/llvm/src/tools/clang/include/clang/Driver/ which gives: CMakeFiles/ cmake_install.cmake Makefile Options.inc Options.inc.tmp

yields what you have printed above.

What you show for the “working build” is fine.
But what do you get for the “broken / 1 cpu make” build (after it dies)?

Hi,

I have created sft.its.cern.ch/jira/browse/ROOT-8392 for this.

Thanks for reporting the problem. We didn’t see it because we always build with -jN on the nightlies. A fix has been committed to master and 6.08 branches.
