Hi all,

When compiling ROOT v5.17/05 (CVS) with icc 10.0 on a system running Mandriva 2008, I got the following error message:

Compiling and installing with gcc 4.2.2 went smooth.

Hi Pieter,
could you try this patch:

  [/code] Just save it to a file (“afile.txt”) and run “patch -p0 < afile.txt” and then try make again. Does that help?

Cheers, Axel.

Hi Axel,

Thanks for your reply. After applying your path, I tried to recompile and got a different error message:

Hi,

OK, so ROOT is fixed, now you’ll have to talk to Intel to get their compiler fixed It looks like a compiler error to me, and from what I’ve heard they are extremely helpful and fast with their response. Uh, in fact this bug has been reported here already: root.cern.ch/phpBB2/viewtopic.php?t=5118 but it seems it has not been reported to Intel yet. Good luck!

Cheers, Axel.

Hi,

I had a look at this post: http://root.cern.ch/phpBB2/viewtopic.php?t=5118. I made the following change in config/Makefile.config: ENABLEPCH := no, as was suggested by ardashev. This has solved my problem.

I will report the issue to Intel. Thanks for your help,
Pieter

The error I reported occured with icc 10.0.023. Before posting the bug to Intel, I upgraded my compiler to their newest version 10.0.026. Apparently, someone has already bumped into the problem, because the issue is solved. ROOT v5.17/05 compiles and runs perfectly.

Thanks again,
Pieter
