 Those are probably the most labor-intensive ways that you can do it.  It's 
 usually easier to just pass --without-mpicc to configure and use the 
 normal build process in all other respects.
 
 1. No documentation: no mention of MPI in README*, no explicit list of 
 packages
   that might be eligible for --without-*, etc.
 
 2. The default -with-mpicc does not work (it fails to detect the unusable
   state on the original poster's machine), so the override --without-mpicc
   should be regarded with suspicion.

I didn't mean it as any kind of personal slight, and I completely agree that 
this is both under-documented and slightly buggy.  I just wanted to get the 
easiest solution that I know actually works into the mail archives.

I've got ~1/2 of a patch to fix the mpicc detection already written that has 
been shelved for a while, perhaps I should resume work on it.  If I can get 
that working then none of these solutions should be necessary.

[Valgrind-users] Using setrlimit within memcheck

2011-05-24 Thread Scott Kuhn 
Hi,
 
While running a program within the memcheck tool, the code calls
setrlimit to increase the number of file descriptors available:
 
rl.rlim_cur = 65535;
rl.rlim_max = 65535;
int retval = setrlimit (RLIMIT_NOFILE, rl);
 
This runs OK when executing the program outside of valgrind but when run
within, it fails and errno is set to EPERM. The process is being run as
root on RHEL5
 
Anyone know a way around this? 
 
Thx,
Scott

[Valgrind-users] Possible Error: C​allgrind Version 3.6.1 cg_annotat​​e : Line 1 Missing command line

2011-05-24 Thread Frank Chang 
 Good afternoon, We are running callgrind and
cg_annotate version 3.6.1
on Centos Linux Version 5.5 x86_32. One month ago  Mr. Josef Weidenorfer
issued a special patch that fixed callgrind on Centos Linux Version
5.5 x86_32. We can now profile complex C++ programs which use our own
shared library libmdMatchup.so.
However, when we use version 3.6.1 cg_annotate
callgrind.out.22533 --auto = yes
-I/home/frankc/DQTTest6/MatchUpLib/Source, we obtain the error.  Line
1 Missing command line. callgrind.out.22533 was
created using the command line:
/home/frankc/DQTTest2/valgrind-3.6.1/coregrind/valgrind
--tool=callgrind --dump-instr=yes --simulate-cache=yes
--collect-jumps=yes ./MatchUpAccurate.exe. MatchUpAccurate.exe uses a
special shared library libmdMatchup.so
 Could some engineer or programmer please tell us what we are
doing wrong in using
callgrind and cg_annotate? Please let us know ifother
programmers/developers have been able to use cg_annotate version 3.6.1
on Centos Linux Version 5.5 x86_32. I am including the top 50 lines of
Callgrind.out.22533 below in case you have time to look at our
problem.
Thank you.
