ExRootAnalysis Installation Error --invalid

[CHEN NING]

My problem is the following:

I have already installed MG5 and ROOT successfully on my machine. I ran 'install ExRootAnalysis' under the MG5. The downloading is successful, while something wrong happens to the compiling. It returns the following information:

compile ExRootAnalysis. This might takes a while.
>> Generating tmp/src/ExRootAnalysisDict.cc
rootcint: error while loading shared libraries: libCint.so: cannot open shared object file: No such file or directory
make: *** [tmp/src/ExRootAnalysisDict.cc] 错误 127
Error detected during the compilation. Please check the compilation error and run make manually.

Apparently something wrong under the directory /ExRootAnalysis/tmp. Actually there was simply nothing there. Then I copied everything under this directory from my friend, who installed ExRootAnalysis successfully. After this, I returned to the /ExRootAnalysis, did the 'make', and it returned with:

>> Building lib/libExRootAnalysis.so
>> Building Example
>> Building ExRootHEPEVTConverter
>> Building ExRootLHCOlympicsConverter
>> Building ExRootLHEFConverter
>> Building ExRootMain
>> Building ExRootSTDHEPConverter

May I know what's wrong with my ExRootAnalysis? Thanks a lot.

Hi Chen,

I think you succeed to fix this problem (If i refer to your comment on https://bugs.launchpad.net/bugs/1014002)
Looks like Matthew has the same trouble as you, could you indicate how you solve your problem?

Cheers,

Olivier

Just in case, I think that the solution should be:
1) run the command
locate libCint.so
(or but much longer and less efficient)
 find / |grep libCint.so
in my case, the first one diden't return anything but the second returns:

./Documents/prog/root/lib/libCint.so

Then I add in .bashrc the following lines:
export ROOTSYS=/Users/omatt/Documents/prog/root/
export DYLD_LIBRARY_PATH=$ROOTSYS/lib:$DYLD_LIBRARY_PATH

Cheers,

Olivier

Since this resolve the problem for Matthew, I will consider this bug as fixed.
(Will put a status invalid since this is a configuration problem and not linked to a bug in ExRootAnalysis/MG5)

Cheers,

Olivier

PS: Chen if you still have problem with this at a point, don't hesistate to tell us here, I'll then re-open the bug.
