Error while compiling

ROOT

Hello all,

I have a macro that I used to compile with
root> .L glfit.cpp++

This always worked fine, but today I wanted to compile the old macro again and I got the following error:

root [5] .L glfit.cpp++

Can anybody please tell me what is suddenly wrong? I didn’t change the macro since the last time when it still worked. I also tried to use a newer version of Root (5.10.00e) but without succes.

Many thanks in advance for any help!

Cheers,
Gerolf

Hi,

this is strange - ACLiC fails building the library, but it doesn’t report any errors (the “main” error comes from the “let’s find out what’s wrong” stage - you can ignore it). Is the library successfully built, and ACLiC just confused? Or did you run out of AFS space? Is the file / dir writable? Try to copy a file about the same size as the lib you’re trying to build to /afs/cern.ch/user/s/schlager/TB-Analysis/muons_tile/glfit_cpp.so to make sure…

If all that fails, set gDebug=7 on a root prompt before doing “.L glfit.cpp++”, and try to execute the command that ACLiC will now prompt one by one on a shell, to check which one fails. Maybe that gives a hint; otherwise please post the result of these checks, so we can have another look.

Axel.

Hello,

I think I found the problem: The library was already loaded by Root when I tried to compile it. I think this produced the error!

And you were right - the library was successfully built although there was the error message.

Thanks a lot for your help Axel!
