Problem loading Garfield libraries in MacOs

Garfield++
1

I am running into problems while trying to load Garfield libraries into ROOT.

Just after the Garfield compilation succeeds, I load the Garfield setup.sh and try using gSystem->Load("libGarfield.dylib").

I get the following error:

I would expect that setupGarfield.sh would load all the necessary paths.

It seems it tries to find libmagboltz.11.dylib. The file is found inside /Users/jgalan/apps/garfield6/lib, same place as libGarfield.dylib. So why it does not find it? Perhaps in MacOs magboltz needs to be added to the compilation targets somewhere.

Any help welcome!
Thanks!

Hi @Javier_Galan,

It seems it’s trying to locate the library using only the @rpath (run path) of the binary -in this case the ROOT binary-.
Perhaps you could try manually adding the directory you mention as part of the library search path list, as in

$ export DYLD_LIBRARY_PATH=/Users/jgalan/apps/garfield6/lib:$DYLD_LIBRARY_PATH
$ root
root [0] gSystem->Load("libGarfield.dylib"); // or alternatively, write
                                             // the full path here
...

For this, maybe @hschindl knows better.

Cheers,
J.

I get a different error now. Perhaps is not properly finding the pcm file?

To me it seems like some path is missing in the include path list, but @hschindl perhaps knows or has seen this before.

Out of curiosity, did you source the setupGarfield.sh file in your current shell?

5

Can you try loading libmagboltz before libGarfield?

gSystem->Load("libmagboltz.dylib");
gSystem->Load("libGarfield.dylib");
6

Perhaps the dictionaries haven’t been generated, or they were not included inside the target?

Hm, strange… it works on my MacBook (macOS 12.6, ROOT 6.26/02). What OS and ROOT version are you using?
