Yesterday I downloaded the new root version from cvs and compiled it on
both my new Intel MacBook Pro and on my old Titanium G4 PowerBook.
Then I compiled my library from identical source code also on both Macs,
and compilation was ok on both Macs.
To load my library I have a macro with following function:
While I was able to load my library on the new MacBook Pro, trying to load
the library on my old PowerBook caused root to crash with the stack trace
shown below.
Does someone know what the error means and why it did not appear with
the old root version 5.15/01?
Thank you in advance
Best regards

Whenever I download a new root version I run the tutorials first, including
motorcycle.C and guitest.C. “.x guitest.C+” also works.
I can start the root browser with “TBrowser b” and “new TBrowser”.
For your info I am attaching my Makefile, which is also identical for all three
platforms, since meanwhile I have tested it also on a HP laptop with FC4.
Thank you for your help
Best regards

Meanwhile I have upgraded my PowerBook from OS X 10.4.4. to 10.4.9. I have also updated XCode
from 2.1 to 2.4.1. In addition I have downloaded once again a new root version from cvs.
Sorrowly, the error remains the same. Putting xps.so in $ROOTSYS/lib also causes the same error.
I have also tested my library on the MacBook Pro and a laptop with FC4:
On all three systems I get the same error:
“Error in TPluginHandler::SetupCallEnv: class TRootGuiFactory not found in plugin Gui”
In contrast, when using the old root version 5.15/01 everything is ok.
Interestingly, when I “build” my R package, which compiles the library source code automatically,
and load my package into R, then my library works as expected on my Intel-Mac but not on my
PowerBook, using either the old or the new root version. However, when I try to load this library
into root, then I get this error!
Since my “Makefile” includes “Makefile.arch” from root/test, I decided to compile the root/test
examples. While I can load these libraries when using the old root version, with the new root
version I get the error:
"Load Error: Failed to load Dynamic link library /Volumes/CoreData/ROOT/root/test/./Hello.so"
See my new topic: “Error loading root/test libraries!”
Could there be a problem with “Makefile.arch”?
It is very important for me to use “Makefile.arch” to allow architecture independent compilation.
Usually, R packages containing C source code use the built-in R configuration for architecture
independent compilation. This is not possible for me since my source code depends on root.
does your xps.so lib depend on specific ROOT libraries? What happens if you explicitly load libGui before loading xps.so? Once all dependencies are know create a xps.rootmap file to automatically load these dependencies.
Thank you very much, loading libGui first finally solved my problem on all three computers.
Interestingly, when my package and library is called from within R, everything works fine, so I assume:
Is it correct, that loading libGui first is only necessary for CINT, but not when my library is called from another program?
You propose that I create a xps.rootmap file using rlibmap. When looking at: root.cern.ch/phpBB2/viewtopic.php?t=4778
I have the feeling that it is easier for a user to simply load libGui.
E.g. my library contains 140 classes, so I would need to call “./do_map ClassXX mylib > mylib.rootmap” 140 times.
Thank you for this very good idea.
Sorrowly, the error remains the same. I tried to put RootGuiInit in the .h file, the .cxx file, with/without ClassDef, nothing worked.
However, the most important issue is, that with loading libGui now everything is ok.
