Running a macro that uses an external class

ROOT
1

Hi,

I have these three files in my current directory:

macro.C
RooMyPdf.cxx
RooMyPdf.h

I do .x RooMyPdf.cxx+ in root and then RooMyPdf_cxx.so appears.

macro.C includes RooMyPdf.h and uses the RooMyPdf class, but when I run macro.C+, I get this error:

dlopen error: /home/anlevin/8.811/./pset7_task3_C.so: undefined symbol: _ZTV8RooMyPdf

How can I link to RooMyPdf_cxx.so when I do root macro.C+?

It does this automatically when I do root macro.C, but I want to compile the code so that it will run faster.

Try:
root -b -l -q RooMyPdf.cxx+ macro.C+

Thanks.

That solved the problem (except for the -b part, I had to take out -b since I wanted a graphic to pop up).
