Re: [ROOT] ROOT 2.23.12: Accessing funct

Hi Masaharu,

I had already tried the two namespace pragmas that you suggested (I
hinted at this in my original e-mail), and they don't work either.  So,
the problem/question remains - how do I import a function in a namespace
even though I am already using the two pragmas that you recommend?  I
have attached the two files that are necessary to run the following
command, which demonstrates the problem:

  $ rootcint -f cross_sectionDict.cxx -c cross_section.hxx LinkDef.h

Were you actually able to verify that you can run the above command
without problems?  It definitely does not work with ROOT 2.23.12 (which
corresponds to CINT 5.14.25).

Thank you for your help and expertise.
