Re: use of '#define FOO' in macro

Hello ROOTers,

I found an old post in roottalk.
http://root.cern.ch/root/roottalk/roottalk98/2493.html I tried this but I still get 'Error: Symbol SHORT_IMG is ...'.

I added
#defined SHORT_IMG 16
in FITSfunction.h, and
#pragma link C++ global SHORT_IMG;
in FITSLinkDef.h .

These two headers correspond to CERNfunction.h and CERNLinkDef.h (see http://root.cern.ch/root/HowtoCERNLIB.html)

Sincerely
