RE: [ROOT] How to use third party's shared library in Root/Cint

Hi,

As suggested by the error message you can also use the -p options when 
running rootcint:

rootcint dict.C -c -p engine.h

However, on Solaris you may need to modify the file $ROOTSYS/MAKEINFO
to replace the lines:

CPPPREP     = CC -C -E

by

CPPPREP     = /usr/ccs/lib/cpp -E -C -B -D__sun -D__sparc -D__unix

Philippe.
