Windows-related macro DLL_API remains unresolved in the file mentioned leading to the following error:

Comment 1 Gabriele Cosmo 2012-01-24 15:20:49 CET

The DLL_API macro is correctly set to be empty for systems other than Windows.
To note that the -internal- CLHEP module in release 9.5 is -exclusive-, it means that it should be used only if the build of the Geant4 libraries have been instructed to do so -in place- of the external CLHEP library, and the final application is built coherently with it.
It appears that your application (through ROOT/cint ?!) is wrongly picking up headers from the internal CLHEP module and mixing them with an external CLHEP installation on your system (/home/hep/shitov/local/arch64/clhep/pro/include).
