lost?!

ok.

now we know that
ACLiC works in some cases
libTreePlayer is loadable
if ACLiC tries to link with libTreePlayer, it does not work.

What is the command line used by ACLiC to compiler in the case where testing.cxx (whatToHell.cpp) contains a reference to TTreeFormula.

Philippe.

But one line up

I still do not know why it does not work (but it might have to do with the way the compiler is handling the template instantiation :frowning: … without access to the machine I would not be able to investigate further) but I think the following would make the problem disappear:TString cmd = gSystem->GetMakeSharedLib(); cmd.ReplaceAll("$LinkedLibs",""); gSystem->SetMakeSharedLib(cmd);(to be issued once per session before the first ACLiC command.

Thank you, Philippe,

it does the job but I still do not understand all of it.
