Hi,
I just stumbled over the fact that my code, which doesn’t have an int main() function linked successfully to an executable. This feature disappeared when removing -lHistFactory from the link options, and closer inspection reveals that there is a main function defined in libHistFactory.so
nm -C /afs/cern.ch/sw/lcg/app/releases/ROOT/6.06.08/x86_64-slc6-gcc49-opt/root/lib/libHistFactory.so | \grep main
00000000000e9720 T main
After superficial grep’ping around, I suspect this is coming from https://github.com/root-mirror/root/blob/master/roofit/histfactory/src/hist2workspace.cxx#L64
means, that my falsely successfully linked executable is just another incarnation of hist2workspace.
Would it make sense to exclude hist2workspace.cxx from the creation of the shared libraries?
Thanks,
Paul
