When linking TMVA to a ROOT installation with non-standard LDFLAGS, p.e. doing a 32bit build on 64bit MacOS X, the build fails as TMVA does not obey the LDFLAGS which were used to build ROOT. I have attached a diff for the Makefile which fixes this problem.
Diff for TMVA Makefile
Hi,
You are right, the Makefile should be modified according to your suggestion. I added a section to the tutorial tto describe what to do if this occurs (section local installation on MAC, see https://twiki.cern.ch/twiki/bin/view/TMVA/WebHome\) and the fix will also be included in the next patch/version.
