crash when using std::vector

Dear Root experts,

        I have a macro using an std::vector<TFile*>. When I run it in root I get a crash due to the std::vector: I get the crash when I try to get a histo from a file:

     TH1D* hReducedEff = (TH1D*)fVector[i]->Get("McSelection/ HltPathsReducedEff");

If I try to compile the macro, I get an error in compilation:

/usr/bin/ld: skipping incompatible /usr/lib64/libm.so when searching

/usr/bin/ld: skipping incompatible /usr/lib64/libm.a when searching

Load Error: Failed to load Dynamic link library /home/chiorbo/scratch0/ CheckTriggerTableForSusy_1e31_226_HLT/src/HLTriggerOffline/SUSYBSM/ rootmacro/./makePlots_C.so

How can I solve that?

Thanks,
