I have some code that works with Fermilab D0 root version 4.x and I am trying to run it on my laptop (which is gentoo and has root 5.12/00e installed). The first problem I encountered were some problems with forward declerations of TVectorD and TMatrixD which I fixed bu including the TMaxrixDfwd.h and the Vector brother. All the libraries recompiled fine and now when I try to run the execute script I get the following error…
prophecy@prophecylaptop ~/Desktop/SVTCert $ root -b ./test.C

root [1]The code that I am running (test.C) is the following…
{
#pragma link C++ class vector<int>;
#include "TROOT.h"
gROOT->ProcessLine(".L System8Solver_C.so");
gROOT->ProcessLine(".L system8solve_C.so");
gROOT->ProcessLine(".L d0root_find_file_cpp.so");
gROOT->ProcessLine(".L NN_TRF_cpp.so");
// gROOT->ProcessLine(".L JLIP_TRF_cpp.so");

std::vector<float> cuts;
cuts.push_back(0.5);
}Now the #pragma line came from root topic

The error only crops up when I include the NN_TRF_cpp.so library (which I have recompiled with this version of root). I am just not sure where the problem is. I have checked to see if the gentoo ebuild that I was using did the “make cintdlls” which it did do. Can anybody give me a tip on what trouble shooting step I should do next? Thanks in advance. The ability to run this code on my laptop will greatly enhance my productivity (I think |-) ).

BTW: I did try to downgrade to v4 of ROOT on my laptop but the compile failed for some reason.
