Hi,
I would like to migrate from v5-34-15 (compiled with g++) to v6 beta 2 (compiled with g++) but I can’t for the moment because of the enormous number of valgrind warnings related with llvm/clang/cling
//test.cc
#include "TFile.h"
int main(int argc,char *argv[]) {
TFile file("test.root","UPDATE") ;
file.Write() ;
file.Close() ;
return 0 ;
}compiled with :
gcc -o test `root-config --cflags --libs` test.ccvalgrind test 2> valgrind.out.txtI have put the complete valgrind.out.txt in attachment :
