Hi,
I am trying to run a class which was originally produced by MakeSelector()
in a standalone program. The program looks like this:
#include "selector.h"
int main(int argc, char **argv) {
selector *sel = new selector();
}
The selector.C and .h file are like they have been produced by
MakeSelector() without any changes.
When I am trying to compile with:
gcc `root-config --cflags --libs` program.C
it produces the following error:
/tmp/ccThcUXm.o(.gnu.linkonce.t._ZN8selectorC1EP5TTree+0x19): In function
`selector::selector[in-charge](TTree*)':
: undefined reference to `vtable for selector'
collect2: ld returned 1 exit status
Does anyone know what this message means? I am using RooT 3.10-01 on RH9.
Thanks, Frank
