Hi all,
I used MakeSelector to automatically generate a .C and .h file using a command like the following:
root [#] h42->MakeSelector(“myselector”)
After generating my .C and .h file, I attempted to compile the class into an executable with g++
Here is my simple code for that:
[code]#include
#include
#include
#include
#include “SMWZ.h”
using namespace std;
int main(int argc, char *argv[])
{
SMWZ();
return 0;
}[/code]
Before running that code, I changed SMWZ.h so that vector became std::vector and string became std::string
Then, I attempted to compile using the following makefile
[code]all: ZJet
ZJet: ZJet.o
g++ -O3 -ffast-math -funroll-loops -ansi root-config --libs -o ZJet ZJet.o
ZJet.o: ZJet.cpp
g++ -O3 -ffast-math -funroll-loops -ansi root-config --cflags -c -o ZJet.o ZJet.cpp[/code]
The exact error message I am getting is:
g++ -O3 -ffast-math -funroll-loops -ansi root-config --libs -o ZJet ZJet.o
ZJet.o: In function main': ZJet.cpp:(.text+0x47): undefined reference tovtable for SMWZ’
collect2: ld returned 1 exit status
make: *** [ZJet] Error 1
If this is relevant, all of this was done using ROOT 5.28 and gcc4
