Hi all,
I’ve observed that the list of colors is empty if one compiles a program with root libraries with the standard c++ compiler. That is a piece of code I used to see this:
[code]#include
#include <root/TROOT.h>
int main( void )
{
std::cout << gROOT->GetListOfColors()->At( 100 ) << std::endl;
return 0;
}[/code]
The output of the program is a zero, but I would expect to receive a not null pointer that I can cast to a pointer to TColor.
The command line I’ve used to compile the code is the following:
g++ -o test test.cc -L $ROOTSYS/lib -lCore -lCint -lHist -lMatrix -lGraf -lGraf3d -lGpad -lm -ldl
I’ve read it’s the way to read a color from the list of colors, but probably I have to tell the program to fill this list first. What is the command I’m missing?
Thanks in advance.
- Jordi.
