Description
The following macro:
void draw_file() {
|
using namespace ROOT;
|
auto canvas = Experimental::TCanvas::Create("Canvas Title");
|
canvas->SaveAs("th1.png");
|
}
|
gives:
Processing draw_file.cxx...
|

You are probably missing the definition of ROOT::Experimental::TCanvas::SaveAs(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, bool, std::__1::function<void (bool)>)
|
Maybe you need to load the corresponding shared library?

if instead of SaveAs we do canvas->Show(); then the symbol (Show) is found. Show is defined at the same level of SaveAs. Adding R__LOAD_LIBRARY(libROOTGpadv7); in the macro fixes the issue. but this extra library load is not needed for Show.
