Compiling the code on ubuntu 20.04 LTS with

$> g++ -Wall -g main.cpp -o build/main

Gives the following error:

In file included from main.cpp:15:
topol.h: In function ‘std::string toString(T)’:
topol.h:507:12: error: could not convert ‘result’ from ‘std::ostream’ {aka ‘std::basic_ostream<char>’} to ‘std::string’ {aka ‘std::__cxx11::basic_string<char>’}
  507 |     return result;

Currently, the diagrams are generated with two labels at each circle in the Venn diagram. These labels correspond to the number of elements withing each circle and to the number of the circles these elements belong two.

In some cases it might be interesting to have also all the names of all the element within each group. It would also be very useful if the names of the elements within each group are extracted automatically by the perl script that generates the ascii input file the the program generating the diagrams.

So, this issue is a suggestion for improvement.

I want to make a venn diagram for 15 sets.
I have followed the instructions that vqf, the creator of the package, has kindly indicated to me through this stackoverflow query. Unfortunately, nVennOGL.exe is not working for me.
I have created the file venn.txt, according to the format indicated in the README of the package repo, but when I run the nVennOGL.exe, nothing happens (neither a window opens, nor a new file is created). The files are in the same folder
venn.txt

Hi, Does this tool support creating diagrams for more than 6 sets? I notice that the web interface only supports 6 so I tried to use the command line tool, but the program hit a segmentation fault whenever I fed the program more than 6 sets. Is there a way to run the command line tool to generate diagrams for more than 6?

Thanks!
