Cannot make Graph. Example broken?

[zrthstr]

When trying to make a graph as described in https://github.com/TheOpteProject/LGL#making-internet-graphs i get some errors and no output png.

Should the steps in the README.md still work if followed correctly? Or are they out of date? If they should work, on what OS/Linux distro can this be reproduced?

In my case no *.coords file gets generated.

Here is what i am doing, following the steps under: "Making Internet graphs / The same thing but step by step (if above fails):"

As far as i can debug it, the error happens on when bootstrap.sh calls run.sh calls lgl.pl in line 203 calls lglayout2D. What happens is that lgl.pl calls die()'s in line 204 but run.sh continues.

The command line arguments to lglayout2D that lgl.pl generates looks good from what i can tell. The perl script calling lglayout2D eats part of the error message so i isolated it.

LGL/testrun/internet_2000%>  /home/user/graphic/internet_graphics/LGL/bin/lglayout2D -o /home/user/graphic/internet_graphics/LGL/testrun/internet_2000/tmp/1638035734/0.coords -y -O -t 6 -E 1x1 -e -l -L /home/user/graphic/internet_graphics/LGL/testrun/internet_2000/tmp/1638035734/0.lgl

Reading in Graph from readLGL: Open of 

(the error msg stops after 'Open of' without a newline.

After the call to lglayout2D the 0.coords file is not generated. This of course then causes the image generation to fail later on.

Any idea what is going wrong here? How can i debug this further?

Happy about any pointers on how to continue.

( i'm using an up to date arch linux, but also in an debian 10, have all dependencies installed, i did the make && make install etc etc)

Drilling further down, it would appear that the error originates in include/graph.hpp line 768 called by lglayout.C in line 128. Failing to debug this further, as i don't speak c++, one thing i don't understand is where argv[optind] comes from..

Hi, I meet the same problem, how did you handle it? Could you help me, please?

[zrthstr]

Unfortunately i could never get it to work.
