library paths shouldn't be hardcoded

[aabacchus]

Factor looks for libraries named libgtkglext-x11-1.0.so (and for gdk) but on my system, the library has at least a .0 suffix, so I had to

ln -s libgtkglext-x11-1.0.so.0 /lib/libgtkglext-x11-1.0.so
ln -s libgdkglext-x11-1.0.so.0 /lib/libgdkglext-x11-1.0.so

but the correct library paths are in the generated basis/gir/*.gir files, so this step shouldn't be necessary.

Thank you -- we've been relying on the -dev packages on e.g. ubuntu etc, but you're right this is a better approach.

Hello, I face issue with this library too. Unfortunately, I can't start factor on Debian 13

./factor -i=factor.image&

╰─ Cannot resolve C library function ─╯ Library: DLL" libgtkglext-x11-1.0.so" Symbol: gtk_gl_init DlError: libgtkglext-x11-1.0.so: cannot open shared object file: No such file or directory

There is no such library any more in Debian

Does that message mean that Factor still relies on GTK2? IIRC it was EOL:ed around 2020.

I have the same issue on Debian Trixie/13.

[mrjbq7]

Currently, yes. We need to update the GTK2 backend to GTK3/4.

From the Discord:

installing the .deb from a previous Ubuntu version wasn't something I really thought would work, but I installed the plucky/25.04 version.

That almost works -- I needed to manually add some symlinks that the factor binary was looking for: in /usr/lib/x86_64-linux-gnu I did:

sudo ln -s libgtkglext-x11-1.0.so.0.0.0 libgtkglext-x11-1.0.so
sudo ln -s libgdkglext-x11-1.0.so.0.0.0 libgdkglext-x11-1.0.so

Right, thanks. I was planning on showing Factor to an intern but I'm not going to drag them through something like that, I'll pick some other niche language I've used instead.

@cess11 I have ported Factor's UI to GTK3. The latest Linux nightly build has it enabled, as does the latest git ref.
