VTERM Color has no member named indexed

[dilzeem]

Tried to compile the vterm module, and I get the following error.

Is there something that I need to set up with regards to the VTermColor?

It looks like your version of livterm is too old. Can you try compiling with USE_SYSTEM_LIBVTERM=no? You can do this by setting vterm-module-cmake-args to -DUSE_SYSTEM_LIBVTERM=no.

[dilzeem]

Yes that worked.

I read the readme and it seems to say to -DUSE_SYSTEM_LIBVTERM=Off instead. I tried that, and it didn't work.

I also had to remove the package from elpa directory. Then it worked after that.

Thanks for the help!

Beautiful! Worked like a charm. Thanks!

I am facing this issue. Can someone expand on this? How and where should I make these changes?
I tried searching for vterm-module-cmake-args variable in emacs but could not find it. Thanks!

[Sbozzolo]

Reinstall everything from scratch removing all the old files, and it should work.

@Sbozzolo
I re-installed emacs-libvterm but getting the same error.

• removed emacs-libvterm from where I installed it, and re-installed.
• removed vterm from build folder inside straight folder.
  what other old files should I remove?
  or if there are any alternate options?
  Thanks!

Your versions of libvterm and vterm-module.so do not match. If you have the latest version of vterm, you can uninstall your system libvterm, and vterm should automatically fetch a good version of the library for you.
