Inochi2D and Inochi Creator are still in a phase of rapid development, doing dub add replaces the dependencies on the main branch with older versions on the dub database. clone the inochi2d repository and the bindbc-imgui repositories and use dub add-local to add them as local packages at version 1.0.0

You'll need to compile cimgui from source (which you can find in the bindbc-imgui source tree, you just need to recursively update its sub modules)

[playmer]

Expanding a tiny bit more, if you have issues building that cimgui in the bindbc repo on Linux, please raise the issue in the bindbc repo, as it's our fault, not cimguis. I need to write better docs about this whole process and I don't have a primary Linux machine atm.

[sanket143]

thanks, I got it to compile successfully but it failed with a segmentation fault. It seems it's the same issue as discussed in #1

[LunaTheFoxgirl]

Have you compiled cimgui from source and make installed it?
Additionally you'll need SDL2 installed.

In later releases I plan to distribute Linux versions as AppImages with this stuff pre-compiled.

[sanket143]

Yes, I did along with SDL.

In later releases I plan to distribute Linux versions as AppImages with this stuff pre-compiled.

that'll be great, but it still would've been helpful to be able to easily make it work by compiling from source, for contributors. Though it is possible to compile, I haven't been able to run.

[sanket143]

Since I got segmentation fault, I ran it through gdb and got this

I am not much familiar with dlang and .so files, can I say that the issue was in building the cimgui.so?

[LunaTheFoxgirl]

Potentially, it's at least not finding the SDL2 symbols in the imgui .so file, it seems.
