Hmm, have you run `git submodule init`? (You'll also need the module you actually want to run as a separate step.) Feel free to stop by our Discord if it gives you any more trouble. 😕

Maybe you could understand if I've missed something if I describe precisly what I've done

In details

First I've installed the requested lib
sudo apt install -y build-essential ccache git libboost-dev libboost-filesystem-dev libboost-iostreams-dev libboost-regex-dev libboost-locale-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev libglew-dev libpng-dev libcairo2-dev libfreetype6-dev libvorbis-dev

Then download the code
git clone https://github.com/anura-engine/anura.git

locate the folder
cd anura

run the command you've suggested
git submodule init

And finally
make -j$(nproc)

Unfortunatly it don't fixe the building error

"Aucun fichier" mean "no such file"

[DDR0]

Thank you for the good error log, that is a very useful reply. I don't know why it's not working, as that *looks* like the correct steps. I'll see if I can reproduce here over the next day or two, and hopefully have a better answer for you soon.

Hey, sorry for the delay here.

Try running git submodule update after git submodule init and let me know if that works. It seems init just sets things up, it doesn't actually get the files we need.

[DDR0]

I'm going to close this bug as I have heard no further action on it for a while now. Please reopen it if the issue persists.

[DDR0]

Some minor diagnosis and updates on this issue:

To verify the submodule has cloned correctly, you should see these files running ls in the imgui folder in the base Anura folder:

0 in ~/Projects/Anura/imgui git:(2379a8b3)  
$ ls
docs        imgui.d         imgui_draw.o      imgui_user.inl     imstb_rectpack.h  misc
examples    imgui_demo.cpp  imgui.h           imgui_widgets.cpp  imstb_textedit.h  spline.h
imconfig.h  imgui_draw.cpp  imgui_internal.h  imgui_widgets.d    imstb_truetype.h
imgui.cpp   imgui_draw.d    imgui.o           imgui_widgets.o    LICENSE.txt

There's ongoing work fixing this entirely in the unvendor-imgui branch.

This issue has been hard-reproduced by Knightron#0666 in the #tech-support channel. It appears that, on some setups, Git submodules just don't work?
