ARM support on Linux?

[Vovkiv]

So, recently i become happy Raspberry Pi 4 user (with ARM Fedora Workstation). I Started preparing my usual lua/love2d environment there. And i forgot about fact that raspberry pi is arm based, while Zerobrane provide only x86_64 builds. So, i installed .sh archive and obviously failed to run zerobrane. My question is: is there will be arm support and if it possible to build for arm?

Yes, it should be possible, but you'd have to build it yourself (using the included build script). See #745 for details and related arm-build discussion.

Oh, thanks!

Welp, i tried to build it, but i can't?

#!/bin/bash
sudo dnf install -y gcc-c++ git cmake gtk3-devel wget sqlite mesa-libGL-devel lua
git clone https://github.com/pkulchenko/ZeroBraneStudio.git ~/ZerobraneSource/
cd ~/ZerobraneSource/build/
./build-linux.sh lua wxwidgets wxlua luasocket

but it fails on building wxlua:

cmake ./

I'm not really big expert in cmake, building from source and in bash in general, so i might doing something wrong. lua, wxwidgets, luasocket, builds without errors. I tried to build it on Raspberry Pi 4 itself, with Fedora Workstation 37, with everything updated.

It looks like gl library is not found for some reason; I suspect it may be because some of its dependencies are missing, wxwidgets didn't build it.

you can try removing gl from the following two lines in build-linux.sh to see if this helps (as gl library is not strictly needed for the IDE):

You'd only need to rerun the wxlua build: ./build-linux.sh wxlua luasocket

[Vovkiv]

Yep, it builds now
