guidelines for installing on Linux

Hello! I'm attempting to install 42 from the zip file, 42 20230210.zip downloaded from sourceforge, but have been encountering a non-zero return code while running make 42 && make install for an Ubuntu 22.04 virtual environment. Any ideas as to what could be the problem?

I don't know what "make install" does, which means that you don't need it. Try just "make" or "make 42" from the directory where the makefile is. You should get a command-line executable in the same directory.

Removed make install as of ODU-CGA-CubeSat/sealion-workspace-image@a37d344 but still encountering a non-zero return code error https://github.com/ODU-CGA-CubeSat/sealion-workspace-image/actions/runs/4875324210/jobs/8697375704#step:5:738

Hmm. Your environment is more sophisticated than I am, so I don't know how much help I can be. But if make is generating errors, it might be helpful to see what those errors are. Does /tmp/42_build_output.txt have anything informative in it?

I just installed and ran 42 on Windows WSL using Ubuntu 22.04 without any issues. The 5/4/23 logs in this issue have expired so I can't view them. I've had this environment setup for C development prior to trying the 42 installation so I can't step you through a clean install. This is the environment I think you need:

sudo apt update
sudo apt install build-essential g++
sudo apt-get install freeglut3-dev
You may need these if they're not included with the freeglut3-dev package:
sudo apt install libgl-dev libglfw3-dev

A build error like "#include <GL/glut.h> not found" indicates a GL installation issue. If you comment out "GUIFLAG = -D ENABLE_GUI" in the Makefile then you should be able to build and run 42 without graphics just to show that everything except the GUI is working correctly.

To run 42 enter "./42"

You should also issue a "make clean" before you re-building after an erroneous build.
