ok, lemme try it  

From you latest error, the ai said you need to install Premake 5 binary

Maybe try updating or reinstalling cmake   Another thing the ai said:  Common Causes for "No Such File" Wrong Root: You are inside ~/Documents/Projects_Collab/Farming++ which appears to be a different project. Ensure you cd into the actual 0 A.D. source folder first.  Incomplete Download: If you downloaded a tarball, ensure you extracted both the unix-build and unix-data archives. If using Git/SVN, ensure the checkout finished successfully. Script Permissions: If the file exists but fails to run, make it executable: chmod +x build/workspaces/update-workspaces.sh

yeah sorry for that, i forgot to change the directory. lemme redo it and see if it actually works ~/Documents/Projects_Collab/0ad main ?3 > pwd      /home/Manas/Documents/Projects_Collab/0ad ~/Documents/Projects_Collab/0ad main ?3 > cd build/workspaces ./update-workspaces.sh cd gcc make -j$(nproc) ./update-workspaces.sh: line 46: ../../libraries/source/premake-core/bin/premake5: No such file or directory ERROR: Premake failed cd: no such file or directory: gcc make: *** No targets specified and no makefile found.  Stop. this is still the same case

So I am not super framilar with cmake either. But are you running the command from the root directory? I just asked ai, and have you check this? You must run these commands from the root of the 0 A.D. source folder (where the build/ directory is located), not from inside build/workspaces or an unrelated project folder like Farming++.  Check your current location and contents: pwd ls -R build/workspaces You should see update-workspaces.sh and a gcc/ folder inside build/workspaces. If build/workspaces is empty or missing, your source download is incomplete.
