: If you intend to contribute to the Lazarus project itself, you need the source code from the main branch.
Open a terminal/command prompt in the extracted folder and run: make clean all :
Lazarus is the IDE, but it requires the Free Pascal Compiler to actually build programs.
: If this sounds too complex, it is much easier to download the pre-compiled installer from the Official Lazarus SourceForge .
Once the build completes, look for the lazarus.exe (Windows) or lazarus (Linux/macOS) executable in the root folder. Why use "main.zip" instead of an installer?
: Running from a zip allows you to have multiple versions of Lazarus on the same machine without them interfering with each other.
: Do not extract it to C:\Program Files on Windows, as restricted permissions can break the build process. Use a path like C:\Lazarus\ or your home directory instead. Install Free Pascal Compiler (FPC) :
Ensure FPC is installed and added to your system's PATH variable so Lazarus can find it. :
