[fpc-devel] Planning to experiment with FPC extentions

[Ryan Joseph]

I started by using lazbuild with one of the .lpi files included in the fpc sources (add debug information when building also). 

lazbuild /fpc/compiler/ppcx64.lpi

Next thing to do is put a syntax error in a example program and build it using the compiler (/fpc/compiler/ppcx64 myprog.pas for example) and a debugger (I use VSCode on macOS now but Lazarus works). Step through the compiler line by line until you understand the basics of where you are. Eventually add more syntaxes to your example program and step around in the debugger to analyze how it works.

That's basically all the information there is sadly. I thought of making a little screencast video of myself doing this but I'm not sure how useful that would be.
