WebAssembly/Compiler

Instructions

Compiling the compiler

Get the sources:

 git clone https://github.com/skalogryz/freepascal fpc-wasm

switch to correct branch:

 cd fpc-wasm
 git checkout webasm

compile:

 cd compiler
 

Using lazarus:

 open ppcwasm.lpi

hit the "compile" button.

On the command-line:

 fpc -dnoopt -dwasm -Fiwasm -Fuwasm -Fusystems -S2 pp.pas 

the compiler can be renamed

 mv pp ppwasm

or, on windows:

 mv pp.exe ppwasm.exe

Using the compiler

You need a system.pas unit. It can be found here:
