|
|
+Building
|
|
|
+========
|
|
|
+
|
|
|
+1. Install the Free Pascal compiler (fpc), 3.0.4 or better, 32 or 64bit.
|
|
|
+Either from their website
|
|
|
+https://www.freepascal.org/download.html
|
|
|
+Or via Lazarus
|
|
|
+http://wiki.freepascal.org/Getting_Lazarus
|
|
|
+Or on MacOS via homebrew
|
|
|
+Or on Linux via your package manager.
|
|
|
+
|
|
|
+2. building pas2js
|
|
|
+
|
|
|
+2.1 Under Linux/macOS type
|
|
|
+make all
|
|
|
+
|
|
|
+This creates with a 64-bit fpc the executable "bin/x86_64-linux/pas2js"
|
|
|
+and a basic config file "bin/x86_64-linux/pas2js.cfg".
|
|
|
+
|
|
|
+
|
|
|
+2.2 Under Windows type
|
|
|
+
|
|
|
+Make sure that you use the make.exe from fpc, not from Delphi by setting
|
|
|
+the "PATH":
|
|
|
+For example if you installed the 32-bit version of fpc in C:\YourPathOfFPC\3.0.4
|
|
|
+
|
|
|
+set PATH=C:\YourPathOfFPC\3.0.4\bin\i386-win32;%PATH%
|
|
|
+
|
|
|
+If you installed the 64-bit version of fpc in C:\YourPathOfFPC\3.0.4 use
|
|
|
+
|
|
|
+set PATH=C:\YourPathOfFPC\3.0.4\bin\x86-64-win64;%PATH%
|
|
|
+
|
|
|
+Then compile
|
|
|
+make all
|
|
|
+
|
|
|
+If you see "Error makefile ... Command syntax error" your "set PATH" was
|
|
|
+not correct.
|
|
|
+
|
|
|
+When "make all" finished it created with a 32-bit fpc the executable
|
|
|
+"bin/i386-win32/pas2js.exe" and a basic config file "bin/i386-win32/pas2js.cfg".

|
|
|
+Configuration
|
|
|
+=============
|
|
|
+
|
|
|
+pas2js requires unit search paths (-Fu) in order to find its rtl units and
|
|
|
+rtl.js. Building and installing should have created a default pas2js.cfg
|
|
|
+containing those parameters.
