# The Optional Retro Compiler
|
|
|
|
|
|
|
|
|
|
In addition to the base system, users of RETRO on Unix hosts
|
|
|
|
|
with ELF executables can build and use the `retro-compiler`
|
|
|
|
|
to generate turnkey executables.
|
|
|
|
|
|
|
|
|
|
## Requirements
|
|
|
|
|
|
|
|
|
|
- Unix host
|
|
|
|
|
- ELF executable support
|

|
|
|
- `objcopy` in the $PATH
|

|
|
|
|
|
|
|
|
## Building
|
|
|
|
|
|
|
|
|
|
make bin/retro-compiler
|
|
|
|
|
|
|
|
|
|
## Installing
|
|
|
|
|
|
|
|
|
|
Copy `bin/retro-compiler` to somewhere in your $PATH.
|
|
|
|
|
|
|
|
|
|
## Using
|
|
|
|
|
|
|
|
|
|
`retro-compiler` takes two arguments: the source file to
|
|
|
|
|
compile and the name of the word to use as the main entry
|
|
|
|
|
point.
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
|
|
|
|
|
Given a `hello.forth`:
|
|
|
|
|
|
2020-01-14 20:38:03 +01:00
|
|
|
~~~
|
|
|
|
|
:hello 'Hello_World! s:put nl ;
|
|
|
|
|
~~~
|
2019-03-19 19:14:28 +01:00
|
|
|
|
|
|
|
|
Use:
|
|
|
|
|
|
2020-01-14 20:38:03 +01:00
|
|
|
retro-compiler hello.forth hello
|
2019-03-19 19:14:28 +01:00
|
|
|
|
|
|
|
|
The compiler will generate an `a.out` file which you can
|
|
|
|
|
then rename.
|
|
|
|
|
|
|
|
|
|
## Known Limitations
|
|
|
|
|
|
|
|
|
|
This does not provide the scripting support for command line
|
|
|
|
|
arguments that the standard `retro` interface offers.
|
|
|
|
|
|
|
|
|
|
A copy of `objcopy` needs to be in the path for compilation
|
|
|
|
|
to work.
|
|
|
|
|
|
|
|
|
|
The current working directory must be writable.
|
|
|
|
|
|
|
|
|
|
This only supports hosts using ELF executables.
|
|
|
|
|
|
|
|
|
|
The output file name is fixed to `a.out`.
