## Build instructions
|
|
|
|
|
|
|
|
|
|
#### Java compatibility note
|
|
|
|
|
|
|
|
|
|
It is recommended to use JDK 1.8 for building Millfork.
|
|
|
|
|
If you have multiple Java versions installed, enter
|
|
|
|
|
`set JAVA_HOME=PATH_TO_JAVA\bin ` (Windows)
|
|
|
|
|
`export JAVA_HOME=PATH_TO_JAVA/bin ` (Mac/Linux)
|
|
|
|
|
(where PATH_TO_JAVA is a path to one of your JDK installations)
|
|
|
|
|
into the command line before running sbt to choose a JDK.
|
|
|
|
|
|
|
|
|
|
### Building without tests
|
|
|
|
|
|
|
|
|
|
Setting up the test suite for Millfork is tricky, so if you don't need the tests, you can remove them.

|
#### Prerequisites
|
|
|
|
|
|
|
|
|
|
* JDK 1.8
|
|
|
|
|
|
|
|
|
|
* sbt
|
|
|
|
|
|
|
|
|
|
#### Steps
|
|
|
|
|
|

|
|
|
* run `sbt -DskipTests compile`
|

|
|
|
|
2020-11-02 12:47:16 +00:00
|
|
|
* run `sbt -DskipTests assembly`
|
2020-07-31 22:36:57 +00:00
|
|
|
to build the executable jar file, it should appear in `target/scala-2.12`

### Building with tests
|
|
|
|
|
|
|
|
|
|
Test suite is useful if you plan on modifying the compiler. Some test dependencies need manual installation.
|
|
|
|
|
|
|
|
|
|
#### Prerequisites
|
|
|
|
|
|
2020-09-22 15:59:32 +00:00
|
|
|
* JDK 1.8 or later
|
|
|
|
|
|
|
|
|
|
* Millfork up to version 0.3.22 used to require exactly JDK 1.8 with Nashorn,
|
|
|
|
|
as the tests didn't work on newer versions
|

### Building a native executable
|
|
|
|
|
|
|
|
|
|
This is experimental.
|
|
|
|
|
|
|
|
|
|
#### Prerequisites
|
|
|
|
|
|
|
|
|
|
* an executable jar with Millfork (see above)
|
|
|
|
|
|
|
|
|
|
* GraalVM 19 or later
|
|
|
|
|
|
|
|
|
|
* native-image
|
|
|
|
|
|
|
|
|
|
* other tools required by native-image, appropriate for your operating system and GraalVM version (for example, Windows SDK 7.1 on Windows)
|
|
|
|
|
|
|
|
|
|
* a lot of RAM
|
|
|
|
|
|
|
|
|
|
#### Steps
|
|
|
|
|
|
|

|
* navigate to the directory containing the jar, most likely `target/scala-2.12`
|
|
|
|
|
|
|
|
|
