# sample-jep-graal
Basic compilation of Jep with Graal
## Prerequisites
Make sure that [graal](https://www.graalvm.org/) and [leiningen](https://leiningen.org/) are installed. Also make sure that the python installation is `v3+` If need be, the runtime python and pip commands can be set through ENV variables:
```
export JEP_PIP=pip3
export JEP_PYTHON=python3
```
[jep](https://github.com/ninia/jep) will be installed if not found.
## Building
The `prebuild.sh` command needs to be run once. It builds a jar and instruments it with `-agentlib:native-image-agent` attached.
```
$ preimage.sh
╰─$ ./prebuild.sh
BUILDING JAR
INSTRUMENTING JAR
.... ....
INSTRUMENTING COMPLETE
COPYING CONFIGS from ./log to ./native
PREIMAGE SUCCESS
```
Once the two files `jni-config.json` and `reflect-config.json` are generated, the native image can be built:
```
$ lein native-image
╰─$ lein native-image

[../jep.graal/target/jep-graal:92601] (cap): 1,569.69 ms, 0.96 GB

[../jep.graal/target/jep-graal:92601] write: 697.21 ms, 2.61 GB
[../jep.graal/target/jep-graal:92601] [total]: 70,857.87 ms, 2.61 GB
Created native image .../jep.graal/target/jep-graal
```
The binary is compiled to `target/jep-graal`.
## Running
Currently running the binary causes an error:
```
$ target/jep-graal
