Example of Installing Fiji with the IJP ImageJ Launcher on Mac OS X Arm64
-------------------------------------------------------------------------
#### 1. Download FIJI without JRE
Go to https://fiji.sc/ and select "Download the no-JRE version".
That should het you file called `fiji-nojre.zip`
#### 2. Unzip the `fiji-nojre.zip` in the directory of choice
In Mac OS X, if you double-click on the file `fiji-nojre.zip`
You should get `Fiji.app` click and select "show Content"
#### 3. Create place for Java (JRE)
Inside `Fiji.app` create directory `java`.
Next to directories that are already there, like `Contents`, `images`, `jars`, ...
#### 4. Download Java JRE or JDK,
In browser open https://adoptium.net/temurin/releases/
Select:
* operating system: `macOS`
* architecture: `aarch64` also know as Apple Silicon or Arm64
* package: `jre` (`jdk` is fine too, is larger supports Java compilation)
* version: `11` (`17` will work too, but you will not have JavaScript available, if you use it)
Click on `tar.gz` button and download to the `java` directory you created earlier.
You should have file like `OpenJDK11U-jre_x64_windows_hotspot_11.0.19_7.tar.gz`.
#### 5. Uncompress into the `java` directory
That will create directory like `jdk-11.0.19+7-jre`
#### 6. Download IJP ImageJ Launcher to Fiji.app directory
Go to [Releases] and download `???` and `???.???`
#### 7. Start ImageJ
In Fiji.app double-click on `???.???` (note the extension ???) that should start FIJI.
You can also create an alis on the desktop to avoid navigating to Fiji.app directory each time.
Press ??? and ??? and drag `???.???` to the Desktop.
It will create an alias.
Now you can double-click on the alias `???.???` on the Desktop to start Fiji.
If you have problems installing, please report in [Discussions]
Troubleshooting
---------------
1. Open command prompt (terminal).
2. Navigate to `Fiji.app` directory
3. Run IJP ImageJ Launch typing: `./ijp-imagej-launcher --debug`
You should see diagnostic information about how `ijp-imagej-launcher` is attempting to start Fiji.
The error messages shoudl help you to address the issue.
Please use [Discussions] if you have additional questions
Developer Setup
---------------
Information here is only applicable if you want to rebuild from sources.
Setup Scala Native dependencies following instructions at:https://scala-native.org/en/v0.4.12/user/setup.html
In brief, you will need the following installed: JDK, SBT, and LLVM/CLang.
Details depend on OS.
On Windows you will also need Visual Studio 2019 (the Community Editions is sufficient).
Alternatively on Windows, you can build using WSL Linux prompt, in that case, follow Linux installation instructions.
This should work with JDK 8 or newer, including the latest JDK 20.
After requirements are installed, you should be able to build and run the launcher using command:
```shell
sbt run
```
You can pass additional command line arguments, for instance `--help`:
```shell
sbt "run --help"
```
Notice the use of quotes.
