I have a solution which contains a number of subprojects. The “main” one is a Cooper/Silver JavaFX test application. Since it has a reference to jfxrt (in a specific folder on my Mac’s drive), bringing the project over to my Windows VM forces me to remove the invalid reference to jfxrt and add a new one pointing to the proper location on the Windows drive. Is there a better way to manage this?
Also, my macOS shared library project (dylib) is used for JNI and, as a standard, needs to have the jnilib extension instead of dylib. I don’t think there’s any place in the project settings that would cover this (and this would have to be platform-specific, again)

Indeed there is. Add a new .xml file in `/Users/mh/Library/Application Support/RemObjects Software/Elements/Reference Paths/Cooper` and configure in it the path where you want Fire to locate your Java references. Do the same in `%APPDATA%\RemObjects Software\Elements\Reference Paths\Cooper` on Windows.

Hmm. Currently we dont have an option to influence the file extension of the output — I wasn’t aware that’s a valid thing, to have those not be .dylib. I’ll add an option for vNext. I assume this is only needed for macOS dynamic, libraries, not for Island/Windows/Linux?
**Update** : Done, setting is called `BinaryExtension`.

Great. I’ll take a look at this.

This is more of a cosmetic/nice to have setting. I’m sure there are some instances where this could be useful on other platforms. Thanks for adding it!

Make sure to check out [Reference Search Path XMLs](https://docs.elementscompiler.com/Projects/References/ReferencesXMLPaths/), as well as the other topics under “References”, as well.

As the jfxrt.jar file is always in lib/ext (under the JRE folder that Fire/Water already know about), shouldn’t there be a way to specify it in the .elements project file directly (say, using something like $(JRERoot)/lib/ext/jfxrt.jar) ?

Hmm, if its in JRE/lib, kit should be found… I’ll check if maybe I need to add recursion there…
But wait, but is this the Toffee/macOS JNI project we’re talking about, or the Java “host” project?

Fixed, vNext will check recursively in all JRE/lib subfolders for references.

It was the Java host project. Adding recursion should address the issue. I assume this means the reference entry will no longer need the hint location.

Correct. the refs will work w/o HintPath (if one is present and valid, it’ll still be used, if its present but invalid it will be ignored). Add References in Fire and Water will also show them,

I can confirm this works properly in 2271

I haven’t found the BinaryExtension option in my macOS shared library project. Is this something that can only be edited within the .elements file?
Anyhow, it worked when I added the option to the project file with a text editor.

Correct, this is not (and probably will not be) an officially supported/exposed option, you need to manually add it to the project.
