[SOLVED] Building for windows/linux from macos and vicaversa

[mudlee]

UPDATE: I just found this topic: http://forum.lwjgl.org/index.php?topic=6647.0
I think this is the answer, but let's wait for a confirm.

Hi.

I refactored my app to be able to use java9 modules and I also successfully created a build pipeline with jlink, so now I have a standalone app from my game, which is good. However, I could not figure out, how can I build for windows/linux on osx, or vica-versa.

I handle dependencies with maven this way:

No matter what I turn on/off in Intellij Idea at the profiles tab, it always builds packages the same way. See the attached image.

It should work when you activate the profile using

-P

by using

mvn -Plwjgl-natives-linux <lifecycle-phase>

or

mvn -Plwjgl-natives-windows <lifecycle-phase>

.
This project ( https://github.com/LWJGL/lwjgl3-demos/blob/master/pom.xml ) uses the same os profile activation and the natives (i.e. the active profile) can be overwritten using the -P mvn switch.

It worked, thx!

Didn't want to open a new topic, I got this on windows:

[ERROR] Failed to execute goal on project engine: Could not resolve dependencies for project xy:jar:1.0-SNAPSHOT: Could not find artifact org.lwjgl:lwjgl-vulkan:jar:natives-windows:3.2.1-20181014.235349-6 in sonatype-snapshots (https://oss.sonatype.org/content/repositories/snapshots) -> [Help 1]

Command was:

mvn -Plwjgl-natives-windows compile

Tried to run on windows and on osx, same error. Compilation for linux and macos works fine.

OK, one more:

java.lang.IllegalAccessError: class org.lwjgl.vulkan.VkApplicationInfo (in module org.lwjgl.vulkan) cannot access class sun.misc.Unsafe (in module jdk.unsupported) because module org.lwjgl.vulkan does not read module jdk.unsupported

First error: the Vulkan bindings do not have a natives artifact.

Second error: This is a problem with the latest 3.2.1 snapshot, I'll try to find a solution soon.

[mudlee]

Thanks!

Regarding to the first error: after mvn clean, it happened for all platforms, and then I added the required natives and then the I got the second. Sometimes maven and/or intellij do really weird caches...

[spasi]

The second error should be fixed in 3.2.1 snapshot 6.

[mudlee]

The module visibility error gone, thx. However I have the same problem now with the natives:

[ERROR] Failed to execute goal on project engine: Could not resolve dependencies for project xy:jar:1.0-SNAPSHOT: Could not find artifact org.lwjgl:lwjgl-vulkan:jar:natives-windows:3.2.1-SNAPSHOT in sonatype-snapshots (https://oss.sonatype.org/content/repositories/snapshots) -> [Help 1]

OSX/Linux works fine.

[spasi]

As I said above, there is no natives artifact for Vulkan on Windows/Linux. It's only necessary on macOS for the MoltenVK shared library.

[mudlee]

Ah, my bad, sorry!

A question tough. Would it be a good way if I ask the user during the installation process to install vulkan too? As on osx it will be automatic with moltenvk, on win/linux I have to rely on the os's sdk, right?

[spasi]

You do not need the Vulkan SDK to use Vulkan. On Windows & Linux, it's enough to have a GPU driver with Vulkan support installed. On macOS, MoltenVK simply requires an OS version that supports Metal (i.e. macOS 10.11 or higher).

First error: the Vulkan bindings do not have a natives artifact.

Second error: This is a problem with the latest 3.2.1 snapshot, I'll try to find a solution soon.

Your First error has not been wholly solved yet.
I download the pom.xml from here : https://www.lwjgl.org/customize
And it still contains this:
      <dependency>
         <groupId>org.lwjgl</groupId>
         <artifactId>lwjgl-vulkan</artifactId>
         <version>${lwjgl.version}</version>
         <classifier>${lwjgl.natives}</classifier>
      </dependency>
If I not happened to see the forum here I might never found out what goes wrong.
I strongly suggest you fix it when you have some spare time.
