Increase `net.java.dev.jna:jna` version ?

[NicoKiaru]

Hello,

Do you think it would be possible to update net.java.dev.jna:jna to version 5.6.0 (or above) ?

Best,

Nicolas

What are the breaking changes with major version 5? @NicoKiaru what functionality do you require?

The following components (and maybe more) currently use jna in their pom.xml:

• https://github.com/fiji/CPU_Meter
• https://github.com/fiji/SPIM_Registration (deprecated)
• https://github.com/preibischLab/multiview-reconstruction

Some changes possibly required:

• https://java.libhunt.com/jna-latest-version#breaking-changes

Edit:
Also, some of the above usage of JNA can maybe be replaced by https://github.com/scijava/native-lib-loader ? Don't know enough about it to judge though...

Ah! I need it for a CPU meter also:

https://github.com/BIOP/ijp-imagetoatlas/blob/master/src/main/java/ch/epfl/biop/ResourcesMonitor.java
I tested and jna is required if you want a cpu meter that (really) works on all platform. I didn't know there was already one.

However, thanks to your links, I see that jna is used in SPIM_registration to connect to CUDA. I don't know how much this function is used and how involved is the update, but for sure it's more important than a CPU meter.

So I think updating jna should be tested/done by @StephanPreibisch first in SPIM_registration, because its use of jna is more important than a CPU meter. But I'm not @StephanPreibisch has time to put in this, and since my use case is not super important, we'll probably stay this way until something more important comes up.

Thanks a lot @imagejan !

Here are the components using jna I found in a quick search:

• clij/clij-coremem
• fiji/CPU_Meter
• fiji/SPIM_Registration
• uw-loci/curvelets-imagej
• deepimagej/deepimagej-plugin
• PreibischLab/multiview-reconstruction

I would love to update this across the board, but I don't have the bandwidth to do it right now unfortunately.

@mzouink, do you want to tackle this check list with me?

We need JNA 5.7 or 5.8 for upstream aarch64 support.

JNA 5.7 introduced a lipoed fat darwin binary:
java-native-access/jna#1297

JNA 5.8 split the darwin binaries into x86_64 and aarch64 versions
java-native-access/jna#1316

We should target JNA 5.8 at minimum for stable aarch64 support.

I would substantially prefer to target the latest version, as long as we might be needing to update downstream projects anyway.

I tested PreibischLab/multiview-reconstruction with JNA 5.11.0 and it is working well. jna is used for cuda computing. So hopefully if other projects needs JNA for cuda it should be ok.

I just checked clij/clij-coremem, and it works with JNA 5.11.0. All tests passing. cc: @haesleinhuepf

<jna.version>5.11.0</jna.version>

Native.loadLibrary is deprecated but still functional. Use Native.load instead.
