Re: [equinox-dev] Native code on Windows 10

Thu, 28 Jan 2021 06:20:00 -0800

To be clear, the Eclipse IDE doesn't support x86 32-bit.  Nothing in the Equinox Framework prevents you from running on x86 32-bit.
 
Can you run the gogo console in your environment and run the following command?

inspect capability osgi.native 0
 
I expect output like this (note this is from my Mac so it will be different on Windows):
 
org.eclipse.osgi_3.16.200.v20201209-1827 [0] provides:
------------------------------------------------------
osgi.native with properties:
   osgi.native.language = en
   osgi.native.osname = [MacOSX, Mac OS X]
   osgi.native.osversion = 10.14.6
   osgi.native.processor = [x86-64, amd64, em64t, x86_64]
 
 
Note that there will be several other properties.  But the osgi.native ones are what is used to match the Bundle-Native code header.
 
Also, can we have a look at your requirement for the osgi.native namespace?  Use this command, with the bundle ID of the your bundle with the Bundle-NativeCode header:
 

inspect requirement osgi.native <your bundle ID>

This should give the transformed requirement filter the framework derived from your Bundle-Native code header which is then matched against the osgi.native capability provided by the framework.

OK, I didn’t know that x86 support was dropped for Windows. The application used to work with previous equinox versions. Since we don’t really use Windows, this gets tested once every 2 years :-)
 
Isn’t it just better to throw an exception “equinox does not run on Windows x86" and exit?
 
Also: what do you mean by resolve?
 
We don’t use bnd but we get an exception like this:
 
Unresolved requirement: Require-Capability: osgi.native
 
Thank you,
Todor

Hi Todor,
 
I also suspect you use at least the wrong architecture name. The available names can be found under: https://docs.osgi.org/reference/osnames.html
 
Also: what do you mean by resolve? If you use the bnd resolver, you have to make sure you provide the native capabilities to the resolver. Here you need to add: -runsystemcapabilities: ${native_capability} if I'm not mistaken.
 
Regards,
 
Jürgen.

Hi Todor,
 
I am not sure if there is special/different support in Equinox, so my answer may be off base.
 
You are using 32-bit Windows - however 32-bit has not been supported by Eclipse since Eclipse 4.10 (2018-12) release. Could that be your problem here?

Hello,
 
I have a problem resolving native code on Windows 10. The following manifest declaration does not work:
 
Bundle-NativeCode: sqlite-native/windows/x86/sqlitejdbc.dll; processor=x86; osname=win32
 
whereas removing 'processor' and 'osname' seems to solve the problem, i.e.
 
Bundle-NativeCode: sqlite-native/windows/x86/sqlitejdbc.dll
 
I've tried specifying the 'org.osgi.framework.processor' and 'org.osgi.framework.os.name' like so:
 
-Dorg.osgi.framework.processor=x86 -Dorg.osgi.framework.os.name=win32
 
Any ideas? I'm using the following environment:
 
Windows 10 32-bit
Oracle Java 1.8.0_281
Eclipse 4.16 / Equinox 3.20.200.v20200528-0603
 
Thanks in advance,
Todor
