Can't load library error

[Howard Lewis Ship]

I've inherited a new project and am trying to build it with jbake.

OpenJDK 64-Bit Server VM Corretto-17.0.4.9.1 (build 17.0.4.1+9-LTS, mixed mode, sharing)

jbake v2.6.7

OSX 12.6, M1

On execution :

> jbake  -b
JBake v2.6.7 (2021-05-14 21:54:29[GMT+01:00]) [http://jbake.org]

I've looked at that directory, /var/folders/yg/vytvxpw500520vzjlc899dlm0000gn/T/jna-1278838233, and it's empty.

I suspect that there may be a dependency on Intel architecture here.

If you want to reproduce, the repo is public: https://github.com/pedestal/pedestal-docs

Thanks in advance for any help!

[Howard Lewis Ship]

Others on my team have tried this; it works on Intel Macs but not M1 macs.

Have you tried to run it from an emulated x86 shell?

arch -x86_64 /bin/bash

[Howard Lewis Ship]

Just tried this ... same result.  Thanks for the idea, though.

Hm. Maybe you habe to re-install java in the emulated shell, so that you get a x86 java binary...

Hi Howard

JBake v2.6.7 uses OrientDB and the version bundled uses a version of JNA that doesn't support Apple Silicon.

Can you try v2.7.0-rc.6 instead which is available here: https://github.com/jbake-org/jbake/releases

Thanks

Jon

I'm using v2.7.0-rc.6 now and it's looking good (on my M1 Mac).
