5. Complete description of the problem
   　In QNX, I am trying to load a .so file built from a C/C++ project, and I get the following error at the call to the Structure class before loading the library created in JNA.

java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/qnx-aarch32/libjnidispatch.so) not found in resource path (/opt/niagara/bin/ext/annotations-13.0.jar:/opt/niagara/bin/ext/bcstd/bcpkix-jdk15on-1.70.jar:/opt/niagara/bin/ext/bcstd/bcprov-jdk15on-1.70.jar:/opt/niagara/bin/ext/bcstd/bctls-jdk15on-1.70.jar:/opt/niagara/bin/ext/bcstd/bcutil-jdk15on-1.70.jar:/opt/niagara/bin/ext/encoder-1.2.3.jar:/opt/niagara/bin/ext/hsm-2.0.3.jar:/opt/niagara/bin/ext/javax.servlet-api-3.1.0.jar:/opt/niagara/bin/ext/jetty-all-compact3-9.4.48.v20220622.jar:/opt/niagara/bin/ext/jose4j-0.7.11.jar:/opt/niagara/bin/ext/kotlin-stdlib-1.4.20.jar:/opt/niagara/bin/ext/kotlin-stdlib-common-1.4.20.jar:/opt/niagara/bin/ext/niagarad.jar:/opt/niagara/bin/ext/nre.jar:/opt/niagara/bin/ext/okhttp-3.14.9.jar:/opt/niagara/bin/ext/okio-2.10.0.jar:/opt/niagara/bin/ext/slf4j-api-1.8.0.jar:/opt/niagara/bin/ext/tridium-JavaMail-1.5.2.1.jar:/opt/niagara/bin/ext/tridium-activation-1.0.jar)

Yes JNA does not support QNX. To fix this, a build environment must be accessible without charge, either provided as a remotely accessible service or (prefereably) an SDK usable on other platform (again preferable on linux linux).

The readme has the following description, is it possible to build for QNX?

JNA will build on most linux-like platforms with a reasonable set of GNU tools and a JDK. See the native Makefile for native configurations that have been built and tested. If your platform is supported by libffi, then chances are you can build JNA for it.
