Cross-compiling for Aarch64 #93

Open Desperado17 opened 1 year ago

Desperado17 commented 1 year ago

Greetings,

I want to cross-compile this for an Aarch64 Poky Linux target using a toolchain that supplies among others aarch64-linux-gnu-g++. The target itself has a JRE in a preset path for which I could obtain the corresponding JDK both for Aarch64 and the corresponding version for host Linux that would conduct the compile.

Is there a manual somewhere on how to achieve this?

Regards

An alternative path might be to setup an aarch root or docker multiarch setup and compile using qemu emulation instead of setting up a cross compilation tool chain.

That said, since this is a standard cmake project any General instructions about cross compilation might just apply.

Just in theory:

If it has a JAVA_ROOT and a g++ it should be fine, yes?

Ok, I successfully built attach-main.jar and libperfmap.so for the target. Now, how do I deploy these? I understand that I have to combine them somehow with the contents of /bin but how? I don't understand the manual completely in that regard.
