Support Apple M1 chips.

[syhily]

no linker is defined in the aol.properties file for 'aarch64.MacOSX.linker'

[mondain]

@syhily it's pretty simple to add other entries in the aol.properties file; I'm sure the maintainers would appreciate a patch / PR, if you or anyone else do the leg-work on this support.

@syhily I added this section to my aol.properties file for M1

To use a custom aol properties file, you have to set a property like this in your pom.xml:

<nar.aolProperties>${project.basedir}/aol.properties</nar.aolProperties>

Or pass it as -D${project.basedir}/aol.properties replace the project basedir with your path

Oddly, I just noticed this after I found my c++ / dylib didn't get compiled. Nothing that I do seems to get it to find my c++ source.

[INFO] --- nar-maven-plugin:3.10.1:nar-compile (default-nar-compile) @ red5pro-cauldron ---
[INFO] Nothing to compile

Ideas?

I ran with -X and I can see that it indeed knows my forced sourceDirectory

@syhily @GregDomjan So it seems there's quite a bit more to this whole Mac M1 thing; I've looked through all the relevant classes for doing the compilation in the nar-plugin, but nothing seems out of the ordinary and everything still works with my builds on a non-M1 Mac. It seems that clang takes over for gcc/g++ on the M1 and does not compile as expected and I'm not sure how to remedy that with the nar-plugin. What I have had to do is skip the nar-plugin for my native compile step and use g++ directly from a script and not the clang g++ configuration that is set up by Apple on the M1, but the brew version instead. That all being said, if we could configure the nar-plugin compile goal to use a different g++ install, it may work again for this work-around of Apple's bullshit. Ping me back if anyone else is interested in this stuff...

@mondain I had the same problem but could fix it by replacing g++ with gpp, in addition I had to add include/darwin. So for me with only C it looks like this:

aarch64.MacOSX.linker=g++

aarch64.MacOSX.gpp.c.compiler=gcc
aarch64.MacOSX.gpp.c.defines=Darwin GNU_GCC 
aarch64.MacOSX.gpp.c.options=-Wall -Wno-long-long -Wpointer-arith -Wconversion
aarch64.MacOSX.gpp.c.includes=**/*.c
aarch64.MacOSX.gpp.c.excludes=

aarch64.MacOSX.gpp.java.include=include;include/darwin
aarch64.MacOSX.gpp.java.runtimeDirectory=IGNORED

aarch64.MacOSX.gpp.lib.prefix=lib
aarch64.MacOSX.gpp.shared.prefix=lib
aarch64.MacOSX.gpp.static.extension=a
aarch64.MacOSX.gpp.shared.extension=dylib
aarch64.MacOSX.gpp.plugin.extension=bundle
aarch64.MacOSX.gpp.jni.extension=jnilib
aarch64.MacOSX.gpp.executable.extension=

Hi,
I tried the method suggested by @mondain above, & passed the aol.properties file like this: -Dconf/aol.properties, but this doesn't seem to be picked up.

& the process till bails out with:

Caused by: java.lang.RuntimeException: Unhandled architecture/OS: aarch64-MacOSX
	at org.newsclub.net.unix.NarSystem.getAOLs(NarSystem.java:110)
	at org.newsclub.net.unix.NarSystem.loadLibrary(NarSystem.java:30)
	... 44 more

Any ideas on this?
