Installing GCAM on Macbooks with M1 chips (ARM64 processor)

[niru862]

I have a Macbook Air with M1 chip that I purchased in June 2022. I followed the Youtube tutorial https://www.youtube.com/watch?v=c8DmPHHO6DA and downloaded OpenJDK version 20 macOS/x64 https://jdk.java.net/20/. I also followed user guide's "Java for Mac" section http://jgcri.github.io/gcam-doc/gcam-build.html to symlink, but I get the following error in Terminal regarding Incompatible Architecture when I run GCAM:

dyld[1679]: Library not loaded: @rpath/libjvm.dylib
Referenced from: /Users/nirajpalsule/Documents/Softwares/Global Change Assessment Model (GCAM)/gcam-v6.0-Mac-Release-Package/exe/Release/gcam
Reason: tried: '../libs/java/lib/libjvm.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '../libs/boost-lib/stage/lib/libjvm.dylib' (no such file), '../libs/libjvm.dylib' (no such file), '../libs/tbb/lib/libjvm.dylib' (no such file), '../libs/java/lib/libjvm.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '../libs/boost-lib/stage/lib/libjvm.dylib' (no such file), '../libs/libjvm.dylib' (no such file), '../libs/tbb/lib/libjvm.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS@rpath/libjvm.dylib' (no such file), '../libs/java/lib/libjvm.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '../libs/boost-lib/stage/lib/libjvm.dylib' (no such file), '../libs/libjvm.dylib' (no such file), '../libs/tbb/lib/libjvm.dylib' (no such file), '../libs/java/lib/libjvm.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '../libs/boost-lib/stage/lib/libjvm.dylib' (no such file), '../libs/libjvm.dylib' (no such file), '../libs/tbb/lib/libjvm.dylib' (no such file), '/usr/local/lib/libjvm.dylib' (no such file), '/usr/lib/libjvm.dylib' (no such file, not in dyld cache)

I understand that Macbooks have ARM64 processor (also referred to as AARCH64) instead of x64 processor since 2022. Hence, I downloaded OpenJDK macOS/AARCH64, but it does not detect any file after symlink and gives following error:

dyld[13483]: Library not loaded: @rpath/libjvm.dylib

I would appreciate if someone can guide me to resolve this issue or find a workaround to install and run gcam.
