Support aarch64

Running Intelij Community on a raspberry PI model 4 (4G) has a problem with loading pty4j and subsequently cant open terminals in the interface. This seems to be due to a lack of support for ARM 64 architecture. Intelij is fast and highly useable on Raspbian on pi4, I dont think it would be nessacary to support earlier PIs as pi4 is the first version that has suffient ram and performance to run Intelij.

Hey, I had the same issue but on macOS with an M1 processor and Android Studio Preview. The above solution works but I had to change the commands slightly. I’m sharing it here for anyone with the same issue on M1 Mac 😃.

git clone https://github.com/JetBrains/pty4j.git
cd pty4j/native
clang -fPIC -c *.c
clang -shared -o libpty.dylib *.o
cp libpty.dylib "/Applications/Android Studio Preview.app/Contents/lib/pty4j-native/darwin/"

In order to solve the problem you can simply compile the library yourself, for example for aarch4:

• pty4j/native
• gcc -fPIC -c *.c
• gcc -shared -o libpty.so *.o
• cp libpty.so /opt/idea-IC/lib/pty4j-native/linux/x86_64/libpty.so

Note that IntelliJ look for the library in x86_64 folder even if we are under aarch4 😃
