[PROJ] Proj9 for ARM/Android

[Bert Huijben]

I know proj builds and works on arm, but I don’t know of anybody providing ready to use binaries for Android.

 �

I know first hand that it works on Linux ARM64 (Vcpkg has this in their package system) and Windows ARM64 (I cross build this version for SharpProj, and it had some limited tesing), but I don’t think that helps you.

 �

The CMake system of proj should just work for that platform, but then you need to somehow expose the apis for jni.

Hello,

 �

Are there any plans or experiences to compile Proj9 for ARM systems? We would like to integrate Proj9 into our Android app and have so far only found implementations based on Proj4 on the internet. 

 �

We want to access the Proj9 library via Android JNI. Mainly we need the functions of the cs2cs module. 

 �

Since we have already built Proj9 for x64, we know that other external libraries are also created during this process. Do you have any experience if these external libraries exist or are compilable for ARM systems?

 �

Thanks in advance
