C++ Purecap Cross compile

Sam Dudley over 1 year ago

Hi All,

I'm wondering what the best way to compile purecap c++ applications is?

Currently I'm running Android nano on the development board following the instructions in the user guide. I have successfully compiled c applications using the musl c library but now have a dependency on a c++ application.

I can't find a purecap libc++ within the morello_workspace. Is there a library available?

Thanks,

Sam.

Hi Sam, In combination with Android nano, it might be easiest to use the Pure-cap support and libraries which are integrated in the Android/Morello already i.e. Bionic standard C library etc. The base...

I'm happy to try Android/Morello.
Would this require swapping to a Blueprint / soong build?

Indeed, that's correct.

In addition to the ported Android components, there is a trivial example available at https://git.morello-project.org/morello/android/vendor/arm/morello-examples/-/tree/morello/mainline/hello-morello (part of the Android/Morello tree)

Related document is available at: https://git.morello-project.org/morello/docs/-/blob/morello/mainline/android-porting-guidelines.rst

This example is in C, however in the same way it is possible to add *.cpp sources.

More general user-guide on setting up nano Android/Morello environment is available at https://git.morello-project.org/morello/docs/-/blob/morello/mainline/user-guide.rst

The latest available documentation on the Android/Morello porting status is located at https://git.morello-project.org/morello/docs/-/blob/morello/mainline/android-readme.rst (these days, it is updated approximately on a quarterly basis)

One notable limitation in C++ support in Android/Morello - the C++ exceptions aren't supported yet.
