Re: [PD] using bob~ with libpd for android

I believe the Android build uses Android.mk and not the main Makefile.

Yeah, that seems to be the thing that happens. In my project folder I have the PdCore/jni/libpd/Android.mk file with build instructions.

Looking inside, I see it’s building the included externals but I think it’s

missing the LIBPD_EXTRA define which is used to tell libpd to automatically call the setup function for the externals ie. bob~, bonk~, choice, etc.

I don't see *LIBPD_EXTRA* either

Is Android Studio building libpd via the Android.mk file? I haven’t done

any Android development, so I’m not sure. If it is, you can try adding -DLIBPD_EXTRA to the end of line 38 in Android.mk and rebuilding.

This leaves me with:

"PD_CFLAGS := -DPD -DHAVE_UNISTD_H -DHAVE_LIBDL -DUSEAPI_DUMMY -w DLIBPD_EXTRA "

To build the "extra" binaries, I go to the PdCore folder on the terminal and do "~/Library/Android/sdk/ndk-bundle/ndk-build". So, when I try to build it now, I get the error: "clang: *error: *no such file or directory: 'DLIBPD_EXTRA'"

So then I tried: "PD_CFLAGS := -DPD -DHAVE_UNISTD_H -DHAVE_LIBDL -DUSEAPI_DUMMY -w *-*DLIBPD_EXTRA "

Now, when building, it does something, it seems to compile the basic internals, then I get an error. Oh, and now I see I don't have anymore the compiled .so binaries I did have before for the extra objects, so they got deleted/cleaned up somehow in this process.

This is the error I get, btw:

Also, I’ve opened an issue on GitHub: https://github.com/
