Hi guys, Regarding GDB and Python:
I've got some WIP Python patches that were created for Necessitas Qt Creator's NDK GDB for Android. They've since been merged into the Google NDK: https://android-review.googlesource.com/#/c/38501/ Using the patches in that merge request, it's possible to build Python (and then GDB with that Python) using mingw-w64 (on Linux so far, MSYS build is WIP) for both win32 and win64. The patch also generates a shell script to replace python-config (which unfortunately uses Python) so that GDB can pick up the right configuration details automatically when used in a cross compilation setting. The only missing part is setting PYTHONHOME env. var from within GDB. The attached (and pretty horribly complicated) patch gives an example of how this is done in the context of the NDK (I needed to do lots of guess work and probing as I'm not sure what the final relative layout will be- it should be as easy as calling GetModuleFileName and stripping off some path elements). Cheers, Ray. p.s. There's patches for Python 3.3.0b as well in http://mingw-and-ndk.googlecode.com/files/python-273-and-330b1-patches-WIP.7z p.p.s. There's built Android NDKs that use this on my googlecode site as well.
