Marble on android compilation problem

[Dennis Nienhüser]

Hi Jean,

thanks for the nice mail with detailled information, appreciated.

I don't see any hardcoded arm values neither in Marble nor in the 
Android toolchain from extra-cmake-modules. I wonder if the problem 
originates from an early cmake call where not all x86 values had been 
set. Can you run 'make rebuild_cache' in the build directory and test if 
that makes linking work afterwards?

Regards,
Dennis
