[odb-users] ODB on Android

[c.sell at byterefinery.de]

Hi,

IMO and according to my experience, the ODB compiler has no dependency  
on the target system, including the c/c++ libraries. After all, it is  
just a code generator. As long as it generates valid standard C++  
code, it should work on any system.

I have compiled on ealier NDKs without issues.
