'friend' is quickly becoming an enemy.

I'm having some issues with the friend keyword...and I'm pretty sure it has to do with the C linkage that I'm forced to use. Error below, and code that generates it to follow. Each of the commented lines fail, and I'm seemingly left with the C linkage to blame...but the friend keyword has nothing to do with linkage - at all...


Toolset = Microsoft V100 (Stock with VS2010)
error C2732: linkage specification contradicts earlier specification for 'X::Java_com_A_B_C_onKeyDown'

Thanks.

PS. Never deal with JNI, instead of stack traces, you get heap dumps. :(

Try moving the function declaration above your class definition.
