Hi,
Looking into the first problem
.c:15542:19: error: ‘num_wepkeys’ undeclared (first use in this function) It only happens inside of #ifdef HAVE_AIRPDCAP which is defined on Windows and all the buildbots hence no one discovered the problem until now. I suspect the other problems are similar.
I'm not sure if Guys comment in the bug
"The decryption code should be supported on all platforms;" implies that we could get rid of that #ifdef
Perhaps Cmake needs to check for the availability of AIRPDCAP.
Regards
Anders
