OSX Build Error - kernelrecord.cpp:79:24: error: call to 'pow' is ambiguous #116

Closed brossi closed 10 years ago

brossi commented 10 years ago

The master branch is generating a compile error on OSX. I haven't had a chance to dig in deeper, so this may be a simple fix, but I wanted to put this out there in case someone had a chance to take a look.

I'll try to get to it in the morning so we can wrap up the 0.1.1 build and get it released.

Awesome, thank you @thokon00 . I'll get those suggestions integrated and tested. I really appreciate it.

brossi commented 10 years ago

That fixed it. Running tests now to confirm that there aren't any other issues.
