Re: [Libnifalcon-devel] using latest libnifalcon & latest libusb on OS X

[Stephen S. <rad...@gm...>]

Hi,

Something I forgot to mention is a build problem I had on OS X.  It
would error at the linking stage of the test programs.  I had to
manually do the linking, adding "-framework IOKit -framework AppKit",
and then "make" again to continue the build.  I don't know how to
configure CMake to add the frameworks automatically.

The error was complaining of undefined symbols, like:

ld: Undefined symbols:
_CFUUIDGetConstantUUIDWithBytes
_CFUUIDGetUUIDBytes
_IOCreatePlugInInterfaceForService
_IODestroyPlugInInterface
_IOIteratorIsValid
_IOIteratorNext
_IOMasterPort
_IONotificationPortCreate
_IONotificationPortDestroy
_IOObjectRelease
_IOServiceGetMatchingServices
_IOServiceMatching
/usr/bin/libtool: internal link edit command failed
