[Discuss-gnuradio] Thread AssertionError and Libc++abi.dylib on Mac Transmissions

[David Greene]

Hey Folks,

I've installed the latest version of GNURadio (3.6.3) using MacPorts on a
fresh Macbook Pro running 10.8.2 using,

sudo port install gnuradio +full configure.compiler=llvm-gcc-4.2

Installation was flawless and I can receive using my USRP N210 just fine.
The problem comes when I try to transmit on my USRP. I can't pinpoint what's
causing it, but I get the following errors below when I try to transmit
through UHD. No changes to the included example (uhd_const_wave.grc) except
the IP address. Any help is appreciated, I've already tried several fresh
installs using CLANG and/or LLVM-GCC-4.2 and boost is at version 1.51.
Rebooting the USRP and/or the Mac has no effect.
