Hi

Im trying to build GnuRadio on OS X 10.9.2 Im assuming the "Undefined  
symbols for architecture x86\_64 is related to some mismatch in  
libraries. Could somebody please offer some suggestions on how to debug  
the issue. The last few lines of the build are:

Hi Shane - With just the information provided, given that CMake is  
trying to link against CppUnit means that that library was found  
somewhere. Hence, chances are that CppUnit is being linked to libstdc++  
while GNU Radio is trying to use libc++ – the different C++ runtime  
libraries tend to generate these sorts of errors. There is a small  
chance that CppUnit was compiled for the wrong architecture (e.g.,  
x86\_32 [i386], PPC, or PPC\_64), but I think the different C++ runtime  
library is more likely. If you want more help on this, email me  
off-list and we can summarize once we figure out the actual issue(s). -
