thanks sir

can you explain it more clearly?sorry for not familiar with it. 

I just copy the "volk":(it can not work also)

I don't use the MacPorts, just follow the instruction from GitHub.Namely, build by myself.

The issue is that gr-lte requires Volk but does not check for it -- nor use its API / headers correctly nor use its ABI / libraries correctly -- in the CMakeLists.txt scripts. This is a simple fix, which you can copy from other OOT modules.

Related: Are you trying to use MacPorts to do the install? I've thought about adding gr-lte into MP for a while. Would not be difficult for me to do so, along with patching this issue, so that installing it is as simple as "sudo port install gr-lte" ... - MLD

I want to install gr-lte and learn something about LTE. And I follow the instruction from https://github.com/kit-cel/gr-lte.

when the go to the command "make -jX", it go wrong.

The error message:

Linking CXX shared library libgnuradio-lte.dylib

Undefined symbols for architecture x86_64:

Have someone met this problem? Thanks very much.
