Thanks for the reply. I tried the CMake approach following the steps you 
mentioned but received an error when building.  
First, I created CMakeLists which is pretty simple as shown below

cmake_minimum_required(VERSION 3.10)

#set the project name
project(Tutorial)

#add the executable
add_executable(replay_example rfnoc_replay_samples_1_from_file.cpp)

Then, I sourced the file, and set the flag for CMake. Lastly, inside of a build 
directory, I tried building the App and got the following printout 

/usr/local/share/uhd/images/y/sysroots/x86_64-oesdk-linux/usr/libexec/arm-oe-linux-gnueabi/gcc/arm-oe-linux-gnueabi/9.2.0/real-ld:

I'm not sure if this is a boost issue or something else.

 Hi Tellrell,
Do not use the Xilinx SDK, only the Yocto one, i.e. 
/usr/local/share/uhd/images/y/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi
You need to source the "environment-setup-cortexa9t2hf-neon-oe-linux-gnueabi" 
file before cross compiling. If you use cmake with building your application, 
you also need to set the flag "-DCMAKE_TOOLCHAIN_FILE=<path to 
UHD>/host/cmake/Toolchains/oe-sdk_cross.cmake".
Also, if you just want to run the UHD example, it already exists on the N310's 
root file system at: /usr/lib/uhd/examples/rfnoc_replay_samples_from_file

 I'm trying to compile the source code using SDK 2019.1. I'm pointing the the 
SDK project to the directory for sysroot and also to the directory for my linux 
toolchain which are the following
 /usr/local/share/uhd/images/y/sysroots/cortexa9t2hf-neon-oe-linux-gnueabi

/tools/Xilinx/SDK/2019.1/gnu/aarch32/lin/gcc-arm-linux-gnueabi/arm-linux-gnueabihf
I continue to get the following error stating that these files can't be found, 
however, they do exist. And, when I try adding them within the project and 
refreshing nothing happens. 


cannot find /lib/ld-linux-armhf.so.3   

cannot find /lib/libc.so.6    

cannot find /usr/lib/libc_nonshared.a    

Am I going about building this application correctly? I thought that linking my 
project to sysroot which I installed for the n310 and to the SDK toolchain( 
maybe I'm doing this incorrectly) would be pretty straightforward.

 Yep. Marcus you caught it!! That worked. Do I need to complete the sections on 
"Compiling MPM Natively" and "Building UHD"?? I understand that I need the 
cross-compiler for compiling SW for the device but I don't see the need for 
completing the other two parts. Is there something additional that needs to be 
done other than cross compiling on the host machine and ssh'ing over the 
executable? 
  
  As far as I know, you should be able to just cross-compile the code you're 
interested in.
