It looks like qt4 was not included in the cross-compile build. If I look at my working e300 cross-compile, I have a folder: /opt/gnuradio/e300/sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/include/qt4/ (in fact, there is a tone of stuff in that include). If I look in the N310 directory, it doesn't exist: /opt/gnuradio/N310/sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/include/ (and there are very few files/folders in there at all. I will look into building it by hand, but I am guessing that it will just lead to more things needing to be cross-compiled.... --------- Original Message --------- Subject: RE: cross-compiling for N310 From: "Jason Matusiak" <ja...@gardettoengineering.com> Date: 12/17/18 3:15 pm To: "Ettus Mail List" <usrp-users@lists.ettus.com>
OK, I see the first mistake. I was copying-and-pasting my notes for the E310 which had a different sysroot. Once I made the change to the proper one, it seems like it got past the rfnoc issue (or I haven't hit it yet with this new error). I am not getting: - Found PkgConfig: /opt/gnuradio/N310/sysroots/x86_64-oesdk-linux/usr/bin/pkg-config (found version "0.29.2") -- Found UHD: /opt/gnuradio/N310/sysroots/cortexa9hf-neon-oe-linux-gnueabi/usr/lib/libuhd.so -- Found PythonLibs: /opt/gnuradio/N310/sysroots/cortexa9hf-neon-oe-linux-gnueabi/usr/lib/libpython2.7.so (found suitable version "2.7.14", minimum required is "2") CMake Warning at /opt/gnuradio/N310/sysroots/x86_64-oesdk-linux/usr/share/cmake-3.10/Modules/FindQt4.cmake:620 (message): /usr/bin/qmake-qt4 reported QT_INSTALL_LIBS as "/usr/lib64" but QtCore could not be found there.

I feel like I had this issue before with an E310 build and Phil B had to make mods to the toolchain. Has anyone else seen and got around this? --------- Original Message --------- Subject: cross-compiling for N310 From: "Jason Matusiak" <ja...@gardettoengineering.com> Date: 12/17/18 1:35 pm To: "Ettus Mail List" <usrp-users@lists.ettus.com> Has anyone successfully created a new build for an N310 (RFNoC version in particular)? I was going to bring it up to date, but seem to be having issues. I ran: uhd_images_downloader -t sdimg -v To get the *.sh image for cross-compiling: oecore-x86_64-cortexa9hf-neon-toolchain-nodistro.0.sh I then install it like I do for the E310. I create a src directory and pull down uhd and its sub-module fpga-src. I've tried main, master, and UHD-3.13, and they all build fine, but give me issues later on. In my cmake I make sure to have -DENABLE_RFNOC=ON and I see it checked when I run cmake-gui. I then pull down gnuradio, and build like I normally do. Lastly, I pull down gr-ettus. When I run: cmake -DCMAKE_TOOLCHAIN_FILE=$PREFIX/src/gnuradio/cmake/Toolchains/oe-sdk_cross.cmake -DENABLE_DOXYGEN=OFF -DCMAKE_INSTALL_PREFIX=/usr .. It mostly works and then errors out with: -- Found PkgConfig: /opt/gnuradio/N310/sysroots/x86_64-oesdk-linux/usr/bin/pkg-config (found version "0.29.2") -- Found UHD: /opt/gnuradio/N310/sysroots/cortexa9hf-neon-oe-linux-gnueabi/usr/lib/libuhd.so CMake Error at CMakeLists.txt:140 (message): RFNoC not found. -- Configuring incomplete, errors occurred!

In the past, I thought that that usually means uhd was not built properly to have RFNoC enabled, but it looks to me like it is here. Anyone happen to see what I am missing here?
