You will need cmake3 from EPEL:
yum install epel-release
yum install cmake3
There's probably other deps but I haven't tested this build from a clean image so I already had them...
There are several different tools built by the LimeSuite project that you might not care about if you just want the driver and docs. There was a wxWidgets issue in CentOS 7 that prevents the build of some GUI applications but since I don't care I just use the cmake flags to turn that off. Also, I had to explicitly turn on the documentation build.
$ git clone https://github.com/myriadrf/LimeSuite
$ cd LimeSuite
$ git checkout stable
$ mkdir builddir && cd builddir
$ cmake3 .. -DENABLE_GUI=OFF -DENABLE_API_DOXYGEN=ON
$ make -j4
$ sudo make install
$ sudo ldconfig
# enable non-root users to access usb-based devices like the LimeSDR
$ cd ../udev-rules
$ sudo ./install.sh
I thought the ldconfig step is supposed to do this but I still had to add /usr/local/lib to my library path:
$ export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
Now plug in your LimeSDR and see if you can find it:
$ LimeUtil --find
* [LimeSDR-USB, media=USB 3.0, module=FX3, addr=1d50:6108, serial=0009061C02D10A14]
You may have also built the LimeQuickTest utility which does more stuff:
$ LimeQuickTest
[ TESTING STARTED ]

Firmware version mismatch!
Expected firmware version 4, but found version 3
Follow the FW and FPGA upgrade instructions:
http://wiki.myriadrf.org/Lime_Suite#Flashing_images
Or run update on the command line: LimeUtil --update
Gateware version mismatch!
Expected gateware version 2, revision 21
But found version 2, revision 11
Follow the FW and FPGA upgrade instructions:
http://wiki.myriadrf.org/Lime_Suite#Flashing_images
Or run update on the command line: LimeUtil --update
->Device: LimeSDR-USB, media=USB 3.0, module=FX3, addr=1d50:6108, serial=0009061C02D10A14

This shows a mismatch in firmware (ARM) and gateware (FPGA) versions with this software driver since I haven't updated that in a really long time so let's do that.
This is amazingly simple if you are connected to the Internet, you simply run LimeUtil --update and it will determine what needs to be updated, downloads it and programs the device. If you're not on the Internet... then I guess look at these instructions.
When we run the test again after updating, no more warnings:
$ LimeQuickTest

Now you should be ready to build the Redhawk Device.
$ git clone https://github.com/timcardenuto/LimeSDR_FEI
$ cd LimeSDR_FEI
$ ./build.sh
$ ./build.sh install
To test the Device you can use the Redhawk IDE. NOTE: make sure you open it from the same terminal that has the LD_LIBRARY_PATH set to include the installed location of the libLimeSuite.so library (in the default case this is /usr/local/lib). Otherwise when you launch the Device it will fail to find that library. This is probably something that should be installed to the Redhawk shared library path. Also again, this library path should be part of the system path after using ldconfig... not sure why it doesn't.
$ rhide &
With the Redhawk IDE open, navigate to the REDHAWK Explorer panel > Target SDR > Devices > Right click on LimeSDR_FEI > Launch in Sandbox > cpp. This should launch the Device and show a bunch of configuration info in the Console. To Allocate a Tuner, right click on the running LimeSDR Device and select Allocate, then enter the Frequency, Bandwidth, and Sample Rate that you want.
TODO there are bugs with this. Not sure what acceptable values are and no data shows up when it says it's successful.... Probably need to update API's for both LimeSDR and Redhawk Device since it's been 2 years.
