Building and installing SDRangel for Windows

Introduction, limitations, warnings...

This is new in version 1.1.3 and also experimental. Use at your own risk! This may or may not work on your machine and version of Windows. It was tested more or less successfully in native Windows 7, 8 and 10 however it does not work in a Virtualbox guest supposedly because it uses OpenGL ES 2.0 instead of the OpenGL desktop version (OpenGL 4.3) when it is running native and I think the OpenGL code in SDRangel is still not quite right to be compatible with the ES version (use of QtGLWidget instead of QtOpenGLWidget).

You should take note that the Windows scheduler is just a piece of crap and not suitable for near real time applications like SDRs. In any case you should make sure that the sdrangel.exe process does not take more than 35% of the global CPU (check this with Task Manager). Unload channel plugins if necessary. Promoting sdrangel.exe process to real time via Task Manager may or may not help but usually not. If you encounter any problem just grab a Linux installation CD or .iso file and get yourself a decent OS first. You have been warned!

There are no plugins for both flavours of Funcubes since it uses Alsa interface which is Linux exclusively. Changing for the Qt audio portable interface instead could be a solution that will be investigated in the future.

The SDRdaemon plug-in is present only in the 64 bit build version since version 1.1.4. The messaging system based on nanomsg works only in the 64 bit environment. However please be aware that the SDRdaemon plugin is not working well mainly due to the fact that it needs an OS with a decent scheduler and Windows is definitely not this sort of OS (see my previous warning). In fact depending on the case your mileage may vary however the Linux version works always beautifully so you know the options if you really want to use it!

Build environment

You will have to use QtCreator and its environment for that purpose. Build was done with the Desktop_Qt_5_5_1_MinGW_32bit tool-chain. Some other flavors might work. Please refer to Qt documentation for Qt Creator details.

You will need to add CONFIG+=MINGW32 to the qmake options. In QtCreator open the Projects menu (the file icon on the left bar) and in the Build steps section open the qmake details collapsed section (click on the caret icon). Choose the build configuration for which you run the build (debug or release) and add CONFIG+=MINGW32 to the Additional arguments line.

Dependencies

Boost

You only really need the Boost headers so there is no need to compile Boost itself. Just download an archive from the Boost website and unpack it somewhere. In our example it will be installed in D:\boost_1_58_0.

You then need to update the .pro files that depend on Boost. They are:

  • sdrbase\sdrbase.pro
  • plugins\channel\chanalyzer\chanalyzer.pro

Just update the following line with the location of your Boost installation:

  • CONFIG(MINGW32):INCLUDEPATH += "D:\boost_1_58_0"

USB support (libusb)

You have to download an archive of libusb that supports MinGW32 from the following location. You will have the choice among various versions and various archive formats in each version folder. It works with version 1.0.20. In our example it will be installed in D:\softs\libusb-1.0.20.

You then need to update the .pro files that depend on libusb. They are:

  • libairspy\libairspy.pro
  • libhackrf\libhackrf.pro
  • librtlsdr\librtlsdr.pro
  • libbladerf\libbladerf.pro

Just update the following lines with the location of your libusb installation:

  • CONFIG(MINGW32):INCLUDEPATH += "D:\softs\libusb-1.0.20\include\libusb-1.0"
  • CONFIG(MINGW32):LIBS += -LD:\softs\libusb-1.0.20\MinGW32\dll -llibusb-1.0

Airspy library (libairspy)

Download the source code or clone the git repository somewhere. It our example it will be installed in D:\softs\libairspy. Copy the header files (*.h) from D:\softs\libairspy\libairspy\src to the directory above (D:\softs\libairspy\libairspy).

You then need to update the .pro files that depend on libairspy. They are:

  • libairspy\libairspy.pro. Update the following line with the location of your libiarspy installation:
    • CONFIG(MINGW32):LIBAIRSPYSRC = "D:\softs\libairspy\libairspy"
  • plugins\samplesource\airspy\airspy.pro. Update the following line with the location of your libiarspy installation:
    • CONFIG(MINGW32):LIBAIRSPYSRC = "D:\softs\libairspy"

HackRF library (libhackrf)

Download the source code or clone the git repository somewhere. It our example it will be installed in D:\softs\hackrf. Copy the header files (*.h) from D:\softs\hackrf\host\libhackrf\src to the directory above (D:\softs\hackrf\host\libhackrf).

You then need to update the .pro files that depend on libhackrf. They are:

  • libhackrf\libhackrf.pro. Update the following line with the location of your libhackrf installation:
    • CONFIG(MINGW32):LIBHACKRFSRC = "D:\softs\hackrf\host\libhackrf"
  • plugins\samplesource\hackrf\hackrf.pro. Update the following line with the location of your libhackrf installation:
    • CONFIG(MINGW32):LIBHACKRFSRC = "D:\softs\hackrf\host"

RTL-SDR library (librtlsdr)

Download the source code or clone the git repository somewhere. It our example it will be installed in D:\softs\librtlsdr.

You then need to update the .pro files that depend on librtlsdr. They are:

  • librtlsdr\librtlsdr.pro. Update the following line with the location of your librtlsdr installation:
    • CONFIG(MINGW32):LIBRTLSDRSRC = "D:\softs\librtlsdr"
  • plugins\samplesource\rtlsdr\rtlsdr.pro. Update the following line with the location of your librtlsdr installation:
    • CONFIG(MINGW32):LIBRTLSDRSRC = "D:\softs\librtlsdr"

BladeRF library (libbladerf)

You need to download the 1.5.1 version specifically that is found here. Unzip it somewhere say in D:\softs So it will be installed in D:\softs\bladeRF-libbladeRF_v1.5.1. If your installation directory is different you need to update the dependent .pro files:

  • libbladerf\libbladerf.pro, update the following lines with the location of your bladeRF installation:
    • CONFIG(MINGW32):LIBBLADERFSRC = "D:\softs\bladeRF-libbladeRF_v1.5.1"
    • CONFIG(MINGW32):LIBBLADERFCOMMONSRC = "D:\softs\bladeRF-libbladeRF_v1.5.1\host\common"
    • CONFIG(MINGW32):LIBBLADERFLIBSRC = "D:\softs\bladeRF-libbladeRF_v1.5.1\host\libraries\libbladeRF"
  • plugins\samplesource\bladerf\bladerf.pro. Update the following line with the location of your BladeRF installation:
    • CONFIG(MINGW32):LIBBLADERFSRC = "D:\softs\bladeRF\host\libraries\libbladeRF\include"

Dependencies for DSD (Digital Speech Decoding) plugin

mbelib

You need to clone the mbelib git repository. Let's say you have cloned it to D:\softs\mbelib. If your cloned repository is different you will need to update the dependent .pro files:

  • mbelib\mbelib.pro
  • dsdcc\dscc.pro
  • plugins\channel\demoddsd\demodsd.pro

Changing the following lines:

CONFIG(MINGW32):LIBMBELIBSRC = "D:\softs\mbelib" CONFIG(MINGW64):LIBMBELIBSRC = "D:\softs\mbelib"

DSDcc

You need to clone the DSDcc git repository. Let's say you have cloned it to D:\softs\dsdcc. If your cloned repository is different you will need to update the dependent .pro files:

  • dsdcc\dscc.pro
  • plugins\channel\demoddsd\demodsd.pro

Changing the following lines:

CONFIG(MINGW32):LIBDSDCCSRC = "D:\softs\dsdcc" CONFIG(MINGW64):LIBDSDCCSRC = "D:\softs\dsdcc"

Build

Basically you open the project in QtCreator by selecting the sdrangel.windows.pro file in the source root directory and run the build command from the menu. This will eventually produce the sdrangel.exe executable and dependent library and plug-in DLLs in various parts of the build directory. See the Installation paragraph next for details on installing all files in a single place.

Installation

Then comes the tedious part of packaging everything in a single place so that you will just have to click on sdrangel.exe in the file explorer to start. Please follow the next steps for this purpose.

  • Make yourself an installation directory say D:\Programs\sdrangel
  • Assume the build directory is D:\development\build-sdrangel.windows-Desktop_Qt_5_5_1_MinGW_32bit-Release (assuming you compiled SDRangel for release)
  • Assume the source directory is D:\development\sdrangel
  • From the Qt group in the Windows start menu select the Qt 5.5 for Desktop (Mingw... console box
  • In this console type: bin\windeployqt.exe --dir D:\Programs\sdrangel D:\development\build-sdrangel.windows-Desktop_Qt_5_5_1_MinGW_32bit-Release\app\release\sdrangel.exe D:\development\build-sdrangel.windows-Desktop_Qt_5_5_1_MinGW_32bit-Release\sdrbase\release\sdrbase.dll
  • This copies all dependencies for Qt but alas nothing from our software so you will have to do this yourself. In the same console cd to the root of the build directory and type:
    • D:\development\sdrangel\windows.install.bat release D:\Programs\sdrangel
    • use debug in the place of release if you built the debug version

Running

You will need to install Zadig to get USB support for hardware devices. Please refer to Zadig website for details. Basically if you get things working for SDR# or HDSDR then it will work with SDRangel.

MinGW64 tool-chain

It is possible to use a MinGW64 tool-chain by following these steps:

  • Install MSys2 from this page. Follow all the steps.
  • Install Qt5 from MSys2 command line:
    • pacman -Sy mingw-w64-x86_64-qt5
  • Install gcc/g++ from MSys2 command line:
    • pacman -Sy mingw64/mingw-w64-x86_64-gcc
  • Create a new "kit" in Qt Creator:
    • Go to "Projects" sub-menu from the left menu bar
    • Click on "Manage kits"
    • In "Compilers" tab add a compiler naming it "MinGW64" for example. In the compiler path specify the path to g++ in your MSys2 installation (ex: D:\msys64\mingw64\bin\g++.exe)
    • In "Qt versions" tab add a Qt version and specify the path to the qmake.exe in your MSys2 installation (ex: D:\msys64\mingw64\bin\qmake.exe)
    • In "Kits" tab add a new kit and name it "MinGW64" for example.
      • In "Compiler" select the "MinGW64" compiler you created previously
      • In "Qt version" select the Qt version you created previously
    • You should now be able to use this "kit" for your build
    • In the "Build steps" section add CONFIG+=MINGW64 in the "Additional arguments"

Use the windeployqt.exe of the MSys2 distribution to copy the base files to your target installation directory in a similar way as this is done for MinGW32 (see above).

The final packaging is done with the windows64.install.bat utility. Assuming D:\development\sdrangel is the root directory of your cloned source repository, D:\msys64 is the installation directory of MSys2, D:\softs\libusb-1.0.20\MinGW64 is your libusb installation directory and D:\Programs\sdrangel64 is your target installation directory do: D:\development\sdrangel\windows64.install.bat release D:\Programs\sdrangel. Modify the script if your MSys2 and libusb locations are different.
