Tergantung versi SD Card yang kita miliki, kadang kala GNURadio sudah terinstalasi.

Cek GNURadio

Menggunakan gnuradio-config-info 

gnuradio-config-info 

Program options: gnuradio [options]:
  -h [ --help ]         print help message
  --prefix              print gnuradio installation prefix
  --sysconfdir          print gnuradio system configuration directory
  --prefsdir            print gnuradio preferences directory
  --builddate           print gnuradio build date (RFC2822 format)
  -v [ --version ]      print gnuradio version

cek sysconf directory 

gnuradio-config-info --sysconfdir

/usr/etc

cek kapan dibuat 

gnuradio-config-info --builddate

hasilnya 

Wed, 07 Dec 2011 21:58:55

cek prefix 

gnuradio-config-info --prefix

hasilnya 

/usr

Alternatif Cara Cek

Cek menggunakan perintah 

updatedb &
locate gr-
locate gnuradio
locate usrp
locate uhd

Jika ada hasilnya maka GNURadio sudah terinstalasi. Jika tidak ada, maka GNURadio belum terinstalasi.

Compile UHD

Download

opkg remove --force-depends uhd uhd-dev uhd-examples uhd-tests
echo "/usr/local/lib" >> /etc/ld.so.conf
cd ~/src
git clone git://ettus.sourcerepo.com/ettus/uhd.git uhd.git

Compile

cd ~/src/uhd.git/host/
mkdir build
cd ~/src/uhd.git/host/build
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/arm_cortex_a8_native.cmake -DENABLE_E100=ON -DENABLE_USRP_E_UTILS=TRUE -DENABLE_USRP2=OFF -DENABLE_USRP1=OFF -DENABLE_B100=OFF ../
make
make test
make install
ldconfig

atau 

cd ~/src/uhd.git/host/
mkdir build
cd ~/src/uhd.git/host/build
cmake -DCMAKE_CXX_FLAGS:STRING="-mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -g" -DENABLE_USRP_E100=TRUE -DENABLE_E100=ON -DENABLE_USRP_E_UTILS=TRUE -DENABLE_USB=OFF -DENABLE_USRP2=OFF ../
make
make test
make install
ldconfig


Install Image 003.004.002-180-gb6bb13bc

rm -Rf /usr/share/uhd/images/*
rm -Rf /usr/local/share/uhd/images/*
cd ~
tar zxvf uhd-images_003.004.002-180-gb6bb13bc.tar.gz
mv ~/uhd-images_003.004.002-180-gb6bb13bc/share/uhd/images/* /usr/local/share/uhd/images/


Perbaiki PATH

PATH=$PATH:/usr/local/bin
export PATH

Test

Test clock 52MHz 

cd /usr/local/bin
./uhd_usrp_probe --args="master_clock_rate=52e6"

Hasilnya 

linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500; UHD_003.004.003-175-g09de3c07

Test Benchmark 

cd ~/src/uhd.git/host/build/examples
./benchmark_rate --rx_rate 1000000 --tx_rate 1000000

Hasilnya kira-kira

Compile GNURadio

Untuk mengoperasikan OpenBTS di E110 kita tidak perlu menggunakan Gnuradio.



Cara ini tampaknya aman 

opkg remove --force-depends gnuradio gnuradio-dev gnuradio-examples task-gnuradio
cd ~/src
git clone git://gnuradio.org/git/gnuradio.git gnuradio.git
cd ~/src/gnuradio.git
mkdir build
cd ~/src/gnuradio.git/build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/arm_cortex_a8_native.cmake -DQT_QTCORE_INCLUDE_DIR=/usr/include/qt4/QtCore -DQT_QTGUI_INCLUDE_DIR=/usr/include/qt4/QtGui -DQT_QMAKE_EXECUTABLE=/usr/bin/qmake -DENABLE_GR_QTGUI=ON  -DQT_LIBRARY_DIR=/usr/lib -DQT_INCLUDE_DIR=/usr/include/qt4/ -DQT_MOC_EXECUTABLE=/usr/bin/moc -DQT_UIC_EXECUTABLE=/usr/bin/uic -DQT_RCC_EXECUTABLE=/usr/bin/rcc -DCMAKE_BUILD_TYPE=release  ../
make
make install
ldconfig

ALTERNATIF LAIN

buat script 

clean-build-gnuradio

Berisi 

#!/bin/sh

cd ~/src/gnuradio.git &&
rm -rf build &&
mkdir build &&
cd build &&
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/arm_cortex_a8_native.cmake -DQT_QTCORE_INCLUDE_DIR=/usr/include/qt4/QtCore -DQT_QTGUI_INCLUDE_DIR=/usr/include/qt4/QtGui -DQT_QMAKE_EXECUTABLE=/usr/bin/qmake  -DENABLE_GR_QTGUI=ON -DQT_LIBRARY_DIR=/usr/lib -DQT_INCLUDE_DIR=/usr/include/qt4/ -DQT_MOC_EXECUTABLE=/usr/bin/moc -DQT_UIC_EXECUTABLE=/usr/bin/uic -DQT_RCC_EXECUTABLE=/usr/bin/rcc -DQT_QTCORE_LIBRARY=/usr/lib/libQtCore.so -DCMAKE_BUILD_TYPE=release  ../ &&
make &&
make test &&
make install

ALTERNATIF LAIN LAGI

WARNING: Cara ini tidak bisa. Entah kenapa ./bootstrap & ./configure tidak ada. 

cd ~/src
git clone git://gnuradio.org/gnuradio.git gnuradio.git
cd ~/src/gnuradio.git
./bootstrap
./configure --enable-uhd --disable-volk --disable-usrp2 --disable-usrp1 --disable-gr-video-sdl CFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3" CXXFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3" -with-qwt-incdir=/usr/include --enable-gr-wxgui
make
make check
make install
ldconfig
