After installation, I tried Testing. but I got error messages as follows: I checked "Common compile and runtime errors" in wiki. all yes except site-packages, lora module is in dist-packages. files in lora directory:

/usr/local/lib/python2.7/dist-packages/lora$ ls

__init__.pyo  lora_decoder.pyo  lora_receiver.pyo  message_wireshark_sink.pyo

Error message:

Hi, thanks for reporting! I presume that something went wrong during the installation of the library. I tried reinstalling on a clean VM and didn't encounter your issue. Could you post your build log if possible?

Hi, Thank you for the quick response.

Is this enough for checking.

If you need more info, let me know. Thank you again.

Looks like your Python libraries might be installed in /usr/lib, while gr-lora was installed in /usr/local/lib. You can try running cmake ../ -DCMAKE_INSTALL_PREFIX=/usr followed by make and sudo make install.

Alternatively, you can add the directory to which the gr-lora Python modules were installed to your PYTHONPATH enviroment variable.

Hi, Thank you for your quick response.

I tried cmake ../ -DCMAKE_INSTALL_PREFIX=/usr , make, make install and sudo ldconfig. But, nothing changed except modules were installed in /usr/lib directory.

which directory should channelizer related module be ? could you teach me the name of channelizer related modules? I think something wrong with swig related portions in my case.

Yes, you are right. The issue appears to be SWIG related as your log file reads -- Disabling SWIG because version check failed. Could you please post the output of $ swig -version?

ty4tw commented 7 years ago

2 swig packages were found swig and swig. but not installed. so, did $ sudo apt install swig swig version is version 3.0.8.

retry but another error occcured.

Not sure what the issue is here. Perhaps you don't have gnuradio-dev installed? On a clean Ubuntu (Trusty) machine, you can perform the following steps to install gr-lora:

    sudo apt-get update
    sudo apt-get install g++-4.8
    export CXX="g++-4.8"
    export CC="gcc-4.8"
    sudo pip install scipy
    sudo apt-get install swig
    sudo apt-get install libcppunit-dev
    sudo apt-get install fftw3 fftw-dev libfftw3-dev
    sudo apt-get install libboost1.55-all-dev
    sudo apt-get install gnuradio
    sudo apt-get install gnuradio-dev
    sudo apt-get install liblog4cpp5
    sudo apt-get install liblog4cpp5-dev
    sudo ldconfig
    git clone https://github.com/jgaeddert/liquid-dsp.git
    cd liquid-dsp/
    sudo sh ./bootstrap.sh
    sh ./configure
    make && sudo make install
    sudo ldconfig
    cd ../
    cd gr-lora
    mkdir build && cd build
    cmake ../
    make
    sudo make install

If you have a version older than Trusty, gr-lora is not supported unfortunately.

ty4tw commented 7 years ago

Thank you for your support. I made it. I uninstalled gnuradio related modules and installed again. Every thing works fine. I think that the installation process of gnuradion had problems. I did as follows: ( add --recursive option this time)

git clone --recursive http://git.gnuradio.org/git/gnuradio.git
 sudo install cheetah
cd gnuradio
 mkdir build
 cd build/
 cmake ../
 make
 make test
 sudo make install
 sudo ldconfig

 cd ../../
 sudo apt-get remove gr-osmosdr
 sudo apt-get update
 sudo apt-get install gr-osmosdr
 git clone git://git.osmocom.org/gr-osmosdr
 cd gr-osmosdr/
 mkdir build
 cd build/
 cmake ../
 make
 sudo make install
 sudo ldconfig

cd ../../
git clone https://github.com/rpp0/gr-lora.git
cd gr-lora
mkdir build
cd build
cmake ../
make
sudo make install
make test
sudo make install
sudo ldconfig

@rpp0 I followed those installation steps on a clean Trusty VM , knowing that the available gnuradio version is 3.7.2 . But when i run the python test script lora_receive_file_nogui.py , i get the following error : error lora gnuradio3 7 2 - copie

And according to the discussion in issue #14 : to avoid this error we need at least GNU Radio version 3.7.9 .
