GNU Radio out-of-tree module for the CS-330 lesson. Website: http://www.csd.uoc.gr/~hy330/

Installation

1. git clone https://github.com/surligas/gr-cs330.git
2. cd gr-cs330
3. mkdir build
4. cd build
5. cmake ..
6. make
7. sudo make install

If this is the first time you are building the gr-satnogs module run sudo ldconfig

Advanced

By default, the cs330 module will use the default installation prefix. This highly depends on the Linux distribution. You can use the CMAKE_INSTALL_PREFIX variable to alter the default installation path. E.g:

cmake -DCMAKE_INSTALL_PREFIX=/usr ..

Another common control option is the library sugffix of the Linux distribution. There are distributions like Fedora, openSUSE, e.t.c that the their 64-bit version use the lib64 folder to store the 64-bit versions of their dynamic libraries. On the other hand, distributions like Ubuntu do the exact opposite. They use lib directory for the libraries of the native architecture and place the 32-bit versions on the lib32 directory. In any case the correct library directory suffix can be specified with the LIB_SUFFIX variable. For example:

cmake -DLIB_SUFFIX=64 -DCMAKE_INSTALL_PREFIX=/usr ..

will install the libraries at the /usr/lib64 directory.

gr-cs330's Issues

Segfault from psk_demodulator

Hello,
While attempting to run the project flowgraph without any modifications whatsoever I encounter a segmentation fault which appears to originate from the PSK demodulator block. From what I gather, it's due to the indexing of output_items in psk_demodulator_impl::work(), in lib/psk_demodulator_impl.cc:735.
