Re: [Discuss-gnuradio] Creating OOT module

[Marcus Müller]

Hi Sreena,

1. have you added your block using gr_modtool? otherwise, cmake won't notice it's there.
2. if you have, what version of GNU Radio are you using? Support for python-only OOT modules have but recently been added.

Greetings,
Marcus

Hi

I have written a block in python and was trying to create an out of tree module as given in the gnuradio tutorial. 
While using cmake ../ the following error occured. 
CMake Error: CMake can not determine linker language for target:gnuradio-dec
CMake Error: Cannot determine link language for target "gnuradio-dec".

this was rectified by removing the lib directory and the cmake file was created without error. Then i run the make install and found following error: 

Scanning dependencies of target _dec_swig
[ 46%] Building CXX object swig/CMakeFiles/_dec_swig.dir/dec_swigPYTHON_wrap.cxx.o
Linking CXX shared module _dec_swig.so
/usr/bin/ld: cannot find -lgnuradio-dec
collect2: error: ld returned 1 exit status
make[2]: *** [swig/_dec_swig.so] Error 1
make[1]: *** [swig/CMakeFiles/_dec_swig.dir/all] Error 2
make: *** [all] Error 2

what should i do to rectify this linking  error.. 


Regards
