Hi ,
Sorry for not providing all the info . I dont know what happened to the
link though .
I used gr_modtool to create the OOT module ;
I wrote the module in C++ and i am using GNU Radio 3.7.6
I have created a git repository :
https://github.com/Jadoobaba/gr-wsi/tree/master/Documents/gr-wsi
ldd on the .so file has the following output .
