Re: [Discuss-gnuradio] Adding Static Library Links with Custom GNU radio blocks

[alfayez]

Sorry I forgot to include some relevant info.  After setting the following variables in the Makefile.am, the make check stage in the python folder is failing with an undefined symbol error "square" basically it's not seeing the square function in the "libcalc_square.a" library

howto_la_swig_libadd =        \
    -lcalc_square

howto_la_swig_ldflags =    \
    -L/home/alfayez/workspace/gnuradio_custom_blocks/gr-howto-write-a-block-3.2.2/src/lib

sorry for the double email question.

Subject: [Discuss-gnuradio] Adding Static Library Links with Custom GNU radio blocks

hi, I am trying to compile the "gr-howto-wtite-a-block-3.2.2" and link an external static library to it.  I've enabled "howto_la_swig_ldflags" and added the directory to the static library in it and enabled the "howto_la_swig_libadd" and added the static library name to it.  While observing the output of the make process I can see that the parameters are being detected and I get a warning message saying that linking the static library to the shared library is not portable which makes sense.

to make sure that I am doing the linking properly, I'm starting out by making a static library that sqaures a number, basically reimplementing the tutorial using a static library function call instead of regular C-code.  I know that using a static library might not be the best choice but for what I'm doing I have to be linking to a static library.  Thanks people.
