Re: [Discuss-gnuradio] Problem linking volk gnuradio3.7.4

[Marcus Müller]

Stefano,

you sent the same mail *four* times, which is not really increasing the
likelihood of it being answered. Please have a little patience; it's
weekend, and many of the experts reading this mailing list are enjoying
that :)

Anyway, this is a linker error, and it's a little hard to guess what
goes wrong. Just a few hints:
- Make sure there is only one version of boost installed on your system,
and that the version of boost headers in /usr/include match the version
of the library installed to /usr/lib
- If you're using the same build folder as for 3.7.3, try make clean &&
make (Protip: install ccache / ccache-swig first!), and if that doesn't
help, rm -r build && mkdir build && cd build && cmake .. && make

Basically, what goes wrong is that your compiler thinks it can use a
function from the boost library, but your linker doesn't find it, which
usually doesn't happen.

Greetings,
Marcus
