Make failing for new gnuRadio install on ubuntu for interpolating_resampler.cc

[Sandeep-Sarma]

On checking out the latest version (commit: bd61122), I get the following errors on make:

make[2]: *** [gr-digital/lib/CMakeFiles/gnuradio-digital.dir/interpolating_resampler.cc.o] Error 1

What is your OS version?

This compiles on Fedora 26 and for the git PR buildbot without error. The problem appears to be the version of C++ in use is being very particular about wanting a real pointer value and not NULL, which is just an integer. The simple solution is to remove the 2nd argument (NULL) in the 8 vector initializer calls in that file.

Thanks. Let me try that. My OS version is Ubuntu 12.04.

[jmcorgan]

I'm going to be pushing a PR for fixing this that should work for you, but please remember that Ubuntu 12.04 is no longer supported by us or Canonical.

[Sandeep-Sarma]

Thanks Sir. Point noted.

@Sandeep-Sarma PR #1389 has the recommended changes; please confirm this solves your problem as we do not test gcc 4.6 or Ubuntu 12.04.
