Dear Sir,

I have comment out the "#include <complex.h>", but still has error, as below:

Please advise, thanks.

In your previous pull request, you deleted the line:

#include <complex.h>

in gr-dtv/lib/dvbt2/dvbt2_paprtr_cc_impl.cc

This would directly fix the build issues reported by Activecat and Marcus Leech.

I'm not sure my forthcoming pull request directly addresses these specific issues, but it does a bunch of others for C++11 compliance in std::complex -- whether or not you're using C++11; it's backward compatible with C++0x and earlier, and should be forward compatible as well. Before we address these specific issues, let's get my patches in place -- they remove all of the GCC extensions to std::complex, so they might have an impact on these issues. I should be able to do the PR tomorrow; still testing on various systems tonight. - MLD

I believe Michael Dickens will have a comprehensive fix for issues like this soon.
