Dear Sir,
Recently I failed to install GNU Radio using PyBOMBS.
Error message:

I am using Debian 7.8 64bit.

Please advise me how to solve this installation error.
Thank you very much.
I know what’s causing this error. It’s a function of using the GCC 4.7
compiler. It works with GCC 4.8 or later because the define “complex” in
<complex.h> is undefined in .
I’ll have a fix for this soon.

I believe Michael D. will have a comprehensive fix for issues like
this soon.
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
Ok; my PR will remove that header, so hopefully it’ll take care of the
issue. - MLD
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 L…

Ah, this probably explains my failure earlier today for apparently the
same reason.
Dear Sir,
I have comment out the “#include <complex.h>”, but still has error, as

Please advise, thanks.
The actual fix is a little more complicated. You can download a patched
file from here:
