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 \ is undefined in . I’ll have a fix for this soon. Ron ---

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 \ in gr-dtv/lib/dvbt2/dvbt2\_paprtr\_cc\_impl.cc This would directly fix the build issues reported by Activecat and Marcus L… Ron ---

The actual fix is a little more complicated. You can download a patched file from here: [http://www.w6rz.net/dvbt2\_paprtr\_cc\_impl.cc](http://www.w6rz.net/dvbt2_paprtr_cc_impl.cc) [w6rz.net](http://w6rz.net) is my personal website. Ron ---
