I have problems in the compilation in cmake I fulfill all the requirements
What is your GCC version? You can find out with:
gcc -v
According to what I just read here, the support for the C++11 feature used here was only added for gcc version 4.8 (support for inheriting constructors). If you wait till after the weekend (I will be away) I can probably strip usage of this feature away, or you can try updating your compiler. I'd prefer to not use such a bleeding edge feature if it is going to cause problems, so I'd like to try to clean it up and fix it for you.
Greetings, thanks for answering me, I think the gcc version I have is version 4.7.
I will update the compiler to version 4.8 Thank you

@retrocant alternatively, you can also use clang, whenever gcc fails for you. But I agree on the point, that we need to have some "cutoff", where we consider features as "bleeding edge" and not use them.
Maybe we could use out-of-the-box Ubuntu 16.04.x LTS as a standard, where we expect our driver to compile. We could remove "bleeding edge" C++11 features, until it compiles on that platform.
Greetings, I just compiled perfectly updating the gcc to the last version and it worked perfectly in the compilation, now I have a problem and it is that I do not get to work and it can be by the controllers and of course in the privileges. I can not open the gchd.ts file in /tmp/gchd.ts probably due to permissions. And if I get to open the fcihero in videolan it comes out in black and I do not see the video capture on screen. The version that I have of the cat is the HD and supposedly is compatible, the driver files are located in their respective carpets that you comment. any ideas?

For testing purposes, I would recommend using sudo gchd, in order to create the /tmp/gchd.ts file. Set permissions to 777 using sudo chmod 777 /tmp/gchd.ts and try to open the file in VLC. Watch your terminal for any output.
Due to some instability in the latest code, I would recommend replugging your Elgato, before you start a new attempt with sudo gchd. The device reset is not working 100% reliably for GCHD1 device as of now. Alternatively, if you have a GCHD1 (PID 0x0044, 0x004e and 0x0051, you can look it up by using lsusb), you can use release 0.2.0 which is working reliably, minus all the auto-detection and GCHD2 support.
Greetings I send you captures as I have everything structured, still not working.[image: Imágenes integradas 1] [image: Imágenes integradas 2] [image: Imágenes integradas 3] [image: Imágenes integradas 4]

Just want to ask what device you are capturing from. Thinking you may have hdcp copy protect issues possibly. Will look at captures properly when back home.
