You're the first person that I've heard of who is trying this on Windows, so you're breaking new ground here!

I don't think I've done anything in the code that won't work on windows, but I rarely use windows, so it's hard to say for sure.

The error you're getting suggests that either the libcec library isn't installed, or the compiler can't find the right headers for it. I don't really know how development on Windows works, so the best advice I can give it to make sure that you've installed the libcec library from pulse-eight and that your compiler can find the headers and the dll for it.

I am also trying this on Windows. Turns out, the code written in cec.cpp has issues with Windows (min/max stuff).

Though, after figuring out what caused that, I was able to get it to compile a little further. Now, it gets stuck on: LINK : fatal error LNK1181: cannot open input file 'cec.lib'

I'm not entirely sure what this means. There's no cec.lib anywhere, nor is one being generated.

nforro commented 5 years ago

cec.lib is the object file that is being compiled from cec.cpp, so my guess is you still have some compilation errors that you may have missed.

Could you share the complete output?

nforro commented 5 years ago

@Valkhan You have to build or install libCEC and provide proper include path to compiler and proper libpath to linker.

Valkhan commented 5 years ago

@nforro is there a Guide in this repo or elsewhere that I could follow?

nforro commented 5 years ago

Assuming libCEC is installed in C:\libCEC (cec.dll and libcec.dll are in that directory), the following in setup.py should work:

python_cec = Extension('cec', sources = [ 'cec.cpp', 'device.cpp' ], 
                        include_dirs = [ 'C:/libCEC/include' ],
                        library_dirs = [ 'C:/libCEC' ],
                        libraries = [ 'cec' ])

I'm only guessing here, since I have no way to test this.

Step by step instructions would be the following:

If it works, we can think about how to adjust setup.py to make it work out of the box.

Valkhan commented 5 years ago

Thank you for the quick response, I'll try it later today and get back to you with the results, I already have libcec installed.

"If it works, we can think about how to adjust setup.py to make it work out of the box."

That would be awesome!

Valkhan commented 5 years ago

@nforro So here's my test results

I did as recommended, installed libcec on c:\libcec and all other dependencies

Downloaded the master branch.

My hardware is:

Got invalid token and some syntax error.

If it helps the source language is Portuguese, cpp isn't my strong language, from here on I don't have many experience.

Can you help me once again? do you have any insight on a possible solution?

I'll also want to add, that this guidelines on installation as well as some of my steps could be added to readme

nforro commented 5 years ago

Pay attention to arguments passed to cl.exe (the compiler). -I sets additional include paths.

You can see "-IC:\Program Files (x86)\Pulse-Eight\USB-CEC Adapter\include" in the first run, which seems kind of right, as C:\Program Files (x86)\Pulse-Eight\USB-CEC Adapter is the default installation path for libCEC, but clearly it is not, as the headers are not there. I have no clue where it comes from. Apparently, one can set INCLUDE environment variable and the compiler will take it into account, and libCEC installer seems to be doing that. Which means no modification of setup.py should be needed.

In the second run you can see -IC:\libcec\include, which is correct. However, I didn't realize there is no libcec subdirectory in C:\libcec\include, so either create it and move the header files into it, or remove the libcec part from the #include directives.

I'll also want to add, that this guidelines on installation as well as some of my steps could be added to readme

Ideally we should make necessary adjustments so that no guidelines are needed.

Valkhan commented 5 years ago

@nforro I'll try your suggestions, thank you again for your time.

Valkhan commented 5 years ago

@nforro thank you for all of your support and time, but I couldn't get it to work, I'll stick to linux for the time being the device i'm working on will be returned to the owner this night and i'll be unable to procced with tests.

If the owners of this discussion doesn't have anything to add this issue may be closed by my understanting.
