I am sorry that I been posting little binaries my self. Not seen fegol files either. Still using my verr BAD Mechanic Hat.
"how do I use this, or how do I transfer this to my box?? just by copy pasting it???"
My experience is that unless new tvheadend modify a new thing in the web info, what I do is just replace the binary file "tvheadend". Just like in oscam. This is the easy way to test. Once we know it is what we need then I remove all package and reinstall a new one as a full package..
As for toolchain I am going some test to try to ensure less error while compiling. See problem is that your developer have made a little Frankenstein. It has part from various different sources. Just give me time to test and I will offer a nice solution. I had build using different toolchain. Some show somw issue other anther one,
fegol You could also post your build way.
