Warnings in .DEB creation #5

Closed eddiecsilva closed 4 years ago

eddiecsilva commented 4 years ago

Thanks so much for sharing this information, when trying to perform this procedure on Ubuntu 19.10 beta at the end of creating the DEB packages I get a message that 1 error and 7 warnings occurred.

The packages are generated and I can complete the installation without any problems, but I would like to know if these messages can be handled.

How can I check for these errors and warnings?

Those are small errors/anomalies in FFmpeg's man pages and build scripts. Like FFmpeg's C compiler warnings that you see when making, they're not a big problem (sometimes even intentional or a bug in lintian), and when they are a problem, they're only able to be fixed with upstream patches.

Can you just output when these errors are generated in the build process and copy them and post them here. When do they happen - like before entering sudo dpkg -i *.deb or after - normally no errors should occur in the build process, not even of the C dynamic binaries (ffmpeg ffprobe ffplay) nor the shared libraries

@catb0t I think he has the extra* problem. Idk I might be on the completely wrong tracks and it is all about the actual compilation process.

Thank all of you for the informations.

The distributions where I tested the installation process were environment already in production and with a lot of programs installed, I intend to test in a clean installation.

Not sure if this influences, but my GPU is a GTX 1650 4Gb on an AMD Ryzen 5 platform.

You're right, when trying to install the packages I had problems with libavcodec-extra58 and had to remove it manually.

Sorry, I thought you were referring to the errors at the end of debuild, where it says "7 warnings" from lintian.
