Error compiling: opencv.pc file not found. #1294

Open maq33 opened 2 years ago

maq33 commented 2 years ago

I tried to compile the v6 branch inside a container using Debian stable and I got the following error:

root@localhost:/opt/meguca# make
go build -v
# github.com/mattn/go-sqlite3
sqlite3-binding.c: In function ‘sqlite3SelectNew’:

# pkg-config --cflags  -- opencv
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
pkg-config: exit status 1
make: *** [Makefile:30: server] Error 2

I searched for this file "opencv.pc" in Debian repositories:

https://packages.debian.org/search?searchon=contents&keywords=opencv.pc&mode=exactfilename&suite=stable&arch=any

This file is not found in the stable version of this package, but is found in oldstable:

https://packages.debian.org/search?searchon=contents&keywords=opencv.pc&mode=path&suite=oldstable&arch=any

This should be fixed.

This is a known issue. v6 currently does not compile on Debian stable. It is recommended to use the docker container as an alternative.
