Comment on attachment 649736 [details] build.log Why did you store a single file in a tar archive? Did you know you can just as well compress files directly, without using tar?
I don't understand what's wrong with: tar -zcvf build.log.tgz /tmp/portage/media-libs/opencv-4.1.2-r3/temp/build.log I have been compressing like this for about 20 years.
Please re-open if this is reproduced with 4.6.0.
