slackrepo oddity

Richard Cranium · 04-05-2019, 11:55 PM

In any most (see below) slackrepo (wonderful tool, BTW!) build that pulls in graphviz on my Slackware64 14.2 build box, I get the following...

Code:

graphviz-2.40.1-x86_64-3_SBo: Graph Visualization ...................... [18M] 
Warning: Could not load "/usr/lib64/graphviz/libgvplugin_gd.so.6" - file not found

When I look in the overlay, I see those libraries...

I'm rather puzzled by these warnings.

TBH, I'm not sure why

Code:

chroot . /usr/bin/dot -c

in doinst.sh is superior to

Code:

( cd / ; /usr/bin/dot -c )

EDIT: Now that I'm watching, the libinput and QT5 builds did not show the above behavior.

I, to was excited by the potential of slackrepo, and saddened by the lack of performance. As for these,

It's a question of perspective. The chroot allows you to doctor up some special conditions to operate that software only on, whereas the 'cd /' approach uses the main system.

Code:

this sets your current dirctory as a virtual root directory
chroot . 
this changes your current directory to the top of the filling system
cd /

Ah, the issue is that installpkg et al allows you to set the install root (which makes sense for the initial installation of Slackware). chroot . will DTRT in that case, whereas ( cd / ; blah ) will not.
