Automatic LIB_DEPENDS detection?

AntumDeluge · Jan 23, 2015

I created a new port of the software MediInfo GUI, which depends on x11-toolkits/wxgtk30. I did not add the requisite libraries to LIB_DEPENDS in the Makefile, but after installing and running pkg info mediainfo-gui it lists the wx libs as dependencies:

Code:

$ pkg info mediainfo-gui
mediainfo-gui-0.7.72

MediaInfo is a convenient unified display of the most relevant technical and
tag data for video and audio files.

Does that mean the the dependencies were automatically detected and I do not need to add them to LIB_DEPENDS?

Here is the Makefile (mostly copied from multimedia/mediainfo):

You can create similar list of required libraries with ldd() - maybe this list is generated with ldd too. It can be run when the binary is ready (after build).
It's a helpful utility to add all library dependencies to your Makefile.

I think output of pkg info --dependencies mediainfo-gui doesn't contain x11-toolkits/wxgtk30 - only if you specify explicitly in Makefile.
