I think you miss my point. I know how to install linux-c7-libpng. My
concern is why this whole set of ports was not already installed.
Sorry to have been unclear. I meant to suggest that linux-c7-libpng was
already "installed" i.e. registered as such, but that its files were
missing due to some other problem.
I kept adding one port after another, but I have no idea where that
ends. The ports system should install all dependencies automatically.
Since only a single linux emulation port is a dependency, I guessed
that linux-c7-gtk2 is the culprit, bu reinstalling it generated that
odd message:
Installing linux-c7-gtk2-2.24.31...
/compat/linux/usr/bin/gtk-query-immodules-2.0-32: error while loading
shared libraries: libpng15.so.15: cannot open shared object file: No such
file or directory
Looking at linux-c7-gtk2, I see "USE_LINUX= atk gdkpixbuf2 pango
xorglibs". I have already re-installed atk and pango, but the others
are not installed. Since pkg shows that these are not installed, I
would have expected that building linux-c7-gtk2 to have installed
them. /usr/ports/Mk/Uses/linux.mk <http://linux.mk> states "#
USE_LINUX List of Linux packages to depend on." So I am baffled as
to why these ports are not being installed. (I have tried both
portmaster(8) and a simple make(1).) Clearly something is broken here
and it looks a lot like the ports system, mabey linux.mk
<http://linux.mk>.
Deleting /compat/linux/usr/lib/libpng15.so.15* (but leaving
linux-c7-libpng "installed", although damaged) and then installing
linux-c7-gtk2 seems to reproduce the behavior you are seeing. If I
remove linux-c7-libpng completely, by 'pkg remove' or 'make deinstall',
then a 'make install' for linux-c7-gtk2 installs the libpng as expected.
On your system, is the Linux libpng port not installed at all, or is
there some possibility the installation is damaged?
The linux gtk2 has a USE_LINUX for gdkpixbuf2, which in turn has a
USE_LINUX for png. While ideally installing a port would check for all
needed files, this doesn't seem to work, at least for the Linux ports.
