Installing the libs from IM-6 alongside IM-7.
Posted: 2017-01-11T19:06:36-07:00
For my personal use, I think that ImageMagick-7 is great. And some of the other packages I install which can use ImageMagick work fine with -7. But the major changes between 6 and 7 mean that not everything has caught up.
In BLFS we are aware of two packages which only recognise IM-6 : emacs-25.1 (not something I use, but some people like it) and inkscape (which I do minimally use). For those, I have produced a patch (currently tested with 6.9.6-8) using our instructions - it changes the unversioned pkgconfig files to have -6.pc names, and adds an install-libs-only target (no programs, no manpages). It assumes anyone doing this will NOT build the perl part for 6 : use 7, it's better
and it is only tested with my own HDRI builds.
But it does mean I can install 7 in a normal build, and then later install the libs and headers from a patched version of 6 (we use direct installs).
The patch is athttp://www.linuxfromscratch.org/patches ... ly-1.patch and the current build instructions for 6 are at http://www.linuxfromscratch.org/blfs/vi ... gick6.html (with the full instructions for 7 on the next page).
Unfortunately, the unversioned pkgconfig files are now for -7 so packages will look at them, decide they don't fit, and reject them. For emacs (and I guess any other programs using a configure script), adding
But inkscape has now moved to using cmake. For that there is a patch at
But seriously - we usually find things in other distros, but most of the big players are still using 6. I hope somebody may find this useful.
