On FreeBSD, ImageMagick6 and ImageMagick7 packages cannot be installed at the same time as they have several files in common.
It becomes a problem when some packages depend on ImageMagick6 (as inkscape for example) and some others on ImageMagick7 (as emacs for example).
To circumvent this problem, we can "patch" the ImageMagick6 package to delete the files installed by ImageMagick7.
So ImageMagick7 is installed:
$ pkg info ImageMagick\*
ImageMagick7-7.0.10.6
First download the ImageMagick6 package:
$ pkg=$(pkg rquery %q/%n-%v ImageMagick6)
$ fetch https://pkg.freebsd.org/${pkg%%/*}/latest/All/${pkg#*/}.txz
Then download the "package-patcher" script:
$ fetch https://gist.githubusercontent.com/maxatome/dcd48de511f087c10f02a59405f134b6/raw/9e9843d87dace00e506ea848c69cf29ad09dbf6a/patch-ImageMagick6.pl
Do not forget to look at its content before executing it!
- L27 it creates a temporary directory that it automatically cleaned up at end;
- L29-31 it extracts the package it it
-
L33-34 it reads the
+MANIFESTto get the list of package files; -
L36-57 it deletes unneeded files from
+MANIFESTand from disk -
L59-63 it rewrites the
+MANIFEST -
L65-75 it creates a new package adding
-libonlyto the original package name.
Then (no need to be root at this step), patch the package:
$ perl patch-ImageMagick6.pl ${pkg#*/}.txz

Just install the produced package using pkg install as root:

Extracting ImageMagick6-6.9.11.6,1: 100%
inkscape package can now be installed without any conflict with emacs, as both versions of ImageMagick are installed:
> pkg info ImageMagick\*
ImageMagick6-6.9.11.6,1
ImageMagick7-7.0.10.6
It is a good idea to lock the ImageMagick6 package to avoid that the next pkg upgrade raise a conflict:
# pkg lock ImageMagick6-6.9.11.6,1
ImageMagick6-6.9.11.6,1: lock this package? [y/N]: y
Locking ImageMagick6-6.9.11.6,1
