`magick` is not installed with the library

[tbrown122387]

For some reason my devtools::install_github() fails. I get this

Installing package into ‘/home/taylor/R/x86_64-pc-linux-gnu-library/4.1’
(as ‘lib’ is unspecified)
ERROR: dependency ‘magick’ is not available for package ‘mmrefpoints’

magick is in the DESCRIPTION file, so that's not the problem. It attempted to install magick but I got this:

Perhaps you should add the directory containing `Magick++.pc'
to the PKG_CONFIG_PATH environment variable

If Magick++ is already installed, check that 'pkg-config' is in your

is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

.pc files are DOS-specific if I recall correctly. I'm running this on

Hi @tbrown122387 -- sorry about that.

Have you tried installing the ImageMagick++ library on your machine? For Ubuntu it should be installable using: sudo apt-get install libmagick++-dev (I got this from here).

Secondly, does mmrefpoints load even though you get this error on install? I only ask because in the package, magick is used to run the gif engine for one of the tabs in the app and plays a pretty small role (but one I haven't been able to replace w anything else). If you can still install it, you can review the rest of the package and app's functionality while I figure out the magick issue.

@mcsiple okay great, that works! Maybe a small tidbit should be added to the install section in the README that mentions the added difficulty for Linux folks?

Regarding your second paragraph, I doubt the rest of it would load. I'm looking at the last line of the error message. It just deletes all of the progress if it doesn't get to the end successfully.

Happy holidays by the way!

I added a note to the README for Linux users! Just saw your other message and will answer shortly.
