Missing Dependency in description.

[ralmond]

I was trying to install ragg under R 4.2.1 and Pop_OS 22.04 (Pop_OS is downstream from Ubuntu and Debian).

I'm getting the following error:

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

The information in the suggestions after ANTI-CONF is not quite correct. libfreetype6-dev should be libfreetype-dev.

When I install that library, it compiles without error.

@jeroen do you know anything of the difference between the libfreetype and libfreetype6 packages?

Pretty sure it generally work with libfreetype6-dev so don't know why it doesn't for you

I don't know libfreetype6-dev wasn't working. It might be that I had the amd64 version installed and I also needed the i386 version.

I suspect that the version without the number is an alias for the current version (which is currently 6)

Hey, I received some of those errors. chatgpt assisted me, and it said i need to install libtiff in my PKG_CONFIG_PATH.
it suggests brew install libtiff. It looks like there is a file in brew called "pkg-config", and I assumed this is analogous to PKG_CONFIG_PATH.
first install libtiff in terminal: brew install libtiff
So once you install libtiff, you need to copy it: cp -r /opt/homebrew/opt/libtiff /opt/homebrew/opt/pkg-config
I had to do this as well for freetype. Once i did that, those error messages cleared up. However, i think i am having an intel vs apple silicon based processor issue now.
