cannot install package

[guydotan]

Not sure if this is an issue with R 4.0.0 but i cannot install this package anymore. This is preventing ggimage package from working...

You need to install pkgconfig. What is your OS?

[guydotan]

I am running OSX. Just tried installing pkgconfig, does not seem to help.

However, I was able to get the package to work (as well as gg_image) when responding No to:
Do you want to install from sources the package which needs compilation? (Yes/no/cancel)

Hi @jeroen,
I'm on Ubuntu 18.04 and run into the same problem (R version 3.6.3).

Package librsvg-2.0 was not found in the pkg-config search path.

But it's there?: /usr/lib/x86_64-linux-gnu/pkgconfig/librsvg-2.0.pc
Also:
echo $PKG_CONFIG_PATH results in
/usr/lib/x86_64-linux-gnu/pkgconfig

The rest of the error message:

Perhaps you should add the directory containing `librsvg-2.0.pc' to the PKG_CONFIG_PATH environment variable
No package 'librsvg-2.0' found
Using PKG_CFLAGS=
Using PKG_LIBS=-lrsvg
...
<stdin>:1:26: fatal error: librsvg/rsvg.h: No such file or directory
compilation terminated.
--------------------------------------------------------------------
ERROR: configuration failed for package ‘rsvg’

Could you please point me towards the solution?

Best,
David

[jeroen]

It could be that some dependency is missing. What do you see if you run in the shell: pkg-config --libs librsvg-2.0 ?

It should not be needed to set PKG_CONFIG_PATH if you installed librsvg using apt-get. In fact it is better to not set it.

[yesdavid]

thanks for your reply! when I run the command this appears:

Package librsvg-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `librsvg-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'librsvg-2.0' found

I tried sudo apt-get install librsvg2-bin and the same for librsvg2-dev. Both are already at the newest version.

[jeroen]

That is strange, do you have any environment variables set that affect the result? Try with

unset PKG_CONFIG_LIBDIR
unset PKG_CONFIG_PATH
pkg-config --libs librsvg-2.0

[yesdavid]

Thank you for your swfit reply, @jeroen!
I executed your commands. When running pkg-config --libs librsvg-2.0 I get this result:

Package librsvg-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `librsvg-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'librsvg-2.0' found

However, librsvg2-dev is already the newest version (2.40.20-2ubuntu0.2). (Or which library do I have to install?)

I am not aware of any changed environment variables.

[jeroen]

I don't understand, I just tested this on ubuntu 18.04 and it works for me. There must be something wrong with your config.

Can you show the output for:

which pkg-config

pkg-config --variable pc_path pkg-config

env | grep PKG_CONFIG

pkg-config --list-all

[yesdavid]

• which pkg-config:
  -- /home/linuxbrew/.linuxbrew/bin/pkg-config - aha! that might be the reason? I had to install that the other day

• pkg-config --variable pc_path pkg-config:
  -- /home/linuxbrew/.linuxbrew/lib/pkgconfig:/home/linuxbrew/.linuxbrew/share/pkgconfig:/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/os/linux/pkgconfig

• env | grep PKG_CONFIG:
  -- nothing

[jeroen]

Yes that is the reason, if you remove linuxbrew from your PATH it will work.

[yesdavid]

thank you very much! I know this is not directly related to this issue, but what would I have to do to install it regularly and not inside brew?
