Trouble installing 'rsvg' getting unix pkg-config error.

Problem:

The pkg-congif on my unix server can not find librsvg-2.0 in the pkg-config search path

Debug process

I tried to get rsvg installed and I got the error posted at the bottom.
I know librsvg is installed since I reinstalled it and it said the latest version was installed using:

sudo apt-get install librsvg2-bin

I think Ithe next step is to set the pkg-config to see the new install.

How do I do this?

I have the package installed on a separate nonproject server and I get this result

pkg-config --cflags librsvg-2.0
-pthread -I/usr/include/librsvg-2.0 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/uuid -I/usr/include/freetype2 -I/usr/include/libpng16

on the problem server I get


pkg-config --cflags librsvg-2.0Package 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`

What operating system are you using on your server? Why do you install librsvg2-bin instead of librsvg2-dev as indicated in the error message?

yeah that was it. I did

sudo apt-get install -y librsvg2-dev

and that fixed it. The configuration file is now found. I think I just copied a similar answer I found, but it used package-bin and I didn't realize the difference till you pointed it out. Sometimes you just need a second set of eyes.
Thanks!
