Ubuntu - installation fails with "No package freetype2 found"

[foo-jin]

Ubuntu 16.04, with all the dependencies listed in the README installed. The full error is

--- stderr
configure: error: Package requirements (freetype2) were not met:

No package 'freetype2' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables FREETYPE_CFLAGS
and FREETYPE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Have you tried rebooting after installing the freetype2 dependency? Also make sure the package was actually installed successfully.

[foo-jin]

Yes, all the dependencies installed succesfully (the freetype package listed for ubuntu was libfreetype6-dev instead of freetype2, although that shouldn't matter). Unfortunately I still ran into the same error after restarting.

Edit: the package was called libfreetype6-dev -- typo in comment, not the source of the problem

[chrisduerr]

It should be libfreetype6-dev.

[foo-jin]

You're correct, I made a mistake in my comment. That is the package I had installed however, so that is not the source of this problem.

Manually exporting PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig solved it in my case.
