meson error: Native dependency mtdev' not found / pkg-config problem?

  • 772

I'm trying to compile libinput from source using the following script:

$> git clone https://gitlab.freedesktop.org/libinput/libinput
$> cd libinput
$> meson --prefix=/usr builddir/
$> ninja -C builddir/
$> sudo ninja -C builddir/ install

At the third line I get the following error, involving mtdev. I have mtdev-tools installed. 

$ meson --prefix=/usr builddir/

meson.build:117:0: ERROR: Native dependency 'mtdev' not found

Meson uses pkg-config, which doesn't report mtdev. 

$ pkg-config --list-all | grep mtdev
(No results)

I'm not sure if this is the problem, but I don't know how to get pkg-config to "see" mtdev, and I have no idea what else to do.

System: Ubuntu 18.04 LTS. I'm OK with upgrading to 19.04 if that would help.

    You need to install the libmtdev-dev package:

    $> sudo apt-get install libmtdev-dev

    Meson and pkg-config are typically looking for the development files of libraries and systems (the header files *.h and the development libraries lib*.so and lib*.a).

    In Ubuntu (and Debian, and distros derived from these two), development files are typically stored in packages with the -dev suffix. So you usually want to search for those packages when fixing build dependencies on Ubuntu.
