I'm trying to cross-compile glib for gstreamer but encountered the following error in Ubuntu 16.04 terminal:

checking for LIBMOUNT... no
checking libmount/libmount.h usability... no
checking libmount/libmount.h presence... no
checking for libmount/libmount.h... no
configure: error: *** Could not find libmount

Greatly appreciate any advice from the community.


I would've preferred to add this as a comment, but unless you actually need libmount for something it's much easier to simply disable it by passing --enable-libmount=no to configure.

you need the library with headers ... package names ending in -dev contain headers

apt-get install libmount-dev

this will give you the missing headers ... to verify issue

dpkg -L libmount-dev

#  ... output

You need to cross-compile libmount and make it available to the cross-compiler (and presumably cross-pkg-config).

  • so basically i'd need to cross-compile every dependencies to fit my embedded target architecture right? that said i'm not able to find libmount package to cross-compile. do you've any recommended link to download the libmount source? – rainfrost Dec 1 '16 at 1:49

    Yes, you need to cross-compile every dependency (or use a toolchain which includes them, if such a thing exists for your target). libmount is part of util-linux. – Stephen Kitt Dec 1 '16 at 5:09
  • just another question, if I install e.g. apt-get install libmount, it only installs the sources, when i'm cross-compiling, does the cross-compiler knows to grab the libmount source and cross-compile for my target? – rainfrost Dec 1 '16 at 6:33
  • @emddev sorry, I didn't see a notification for your further question. apt-get install doesn't install sources, and the cross-compiler doesn't know to grab the source and cross-compile automatically; you need to explicitly cross-compile all the required libraries. If your target matches an Ubuntu architecture, you could use multi-arch instead. (apt-get source will download the source code, but it won't install it in a pre-defined location, it just extracts it in the current directory.) – Stephen Kitt Feb 25 '17 at 11:02
