Below is my message:

Package: libc6
Priority: required
Section: libs
Installed-Size: 9336
Maintainer: Ubuntu Core developers <ubuntu-devel-discuss at lists.ubuntu.com>
Original-Maintainer: GNU Libc Maintainers <debian-glibc at lists.debian.org>
Architecture: i386
Source: eglibc
Version: 2.10.1-0ubuntu18
Replaces: belocs-locales-bin
Provides: glibc-2.10-1

But when I try to configure lttv
it shows the error below, should I miss any setting, such path, in my ubuntu?

checking for GLIB - version >= 2.4.0... no
*** Could not run GLIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.
configure: error: glib is required in order to compile
LinuxTraceToolkit - download it from ftp://ftp.gtk.org/pub/gtk

appreciate your help,
