Public bug reported: There is a package dependency problem for Scilab and pkg-config.
$ sudo apt-get install scilab -qq then $ pkg-config scilab --cflags-only-I Package libxml-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `libxml-2.0.pc' to the PKG_CONFIG_PATH environment variable Package 'libxml-2.0', required by 'libscilab', not found The libxml2-dev package contains the 'libxml-2.0.pc' file mentioned in the error message. Installing the appropriate package fixes the problem: $ sudo apt-get install libxml2-dev -qq $ pkg-config scilab --cflags-only-I -I/usr/include/libxml2 -I/usr/include/scilab More info about scilab: $ apt-cache policy scilab scilab: Installed: 5.5.0-2 Candidate: 5.5.0-2 Version table: *** 5.5.0-2 0 500 http://gb.archive.ubuntu.com/ubuntu/ trusty/universe i386 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: pkg-config 0.26-1ubuntu4 ProcVersionSignature: Ubuntu 3.13.0-34.60-generic 3.13.11.4 Uname: Linux 3.13.0-34-generic i686 ApportVersion: 2.14.1-0ubuntu3.3 Architecture: i386 CurrentDesktop: Unity Date: Tue Sep 2 07:53:28 2014 InstallationDate: Installed on 2014-08-16 (16 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release i386 (20140722.2) SourcePackage: pkg-config UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: pkg-config (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1364242 Title: Package dependency problem with scilab and pkg-config To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pkg-config/+bug/1364242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
