[Micha Lenk (micha)]

Just tried it on my own with libgwenhywfar 4.1.0-1: fails to build (confirmed)
and with libgwenhywfar 4.2.1-1 from Debian: fails to build too. :(

[Micha Lenk (micha)]

The build already fails at configure stage:

checking if QT4 is allowed... yes
checking for qt4 includes... -I/usr/include/qt4 -I/usr/include/qt4/Qt -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui
checking for qt4 libraries... not found
checking for qt4 moc... /usr/bin/moc-qt4
checking for qt4 uic... /usr/bin/uic-qt4
configure: WARNING:
 QT4 is not explicitly disabled and I could not find some QT4 components
 (see which are missing in messages above).
 If you don't want to compile QT4 applications please use "--disable-qt4".

[Micha Lenk (micha)]

Adding --with-qt4-libs=/usr/lib/i386-linux-gnu to the configure flags fixes the build for i386, so it seems an issue caused by missing support for multi-arch by the Gwenhywfar build system.

[Micha Lenk (micha)]

The attached patch should fix the build failure.

The patch cannot be uploaded to Debian yet, because on Debian systems the Qt libraries still live in /usr/lib (the single arch path), and the additional flag causes the build system to look in the specified directory only.

A better fix (auto Qt path discovery for both, single arch and Multiarch) is already committed to the upstream SVN, so the next upstream version will not need this patch.

[Launchpad Janitor (janitor)]

This bug was fixed in the package libgwenhywfar - 4.1.0-1ubuntu1

---------------
libgwenhywfar (4.1.0-1ubuntu1) oneiric; urgency=low

  * Explicitly configure for qt multiarch location (Micha Lenk). LP: #831205.
