When trying to build indicator-datetime I get the following error:

This is indicator-datetime from trunk on Gentoo Linux with both evolution-data-server 3.2.3 and 3.4.3. Full build log attached.

It builds fine on Ubuntu Quantal, so shouldn't this bug be filed against indicator-datetime on Gentoo? Or against evolution-data-server on Gentoo?

Seems like Gentoo places the header files for libecal at a different location.

[Pim Vullers (pimvullers)]

Reported it at Gentoo bug tracker: https://bugs.gentoo.org/show_bug.cgi?id=427826

I am trying to package indicator-datetime for Gentoo, it seems the files are non-existent, so reported it as a evolution-data-server bug.

Gentoo gnome team member here.

libecal/libecal.h is only available in evolution-data-server-3.5.3 and higher. If you cannot avoid using that header, I strongly recommend you to put

ECAL_REQUIRED_VERSION=3.5.3

in configure.ac so that gnome-3.4 and 3.2 users will be easily able to tell why the build failed -- and so that packagers will be able to set the correct lower bounds on your application's build dependencies :)

[Pim Vullers (pimvullers)]

Bilal, could you please report the version of evolution-data-server in Ubuntu, and whether you know of any back-ported patches?

Alexandre, thanks for your very helpful response. I'll include a newer version in the elementary overlay (or one with back-ported patches from Ubuntu) to fix these build issues (or take it from gnome overlay, when available).
