[Bug 1306629] Re: [SRU] SDL_syswm.h can't find mir_toolkit/mir_client_library.h

[Benjamin Xiao]

Thanks I'll try the workaround.

It does make sense for them to include Mir support though even if it's
not released yet. Developers have to do testing on Mir and Mir is still
an installable option on Ubuntu 14.04. SDL, along with many other
programs, have support for various things compiled in. Not all of them
are used, but they are supported and therefore have to be inside the
compiled code.

Title:
  [SRU] SDL_syswm.h can't find mir_toolkit/mir_client_library.h

Status in Mir:
  Invalid
Status in “libsdl2” package in Ubuntu:
  In Progress

Bug description:
  I believe something is wrong with MIR support. A daily build of openmw
  just failed with:

  /usr/include/SDL2/SDL_syswm.h:97:44: fatal error: mir_toolkit/mir_client_library.h: No such file or directory
   #include <mir_toolkit/mir_client_library.h>

  In SDL_syswm.h:
  #if defined(SDL_VIDEO_DRIVER_MIR)
  #include <mir_toolkit/mir_client_library.h>
  #endif

  the file is:
  /usr/include/mirclient/mir_toolkit/mir_client_library.h
  http://packages.ubuntu.com/search?searchon=contents&keywords=mir_client_library.h&mode=exactfilename&suite=trusty&arch=any

  openmw buildlog:
  https://launchpadlibrarian.net/172588668/buildlog_ubuntu-trusty-i386.openmw_0.29%2Bgit20140411.77-0~ubuntu14.04.1_FAILEDTOBUILD.txt.gz

  it built successfully until the fix for bug #1295389 libsdl2 commit
  hit that enabled mir.

  Assigning "high" since it has the potentially to cause a large number
  of FTBFS in the archive.

  
  SRU Info:
  *Note* This patch has landed in libsdl2 upstream:
  https://hg.libsdl.org/SDL/rev/274017846e73

  1) The issue is sdl2.pc does not include mir_cflags, so the headers are in an unknown location. So when programs compiled against SDL2 with mir enabled, it could not find the mir headers.
  2) A simple way to test the current Mir problem:
  http://paste.ubuntu.com/7271077/
  3) Regression potential: Very low, this is a 1 line patch, that adds the MIR_CFLAGS to the SDL_CFLAGS.
