[Bug 949606] Re: 64 bit dev packages should include 32 bit .so library file

 

The second workaround does not work with apt-get; e.g.:

The following packages have unmet dependencies:
 libglu1-mesa-dev : Conflicts: libglu1-mesa-dev:i386 but 9.0.0-2 is to be installed
 libglu1-mesa-dev:i386 : Conflicts: libglu1-mesa-dev but 9.0.0-2 is to be installed
E: Unable to correct problems, you have held broken packages.

Title:
  64 bit dev packages should include 32 bit .so library file

Status in mesa package in Ubuntu:
  Triaged

Bug description:
  64 bit dev packages contain a 64 bit version of the library file(s)
  that they provide for linking but not a 32 bit version of the library
  file(s). In previous versions of Ubuntu, however, it was possible to
  compile 32 bit applications using the 64 bit dev packages in by
  installing ia32-libs, which contained the required 32 bit library
  files.

  In the move to multiarch, 32 bit library files are being removed from
  ia32-libs. Multiarch (I assume) aims to keep the architectures
  separate, so the generally intended solution is to install the i386
  version of the dev package when compiling 32 bit applications, ie
  side-by-side with the 64 bit dev package.

  However, some 64 bit development packages conflict with their 32 bit
  equivalent. This creates a regressive situation where it is impossible
  to install them side-by-side - you are forced to either install the 32
  bit package, which breaks 64 bit compilations, or the 64 bit package,
  which breaks 32 bit compilations.

  An example is libglu1-mesa-dev, which conflicts with libglu1-mesa-
  dev:i386. The libglu1-mesa-dev file contains all the necessary
  development files for 32 bit *except* for the 32 bit library file. It
  does contain the 64 bit library file. Since the library file is part
  of the development files, libglu1-mesa-dev does not contain all the
  necessary development files for 32 bit, ie it does not contain all the
  necessary development files for multiarch. I think that it *should*
  contain all the necessary files for building multarch applications.

  The two workarounds are:

  1. Manually re-install the required i386 dev packages before compiling
  32 bit apps, and then manually re-install the required amd64 dev
  packages before compiling 64 bit apps. This is a real pain.

  2. Install the i386 binary package (eg libglu1-mesa:i386) and the
  amd64 dev package (eg libglu1-mesa-dev), and manually create symlinks
  for the i386 libXYZ.so package (eg sudo ln -s /usr/lib/i386-linux-
  gnu/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so). This is a more
  permanent solution but is a real pain to set up, as you have to find
  each missing library manually, and some library files, like
  mesa/libGL.so.1, are in subfolders.
