Well does the multiarch feature of 11.10 mean 64bit users will be able to install 32bit '.debs' without resorting to the 'force--architecture' command?
There is indeed no need for
--force-architecture anymore with multi-arch support with a some notes:
- The libraries on which the package depend must support Multi-arch
- Even if multi-arch is supported, it's possible for a library package to make the system install either the 32-bit version or the 64-bit one, but not both. So, the package in question should not have a need to depend on such a library unless there is no 64-bit equivalent necessary.
Many packages from third-party websites do not set the necessary dependencies. Before multi-arch, a dirty hack called
ia32-libswas created. This would contain the 32-bit libraries for multiple packages, and therefore it was easy for the maintainer to say "just install the
ia32-libspackage." In most cases, the dependencies are mentioned for the 32-bit sysems, so you should install those, but for the 32-bit architecture by adding
:i386after each package as in:
sudo apt-get install libgl1-mesa-glx:i386 libc6:i386
