Making a package multiarch (for real)
[CC me please]
I am trying to make CharLS a true multiarch capable package. However I
fail to understand what I did wrong.
Steps:
$ apt-get source charls
$ cd charls-1.0
$ vim debian/control
-> mark libcharls-dev as `Multi-Arch: foreign` and libcharls1 as
`Multi-Arch: same`
Build on both amd64 and i386:
$ dpkg -I libcharls1_1.0-5_amd64.deb | grep same
Multi-Arch: same
$ dpkg -I libcharls1_1.0-5_i386.deb | grep same
Multi-Arch: same
shared lib are using proper multiarch paths:
$ dpkg -c libcharls1_1.0-5_amd64.deb

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libcharls1:i386 : Conflicts: libcharls1 but 1.0-5 is installed
E: Unmet dependencies. Try using -f.
How do I get a detailed diagnosis of the conflicting files ?
