  • Bug#865429: libc6-dev-i386: gcc-multilib should not be recommended

    From Vincent Lefevre@21:1/5 to All on Wed Jun 21 15:00:01 2017
    XPost: linux.debian.bugs.dist

    Package: libc6-dev-i386
    Version: 2.24-12
    Severity: normal

    The libc6-dev-i386 package has:

    Recommends: gcc-multilib

    But recommended packages are installed by default, and the above
    "Recommends:" is too strong as gcc-multilib is not the only way to
    use libc6-dev-i386.

    The issue is that installing *any* compiler that depends on
    libc6-dev-i386 will have the effect to install the default GCC,
    introducing a potential redundancy.

    An example:

    zira:~> aptitude why gcc-6-multilib
    i gcc-snapshot Depends libc6-dev-i386 (>= 2.11)
    i A libc6-dev-i386 Recommends gcc-multilib
    i A gcc-multilib Depends gcc-6-multilib (>= 6.3.0-9~)

    But that would be also true for gcc-5-multilib, which depends on libc6-dev-i386.

    The "Recommends:" would make sense only if gcc-multilib were a
    virtual package provided by compilers that depend on libc6-dev-i386.
    But this is not the case here.

    This is actually not correct. gcc-multilib is required even for
    compiling with another gcc-X-mutilib compiler as it provides the /usr/include/linux/asm symlink.

    I'll therefore revert the change in the next upload. Feel free to report
    bugs against gcc-multilib or gcc-X-multilib if you feel it's provided in
    the wrong package.

    I suppose you meant /usr/include/asm.

    OK, I've just reported:
