libnsl-0-r1.ebuild

Although net-libs/libnsl is a dummy ebuild, it should follow the other packages and have multilib USE flags pointing to glibc in order to satisfy current stable packages.

Attached is my proposed ebuild to solve this.
Comment 1 Dennis Schridde 2018-01-01 22:21:49 UTC
In bug #643052 I proposed net-libs/libnsl-0 to be changed in a way similar to this:
```
inherit multilib-minimal
if [[ "${MULTILIB_USEDEP}" != "${DEFAULT_ABI}" ]] ; then
  USEDEP=multilib
fi
DEPEND="elibc_glibc? ( <sys-libs/glibc-2.26[${USEDEP}] )"
```

This is unlikely to work as MULTILIB_USEDEP usually contains much more than one ABI

For other (and shamefully obvious) reasons this also will not work.  Please forget that I ever proposed it...

Since the other (and only working) way of spelling out the USE dependencies one by one feels rather cludgey: Maybe we could create a function that derives a dependency string from the list of all ABIs supported by KEYWORDS and the package to depend on, if we are in a multilib situation?  I.e. something that would be called as follows:
KEYWORDS="x86 amd64 mips"
DEPEND="sys-libs/glibc
        $(generate_depend 'sys-libs/glibc[multilib]')"
And produce something like:
DEPEND="sys-libs/glibc
        abi_x86_32? ( abi_x86_64? ( sys-libs/glibc[multilib] ) )
        abi_x86_32? ( abi_x86_x32? ( sys-libs/glibc[multilib] ) )
        abi_x86_64? ( abi_x86_x32? ( sys-libs/glibc[multilib] ) )
        abi_mips_n64? ( abi_mips_n32? ( sys-libs/glibc[multilib] ) )
        abi_mips_n64? ( abi_mips_o32? ( sys-libs/glibc[multilib] ) )
        abi_mips_n32? ( abi_mips_o32? ( sys-libs/glibc[multilib] ) )"

ebuild patch

Here's a simpler solution.

To quote my commit message:

We don't actually want to RDEPEND on sys-libs/glibc[multilib] since the
multilib USE flag is forced on/off by the user's profile, and a mismatch
would just cause confusion.
Comment 5 Brian Evans (RETIRED) gentoo-dev 2018-04-29 20:04:18 UTC
This looks completed

    net-libs/libnsl: inherit multilib-build in the dummy ebuild
    
    This populates IUSE with the appropriate flags.
