Bug 638282 – sys-apps/iproute2-4.14.0 has automagic dependency on dev-libs/elfutils

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Samuel Holland 2017-11-20 22:39:16 UTC]

It looks like HAVE_ELF needs to be set in src_configure(), and possibly a USE flag added. libelf is used for parsing of compiled eBPF programs by ip and tc.

https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/tree/configure?h=v4.14.0#n264

Otherwise I am getting this on a machine without elfutils:
# ip
Error loading shared library libelf.so.1: No such file or directory (needed by /bin/ip)
Error relocating /bin/ip: elf_getdata: symbol not found
Error relocating /bin/ip: elf_end: symbol not found

On the machine with elfutils installed:

ip => /bin/ip (interpreter => /lib/ld-musl-x86_64.so.1)
    libelf.so.1 => /usr/lib/libelf.so.1

    libmnl.so.0 => /lib/libmnl.so.0
    libc.so => /usr/lib/libc.so

Working on it, putting behind USE=minimal

    sys-apps/iproute2: fix automagic libelf dep.
    
    iproute2 has been automagically linking against libelf for a long time.
    It is only used for eBPF programs, so isn't critical in most cases.
    
    Declare the dep via virtual/libelf, but put it behind USE=-minimal, as
    with libmnl.
