Comment 1 David Seifert gentoo-dev 2016-01-26 08:36:46 UTC
Hi Steffen, could you please retry? It works for me, likely as some dependency is pulling in pthreads.
Comment 2 Steffen Hau 2016-01-26 10:27:32 UTC
Hi David,

I checked again an it still fails. I think it's not good to rely on other packages to include -pthread, as the package uses it it should check and add it on its own. My simple patch still works.

Best regards,
Comment 3 David Seifert gentoo-dev 2016-02-13 18:15:22 UTC
Hi Steffen,
I've added AX_PTHREAD to the and include PTHREAD_CFLAGS unconditionally in the LIBS. This should hopefully solve the issue, could you give it another go once -r3 trickles down to you?

    app-cdr/cdrdao: Link to libpthread unconditionally
    Gentoo-Bug: 548004, 520988
    * EAPI=6
    * Use AX_PTHREAD to properly detect pthread flags
    * Use AM_PROG_AR instead of toolchain-funcs.eclass
    * Amend patches for -p1
    * Fix -Werror=format-security errors
