Comment 1 Ulrich Müller gentoo-dev 2017-12-09 00:08:09 UTC
Adding the following two lines right at the beginning of src_configure appears to fix the problem here (17.0 profile, gcc-6.4.0):

    test-flags -no-pie >/dev/null && append-flags -no-pie
    filter-flags -pie

    app-editors/xemacs: Use system malloc and -no-pie
    For 21.4 use system malloc on all architectures. For both 21.4 and 21.5 use -no-pie option
    since xemacs can't be built with positions indipendent code yet. This is for adopting
    to the 17.0 profiles which defaults to use PIE.

Comment 3 vsync 2017-12-10 22:40:32 UTC
I ran into the exact same issue with xemacs-21.5.34-r4.  Once I ran "emerge --sync" I was able to build.

Is it normal to edit the ebuild in-place, without bumping the revision number?  This isn't intended as a dig, just I don't understand everything about Gentoo versioning mechanisms/policy.
Comment 4 Mats Lidell gentoo-dev 2017-12-10 23:05:05 UTC
Thanks for verifying that it works for you.

About version bumps read:

My conclusion was the build would be broken for users switching to the new 17.0 profile which warranted that it was done in place with no revision bump.
