The Problem seems to be the '-static' flag, beat me if i'm wrong...

[Comment 2 Keith Constable 2004-02-24 17:21:09 UTC]

You are correct.  If I remove -all-static from LDFLAGS in ./examples/Makefile it compiles correctly.  Is this a valid fix or just a workaround?

[Comment 4 Olivier Castan 2004-02-29 10:56:14 UTC]

Since the programs in examples are registred as with "noinst_" prefix in Makefile.am they won't be installed. It's useless to build them since portage will erase the build dir.

So changing to subdir lib before building and installing seems to be a correct workaround :

You have to install headers, too:

src_install() {
    cd ${S}/lib
    make DESTDIR=${D} install || die
    cd ${S}/include
    make DESTDIR=${D} install || die
    cd ${S}

    dodoc README

I tried editing the ebuild with these changes, but I still get the same error.

[Comment 7 Curt Parker (dirtboy) 2004-03-08 13:21:00 UTC]

Scratch that, left the major change out.  Changes work great.

libtheora-1.0_alpha2-r1.ebuild

Just in case this bug isn't getting fixed because the media-video herd is
overworked (or just lazy), here's a working ebuild with the above fixes
applied.

Created attachment 27695 [details]
libtheora-1.0_alpha3.ebuild

Version bumped.
Added sed in src_unpack for this bugs.
Removed media-libs/libsdl from DEPEND. SDL is needed by
${S}/examples/player_example, but the ebuild does not install it.
Added docdir in src_install.

[Comment 10 Keith Constable 2004-03-20 11:08:44 UTC]

Matsuu, yeah, that's a smarter way to do it.

Matsuu's ebuild Works For Me(TM).

sorry for delay, in cvs
