I went looking into why this was happening on Gentoo and not other distros and it seems this is because they are ALL patching the DirectFB sources. I have attached a simple patch that fixed the problem. Please add this patch to the ebuild. I have tested it in my overlay and it works as it should. diff -uNr DirectFB-0.9.25.1/directfb-config.in DirectFB-0.9.25.1-sysfs/directfb-config.in --- DirectFB-0.9.25.1/directfb-config.in 2005-12-01 11:51:06.000000000 -0700 +++ DirectFB-0.9.25.1-sysfs/directfb-config.in 2007-11-27 21:45:03.000000000 -0700 @@ -300,7 +300,7 @@ libs=-L@libdir@ if test "$lib_directfb" = "yes"; then - libs="$libs -ldirectfb -lfusion -ldirect @THREADLIB@ @ZLIB_LIBS@" + libs="$libs -ldirectfb -lfusion -ldirect @THREADLIB@ @ZLIB_LIBS@ @SYSFS_LIBS@" if test -z "$echo_static"; then libs="$libs @DYNLIB@" diff -uNr DirectFB-0.9.25.1/directfb.pc.in DirectFB-0.9.25.1-sysfs/directfb.pc.in --- DirectFB-0.9.25.1/directfb.pc.in 2005-10-18 17:14:04.000000000 -0600 +++ DirectFB-0.9.25.1-sysfs/directfb.pc.in 2007-11-27 21:44:04.000000000 -0700 @@ -7,5 +7,5 @@ Description: Graphics and windowing library for the Linux frame buffer device Version: @VERSION@ Requires: fusion direct -Libs: -L${libdir} -ldirectfb @THREADLIB@ @DYNLIB@ @ZLIB_LIBS@ @OSX_LIBS@ +Libs: -L${libdir} -ldirectfb @THREADLIB@ @DYNLIB@ @ZLIB_LIBS@ @SYSFS_LIBS@ @OSX_LIBS@ Cflags: @THREADFLAGS@ -I@INCLUDEDIR@ linuxras@gmail.com 2007-11-28 17:02:58 0000 Created an attachment (id=137249) Patch against DirectFB-0.9.25.1 vapier@gentoo.org 2007-12-02 21:17:14 0000 should really convert the additional libs to Libs.private Libs: -L${libdir} -ldirectfb Libs.private: @THREADLIB@ @DYNLIB@ @ZLIB_LIBS@ @SYSFS_LIBS@ @OSX_LIBS@ vapier@gentoo.org 2007-12-02 22:21:13 0000 fixed in DirectFB-1.1.0 ... thanks for the report/patch ! i'll see about opening a bug report upstream about the Libs.private thing 137249 2007-11-28 17:02 0000 Patch against DirectFB-0.9.25.1 DirectFB-0.9.25.1-sysfs.patch text/plain ZGlmZiAtdU5yIERpcmVjdEZCLTAuOS4yNS4xL2RpcmVjdGZiLWNvbmZpZy5pbiBEaXJlY3RGQi0w LjkuMjUuMS1zeXNmcy9kaXJlY3RmYi1jb25maWcuaW4KLS0tIERpcmVjdEZCLTAuOS4yNS4xL2Rp cmVjdGZiLWNvbmZpZy5pbgkyMDA1LTEyLTAxIDExOjUxOjA2LjAwMDAwMDAwMCAtMDcwMAorKysg RGlyZWN0RkItMC45LjI1LjEtc3lzZnMvZGlyZWN0ZmItY29uZmlnLmluCTIwMDctMTEtMjcgMjE6 NDU6MDMuMDAwMDAwMDAwIC0wNzAwCkBAIC0zMDAsNyArMzAwLDcgQEAKICAgICAgIGxpYnM9LUxA bGliZGlyQAogCiAgICAgICBpZiB0ZXN0ICIkbGliX2RpcmVjdGZiIiA9ICJ5ZXMiOyB0aGVuCi0J IGxpYnM9IiRsaWJzIC1sZGlyZWN0ZmIgLWxmdXNpb24gLWxkaXJlY3QgQFRIUkVBRExJQkAgQFpM SUJfTElCU0AiCisJIGxpYnM9IiRsaWJzIC1sZGlyZWN0ZmIgLWxmdXNpb24gLWxkaXJlY3QgQFRI UkVBRExJQkAgQFpMSUJfTElCU0AgQFNZU0ZTX0xJQlNAIgogCiAJIGlmIHRlc3QgLXogIiRlY2hv X3N0YXRpYyI7IHRoZW4KIAkgICAgbGlicz0iJGxpYnMgQERZTkxJQkAiCmRpZmYgLXVOciBEaXJl Y3RGQi0wLjkuMjUuMS9kaXJlY3RmYi5wYy5pbiBEaXJlY3RGQi0wLjkuMjUuMS1zeXNmcy9kaXJl Y3RmYi5wYy5pbgotLS0gRGlyZWN0RkItMC45LjI1LjEvZGlyZWN0ZmIucGMuaW4JMjAwNS0xMC0x OCAxNzoxNDowNC4wMDAwMDAwMDAgLTA2MDAKKysrIERpcmVjdEZCLTAuOS4yNS4xLXN5c2ZzL2Rp cmVjdGZiLnBjLmluCTIwMDctMTEtMjcgMjE6NDQ6MDQuMDAwMDAwMDAwIC0wNzAwCkBAIC03LDUg KzcsNSBAQAogRGVzY3JpcHRpb246IEdyYXBoaWNzIGFuZCB3aW5kb3dpbmcgbGlicmFyeSBmb3Ig dGhlIExpbnV4IGZyYW1lIGJ1ZmZlciBkZXZpY2UKIFZlcnNpb246IEBWRVJTSU9OQAogUmVxdWly ZXM6IGZ1c2lvbiBkaXJlY3QKLUxpYnM6IC1MJHtsaWJkaXJ9IC1sZGlyZWN0ZmIgQFRIUkVBRExJ QkAgQERZTkxJQkAgQFpMSUJfTElCU0AgQE9TWF9MSUJTQAorTGliczogLUwke2xpYmRpcn0gLWxk aXJlY3RmYiBAVEhSRUFETElCQCBARFlOTElCQCBAWkxJQl9MSUJTQCBAU1lTRlNfTElCU0AgQE9T WF9MSUJTQAogQ2ZsYWdzOiBAVEhSRUFERkxBR1NAIC1JQElOQ0xVREVESVJACg==
