I have been trying to get splashy to work on gentoo and ran into a small directfb bug that seems to have been around for some time. When DirectFB is built with the "sysfs" USE flag linking against the library fails with the following errors. then mv -f ".deps/splashy-splashy_functions.Tpo" ".deps/splashy-splashy_functions.Po"; else rm -f ".deps/splashy-splashy_functions.Tpo"; exit 1; fi /bin/sh ../libtool --tag=CC --mode=link i686-pc-linux-gnu-gcc -O2 -march=athlon64 -msse3 -fomit-frame-pointer -pipe -Wall -Werror -DG_DISABLE_ASSERT -DG_DISABLE_CHECKS -o splashy -all-static -static-libgcc -Wl,-uIDirectFBFont_Default -Wl,-uIDirectFBFont_FT2 -Wl,-uIDirectFBImageProvider_PNG splashy-splashy_main.o splashy-splashy_functions.o libsplashycnf.la libsplashy.la -lpthread -lm -lglib-2.0 -static /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o /usr/lib/directfb-0.9.25/wm/libdirectfbwm_default.o /usr/lib/directfb-0.9.25/interfaces/IDirectFBFont/libidirectfbfont_ft2.o -lfreetype /usr/lib/directfb-0.9.25/interfaces/IDirectFBFont/libidirectfbfont_default.o /usr/lib/directfb-0.9.25/interfaces/IDirectFBImageProvider/libidirectfbimageprovider_png.o -lpng -lz -lm /usr/lib/directfb-0.9.25/inputdrivers/libdirectfb_keyboard.o -L/usr/lib -ldirectfb -lfusion -ldirect -lpthread -lz i686-pc-linux-gnu-gcc -O2 -march=athlon64 -msse3 -fomit-frame-pointer -pipe -Wall -Werror -DG_DISABLE_ASSERT -DG_DISABLE_CHECKS -o splashy -static -static-libgcc -Wl,-uIDirectFBFont_Default -Wl,-uIDirectFBFont_FT2 -Wl,-uIDirectFBImageProvider_PNG splashy-splashy_main.o splashy-splashy_functions.o /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o /usr/lib/directfb-0.9.25/wm/libdirectfbwm_default.o /usr/lib/directfb-0.9.25/interfaces/IDirectFBFont/libidirectfbfont_ft2.o /usr/lib/directfb-0.9.25/interfaces/IDirectFBFont/libidirectfbfont_default.o /usr/lib/directfb-0.9.25/interfaces/IDirectFBImageProvider/libidirectfbimageprovider_png.o /usr/lib/directfb-0.9.25/inputdrivers/libdirectfb_keyboard.o ./.libs/libsplashycnf.a ./.libs/libsplashy.a /var/tmp/portage/media-gfx/splashy-0.3.6/work/splashy-0.3.6/src/.libs/libsplashycnf.a /usr/lib/libglib-2.0.a /usr/lib/libfreetype.a /usr/lib/libpng12.a -lm -L/usr/lib /usr/lib/libdirectfb.a /usr/lib/libfusion.a /usr/lib/libdirect.a -ldl -lpthread -lz /usr/lib/libglib-2.0.a(gutils.o): In function `g_get_any_init_do': (.text+0x121b): warning: Using 'getpwuid' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/libglib-2.0.a(gutils.o): In function `g_get_any_init_do': (.text+0x120e): warning: Using 'setpwent' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/libglib-2.0.a(gutils.o): In function `g_get_any_init_do': (.text+0x1227): warning: Using 'endpwent' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/libglib-2.0.a(gutils.o): In function `g_get_any_init_do': (.text+0x10cf): warning: Using 'getpwnam_r' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/libglib-2.0.a(gutils.o): In function `g_get_any_init_do': (.text+0x1117): warning: Using 'getpwuid_r' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/libdirect.a(log.o): In function `parse_host_addr': (.text+0x231): warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o: In function `directfb_fbdev': (.text+0x4c1c): undefined reference to `sysfs_get_mnt_path' /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o: In function `directfb_fbdev': (.text+0x4cb5): undefined reference to `sysfs_open_class_device' /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o: In function `directfb_fbdev': (.text+0x4cc7): undefined reference to `sysfs_get_classdev_device' /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o: In function `directfb_fbdev': (.text+0x4ce1): undefined reference to `sysfs_get_device_attr' /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o: In function `directfb_fbdev': (.text+0x4d18): undefined reference to `sysfs_get_device_attr' /usr/lib/directfb-0.9.25/systems/libdirectfb_fbdev.o: In function `directfb_fbdev': (.text+0x4db2): undefined reference to `sysfs_close_class_device' collect2: ld returned 1 exit status make[2]: *** [splashy] Error 1 make[2]: Leaving directory `/var/tmp/portage/media-gfx/splashy-0.3.6/work/splashy-0.3.6/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/media-gfx/splashy-0.3.6/work/splashy-0.3.6' make: *** [all] Error 2 More details here http://forums.gentoo.org/viewtopic-t-326522.html I tracked this down to directfb itself, directfb-config does not set -lsysfs so linking against it fails as noted above. 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@

should really convert the additional libs to Libs.private Libs: -L${libdir} -ldirectfb Libs.private: @THREADLIB@ @DYNLIB@ @ZLIB_LIBS@ @SYSFS_LIBS@ @OSX_LIBS@
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
