When compile compiz-0.5.0 with "-Wl,--as-needed" LDFLAGS, following error occurs ikk@toybox ~ $LIB_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ LIBGL_ALWAYS_INDIRECT=ture compiz --indirect-rendering --replace ini & [3] 29819 ikk@toybox ~ $ compiz: symbol lookup error: /usr/lib64/compiz/libpng.so: undefined symbol: png_check_sig ikk@toybox ~ $gtk-window-decorator --replace & [3] 29822 ikk@toybox ~ $ gtk-window-decorator: Could not acquire decoration manager selection on screen 0 display ":0.0" compiz won't start, and without windows decorations. However if I don't set the "-Wl,--as-needed" LDFLAGS, compiz will start without any problem. ikk@toybox ~ $ LIB_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ LIBGL_ALWAYS_INDIRECT=ture compiz --indirect-rendering --replace ini & [1] 9232 ikm@toybox ~ $ gtk-window-decorator --replace & [2] 9233 Reproducible: Always Steps to Reproduce: 1. set "-Wl,--as-needed" to LDFLAG in /etc/make.conf 2. emerge -av compiz 3.
