vd_bugzilla-jp_bug-1476_attachment-1656_for-mozfx-0.9.3.patch、vd_mozfx-0.10.1_without-gnome-and-gconf.patch、mozilla-1.8a5-gtk2-composition-fix.diff を当ててのビルド途中でエラー。

調べてみると、FTC_Image_Cache が FTC_ImageCache に、FTC_Image_Desc が FTC_ImageType に代わったなどなど。 探してみると firefox-0.7.3-freetype-compile.patch なる NetBSD 由来のパッチを見つけたのでこれを当ててみると、ビルド成功。動作も問題ないようだ。 Mozilla 本家には Bug 234035 freetype2 2.1.8 compile error: FTC_Image_Cache_* APIs are not available any more として登録されている。

_ [comp] X.Org の Composite 拡張

nvidia + X.Org で Composite 拡張が有効だと GLX 拡張が使えない。

% glxgears
Xlib:  extension "GLX" missing on display ":0.0".
glxgears: Error: couldn't get an RGB, Double-buffered visual.

調べてみると、xorg.conf の Device セクションに

Option "AllowGLXWithComposite" "true"

を追加してやればよいようだ。

Option “AllowGLXWithComposite” “boolean”

Enables GLX even when the Composite X extension is loaded. ENABLE AT YOUR OWN RISK. OpenGL applications will not display correctly in many circumstances with this setting enabled. Default: GLX is disabled when Composite is loaded.

ref. /usr/share/doc/nvidia-glx/README.gz

でも危険な模様。 また、fglrx + X.Org で Composite 拡張が有効だと DRI を無効にされ、XVideo 拡張も使えない。

It seems there is no Xvideo support for your video card available.
Run 'xvinfo' to verify its Xv support and read DOCS/HTML/en/video.html#xv!
See 'mplayer -vo help' for other (non-xv) video out drivers. Try -vo x11

今のところ fglrx では Composite 拡張を無効にするしかないようだ。
