ubuntu12.04Desktop安装Cadence SPB 16.3 Linux出现Unable to resolve function！

在ubuntu 12.04 Desktop上安装了Cadence SPB 16.3 Linux，用论坛上的破解后，运行allegro，在终端中出现
Unable to resolve function glXQueryExtension
Unable to resolve function glXMakeCurrent
Unable to resolve function glXQueryExtension
Unable to resolve function glXMakeCurrent
Unable to resolve function glXUseXFont
Unable to resolve function glXUseXFont
这些错误，如何解决啊?

没升级S19时，也这样！如何解决啊?着急～～～～～～～～

prepend the path to your 32bit opengl libraries to LD_LIBRARY_PATH, for example:
$ export LD_LIBRARY_PATH=/usr/lib32/opengl/nvidia/lib/://$LD_LIBRARY_PATH
~
上面双斜杠处，应该是单斜杠的，因为有转义符，无奈写成那样了。自己去掉吧。

Unable to resolve function glXQueryExtension
Unable to resolve function glXMakeCurrent$ _( N- z0 e5 R$ j
Termination codes: exit=3, signal=11, errno=2
后来安装了xf86-video-intel-2.10.0.tar.bz2及fglrx后终于成功启动

安装16.3 我也出现这个问题了
