还是挡不住Ubuntu12.04的诱惑，，升级啦。在已经配置好的Ubuntu 11.10 Android开发环境下（请参看），升级Ubuntu系统到12.04，参考 。
目前没遇到啥大的问题。只是编译（emulator版本，device版本没有问题。）的时候有如下错误：
1.错误：/usr/bin/ld: cannot find -lGL解决办法：重新建立链接就好了。$ ldd libGLES_CM_translator.so linux-gate.so.1 => (0xf77a7000) libGL.so.1 => /usr/lib/i386-linux-gnu/mesa/libGL.so.1 (0xf76ed000) libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf76e8000) libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf76cc000) libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xf75e7000) libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf75bb000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7416000) libglapi.so.0 => /usr/lib/i386-linux-gnu/libglapi.so.0 (0xf7400000) libXext.so.6 => /usr/lib/i386-linux-gnu/libXext.so.6 (0xf73ed000) libXdamage.so.1 => /usr/lib/i386-linux-gnu/libXdamage.so.1 (0xf73e9000) libXfixes.so.3 => /usr/lib/i386-linux-gnu/libXfixes.so.3 (0xf73e3000) libX11-xcb.so.1 => /usr/lib/i386-linux-gnu/libX11-xcb.so.1 (0xf73e0000) libX11.so.6 => /usr/lib/i386-linux-gnu/libX11.so.6 (0xf72ac000) libxcb-glx.so.0 => /usr/lib/i386-linux-gnu/libxcb-glx.so.0 (0xf7293000) libxcb.so.1 => /usr/lib/i386-linux-gnu/libxcb.so.1 (0xf7272000) libXxf86vm.so.1 => /usr/lib/i386-linux-gnu/libXxf86vm.so.1 (0xf726c000) libdrm.so.2 => /usr/lib/i386-linux-gnu/libdrm.so.2 (0xf725f000) /lib/ld-linux.so.2 (0xf77a8000) libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xf7241000) libXau.so.6 => /usr/lib/i386-linux-gnu/libXau.so.6 (0xf723c000) libXdmcp.so.6 => /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0xf7235000) librt.so.1 => /lib/i386-linux-gnu/librt.so.1 (0xf722c000)/out/host/linux-x86/lib$

解决办法：重新编译就好啦。host C: libpcre <= out/host/linux-x86/obj/STATIC_LIBRARIES/libpcre_intermediates/pcre/src/pcre_chartables.chost StaticLib: libpcre (out/host/linux-x86/obj/STATIC_LIBRARIES/libpcre_intermediates/libpcre.a)host Executable: a3dconvert (out/host/linux-x86/obj/EXECUTABLES/a3dconvert_intermediates/a3dconvert)out/host/linux-x86/obj/STATIC_LIBRARIES/colladadom_intermediates/colladadom.a(domPhysics_scene.o): In function `domPhysics_scene::registerElement(DAE&)’:external/collada/src/1.4/dom/domPhysics_scene.cpp:51: undefined reference to `domInstance_force_field::registerElement(DAE&)’out/host/linux-x86/obj/STATIC_LIBRARIES/colladadom_intermediates/colladadom.a(domInstance_physics_model.o): In function `domInstance_physics_model::registerElement(DAE&)’:/external/collada/src/1.4/dom/domInstance_physics_model.cpp:45: undefined reference to `domInstance_force_field::registerElement(DAE&)’collect2: ld returned 1 exit statusmake: *** [out/host/linux-x86/obj/EXECUTABLES/a3dconvert_intermediates/a3dconvert] Error 1
