I think you're using an old version of Buildroot, because the options are now organized in a different way (I've cleaned them up because they were quite messy). Now, we have a top-level option [ ] X.org X Window System, X11R7, release 7.4 Inside this options, we have : X Window System server type (TinyX) ---> X11R7 Servers ---> X11R7 Libraries ---> X11R7 Applications --> X11R7 Fonts --> X11R7 X Protocols --> X11R7 Utilities --> X11R7 Other data --> So, once you've enabled X.org X Window System, X11R7, release 7.4, you are able to choose the server type, and there you have two choices : * TinyX, which is in fact now known as Kdrive. It is a standalone X server, which only supports a few hardware access solutions: framebuffer, VESA, etc. If you want video-card specific drivers, then, from my understanding, you cannot use TinyX/Kdrive * The modular X.org, which is similar to the one you have in any Linux distro, which allows you to compile hardware-specific drivers. If you select this type, a new entry "X11R7 Drivers --->" will appear. In your case, you probably want the modular X.org. > Here comes the problem. During compiling, I got the following error > log.

No, libtool doesn't need the libraries to be installed on the host. It might work-around some Buildroot issue, but it shouldn't be needed. > I really think the path is the problem, but I don't know how to > change it as I'm not familiar at all with Libtool. > Some advices for me? Could you try with Buildroot 2010.02, and if it still doesn't work, send us your .config ? Thanks!
