my notepad is lenovo E41G.and setup Centos 5.3 x86_64 OS Configuration the following error when wine checking for pthread_create in -lpthread... yes checking for X... no configure: error: X 32-bit development files not found. Wine will be built without X support, which probably isn't what you want. You will need to install 32-bit development packages of Xlib/Xfree86 at the very least. Use the --without-x option if you really want this.
