Talk:Advanced configuration

I need to convert the hardware platform of OE from ARM into X86,but I don't know the correct step, I tried as follows:

     Change the contents of file  ~/stuff/build/conf/local.conf, the changes are:
                          MACHINE = "i586-generic";
                          #TARGET_ARCH = "arm"
                          TARGET_OS = "linux"

then, build ,but a error occured:

 ERROR: Build of /home/build/stuff/openembedded/packages/xorg-lib/libx11_1.2.1.bb do_compile failed
 ERROR: Task 3164 (/home/build/stuff/openembedded/packages/xorg-lib/libx11_1.2.1.bb, do_compile) failed

Now,I don't know what to do, I tried to do some changes,but this error still exit,call for help!
