custom uClibc problems

Hi people

I have followed the tutorial from microtronixs on how to build a custom uClibc library. After I have run the menuconfig I then begin the make from the toplevel makefile. It compiles for some time and then it comes to a halt with 2 errors. Has this happend for any of you guys and how did you fix it???

I have just taken the last lines from the command prompt so you can see the errors.

[CODE]In file included from ../../include/asm/page.h:27,

    Hmm... sounds like the Make process couldn't find the autoconf file that's generated during the building of a linux kernel.

    Things to confirm:

    - Double check the Linux Build Location option in the uClibc menuconfig. It should point to a kernel project build directory, not to the linux source tree.

    - The kernel project that's specified within the uClibc menuconfig must be built at least once to generate the autoconf.h file

    - After building the kernel, does an autoconf.h file exist inside the build directory? I think it should be in

    <kernel_project>/build/include/linux

    Hope that helps, if not let me know and I&#39;ll dig a bit deeper.

    Hi Ken

    Thx for your help it works now. Stupid me. In the future I should perhaps follow the guide a bit better.

    But again thanks!!!

    Hey, don&#39;t beat yourself up over it. In fact, if you have any suggestions for the documentation, please feel free to PM me about it.

    Glad I could help.
