hi Ray
I got the catch now .
The problem is with the header files provided by red hat 8.0
They are incomplete
i downloaded one kernel tree . include header files of that tree and it went smooth But again i am facing one problem
Now i want to compile that sourse but it is throwing me some error in make bzImage I think may be its due to the patch i havent downloaded or maybe its something else Do u have any clue why make bzImage would fail
It says error intimer.cmultiple types for times
"make bzImage" can fail for any number of reasons, many of which are the direct resut of not following to the letter the procedure described in /usr/src/linux/README (your path might vary a bit from this). Check to be sure that you followed all the steps specified there.
As to your specifics ... I don't even try to interpret paraphrased or truncated error messages from make or gcc. Interpreting the actual output is hard enough. If you want help at that level of detail, post the complete error line(s), with enough context to let me (and others) see where in the compile process you are. And please mention which kernel-source package is involved (what kernel version and from what distro - are you getting your source from RH rpms or are you downloading from elsewhere?), and whether you've made any changes to the source.
Unpatched kernel trees from the big-name distros may contain bugs, but it's rare for one not to compile if you follow the instructions in the README file. (Rare but not impossible -- the Debian 2.4.20 source I downloaded recently would not compile if SMP support was turned off; go figure.) So I doubt a missing patch is your problem.

2. Are you #include'ing, in these cases, the
uaccess.hthat is located in/usr/include/asm, or one that comes as part of kernel source? (I ask because the context of your questions is "module level programming".) If the second, what kernel, and are you compiling for i86 hardware?

3. The lines you (sort of) quote look more like warnings than errors, but it is hard to be sure from the small fragments you provide. Could you please post a complete "error" line or two?
4. What is "my compiler"? Some version (which) of gcc? Of g++? Or are you using some other compiler?
