Erik,  I am dreadfully sorry.. I have been looking through the list throughout the day and... yes it does look rather impatient.  opus ummmm

I see your post... I had written the last one and held off for a bit then just sent it 5 min after your respond was posted to the list; had not received it when I sent mine.  I am glad to hear it has been going through.. because usually the lists are very responsive; however I have not heard anything in a while on some.. and had thought my server was rejecting them or just getting lost.  But all in all glad to know everything is fine.  (We have been tweaking the server for spam and had noticed some legit mail was being blocked but since fixed.)

This is what I have been doing for some years, I do hope it is correct.  When compiling my own source and I have a link in /usr/include/linux pointing 

lrwxrwxrwx 1 root root 26 Jun  2 13:21 /usr/include/linux -> ../src/linux/include/linux/

Within /usr/src/linux/include/linux I find a link asm -> asm-x86_64

 ../include/asm # cat errno.h
#ifndef _X8664_ERRNO_H
#define _X8664_ERRNO_H

#include <asm-generic/errno.h>

#endif

(I do not find an asm-amd64 and I think the asm-x86_64 is the proper directory.)  My working kernel I am using now was my first AMD kernel compiled and before that it has been PPC all these years with some intel kernels of late working on some servers.

scripts/kconfig/mconf.c does have errno.h in the file.

 ../src/linux # grep errno.h scripts/kconfig/mconf.c
#include <errno.h>

grepping EINTR I found this:
                                if (errno == EINTR || errno == EAGAIN)

Ummmm, I am showing my lack of programing knowledge here, what is EAGAIN? 

grepping EAGAIN I get the same response as above:
                                if (errno == EINTR || errno == EAGAIN)

Ok.. now looking over that.. I did have a slight brain freeze.  When you had mentioned about the headers and includes.. I had forgotten about my link in /usr/include pointing to the /usr/src/linux/include and 'linux' was the new 2.6.17.1 kernel source.  That being said I moved the linux link to my old source and did a make xconfig and it worked but different errors in the terminal came up but the gui xconfig did display, as opposed to the 2.6.17.1 source it had not. (I can list those errors but I did not want to complicate the issue and sticking to the current issue at hand.)

So, it does look like the new 2.6.17.1 code has a bit minor issue with me. 


I do hope that helps...and thank you very much :).
