glibc compiling with kernel 2.5.70-bk17

Good morning,

I'm trying to compiling several version of the glibc but always during the "make" I obtain these errors:

I have:
2.5.70-bk17 (even if the 2.5.70-bk15 is shown on the path)
gcc 3.3
binutils 2.13.92

Someone have an idea? :)

Thanks,

Yes, the kernel headers are currently borked for compiling userspace C libraries. The fix is going to take either a large effort to get a sanitized set of userspace kernel headers created, or someone to be willing to accept patches that fix the problems with the existing headers even though userspace is not supposed to be using them.

I did get glibc 2.3.2 compiled with gcc 3.3 against the 2.5.70 headers with only 3 changes made to the glibc source.

The result on the other hand wasn't pretty. Most programs did run fine, "ls" was not one of them. It would segfault. (Note to self: If glibc's "make check" fails, don't install it.)

Your first comment is something I had wondered about for a while. A stable set of userspace kernel headers. That would be nice. Of course changes could be made to reflect new kernel interfaces. So they should still be distributed with the kernel source. Then glibc could be compiled against those updates, and the headers installed as the system default. But it wouldn't be so forbidden for userspace to touch them.

Yes, this is the "ABI headers" project that has been discussed extensively on this list. It's pretty important, but unlikely to happen in time for 2.6.
