You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

Subject: Compile error with glibc 2.3.2 + Linux 2.6.5 ARCH=x86_64

I am getting compiler errors when trying to compile glibc 2.3.2 using
|
|
the kernel headers from linux 2.6.5. The headers from linux 2.6.3 work
|
|
fine.
|
|
|
|
I've traced the cause of the problem to a change made in
|
|
./include/asm-x86_64/unistd.h in the 2.6.4 release.
|

Within glibc, ./sysdeps/unix/sysv/linux/x86_64/syscall.S ends up
|
|
including this file, which chokes the assembler with the struct
|
|
declarations in the above #include's.

|
|

|
|
|
|
There are also errors about conflicting re-declarations further along in
|
|
the glibc build.

|
|
|
|
Changing the '#ifndef __ASSEMBLY__' to '#if ((!defined __ASSEMBLY__) &&
|
|
(defined __KERNEL__))' clears up the problem. My patch is below.
