Subject: popen2 popen call

Hi,

I am using vanilla kernel 2.6.31-rc7, glibc 2.10.x on a Core 2 Duo system.

When the popen call is made in sshd/session.c I get a error from strerror 
of "Function not Implemented".  I googled a bit and found that there is 
sometimes an problem between the way the kernel and glibc are compiled 
that causes glibc not to find the popen2 call in the kernel.  The fix 
seemed to imply I need a certain processor choice when compiling the 
kernel.

Strangely, simple popen test programs seem to work OK.

Can anyone shed some light on this for me?  I would like to get this to 
work, so my X11 forwarding works in ssh.

BTW, kernels before 2.6.27 don't seem to cause the problem to manifest 
itself.

Thanks!

Fred
