[Buildroot] Problem compiling busybox with libpam

[Buildroot] Problem compiling busybox with libpam

[Spider]

I was using buildroot to compile busybox and got the following error
when I add libpam using "make busybox-menuconfig". ?(The output is
below).
How can I get libpam to compile without this errors? If I "make clean"
and remake everything from scratch will it work? (I wil try this
tomorrow because of the time to compile and fear of configuration files changes)

I searched for a similar problem but didnt find anything on
documentation. Do I need to manually supply security/pam_appl.h and
security/pam_misc.h? Where to find them?

It looks like Busybox PAM support depends on the PAM library, for which
we don't have a package yet.

So you would need to :

 * Create a Buildroot package for
   ftp://ftp.kernel.org/pub/linux/libs/pam/library/Linux-PAM-1.1.3.tar.bz2

 * Create a sub-option in the Busybox Buildroot package to
   enable/disable PAM support. This option should select the PAM
   library package created at the previous step.

 * In package/busybox/busybox.mk, if PAM support is enabled, then tweak
   the Busybox configuration file, and add the dependencies on the PAM
   library.

Regards,

Thomas

There's no pam support in uClibc/buildroot, so this can only work if you
use an external glibc toolchain with pam support.

Please follow up on the buildroot list rather than here on busybox.

Hum, I'm not familiar at all with PAM, but it looks like it's a separate
library from the C library. At least on Debian systems,
security/pam_*.h are coming from libpam0g-dev, and the library is in
libpam0g, both of which are coming from the Linux-PAM project it seems.

How does it relate to the choosen C library ?
