Re: CT_LIBC_GLIBC_MIN_KERNEL(_VERSION)?


Esben, All,

Nope, not as far as I know... :-)

CT_LIBC_GLIBC_MIN_KERNEL_VERSION is the value the user enters in the
menuconfig, CT_LIBC_GLIBC_MIN_KERNEL is the value that scripts shall
test.

CT_LIBC_GLIBC_MIN_KERNEL  gets its value either from the configured
kernel version in the kernel section, or from the user supplied version.

What version is that? In the latest release (1.10.0), glibc and eglibc code
paths have been merged, and there is a single code path that computes the
minimal kernel version. See:
  scripts/build/libc/glibc-eglibc.sh-common@285

(although there appears to be an issue in tht code when the user choose to
let ./configure decide. I'll look at it.)
