Thomas, All,

On 2014-06-08 08:30 +0200, Thomas Petazzoni spake thusly:

libbsd checks whether the toolchain has support for .init_array, which
it checks as thus:

    /* Look for a known libc that supports .init_array with the GNU extension
     * to pass main() arguments to the init functions. */
    #include <stdlib.h>
    #if defined __GLIBC_PREREQ
    #  if __GLIBC_PREREQ(2, 4)
    /* glibc supports GNU .init_array since 2.4. */
    #  else
    #    error glibc does not support GNU .init_array
    #  endif
    #else
    /*
     * Basic SysV ABI .init_array support, init functions do not get arguments:
     * - Bionic since its inception.
     * - uClibc since 0.9.29.
     */
    #  error unknown whether libc supports GNU .init_array
    #endif

So, it is only happy with a glibc >= 2.4. Unfortunately, uClibc only
impersonates a glibc-2.2, in include/features.h:

      395 #define __GLIBC__   2
      396 #define __GLIBC_MINOR__ 2

I suggest we just disable libbsd (and its reverse dependencies) on
uClibc. Thoughts?

Regards,
Yann E. MORIN.
