[PATCH] kconfig: detect if -lintl is needed when linking conf,mconf

5e375bc7 · Robb, Sam <[email protected]> · 2006-02-04 23:28:06 -08:00

On a system where libintl.h is present, but the NLS functionality is
supplied by a separate library instead of the system C library, an attempt
to "make config" or "make menuconfig" will fail with link errors, ex:

  scripts/kconfig/mconf.o:mconf.c:(.text+0xf63): undefined reference to
    `_libintl_gettext'

This patch attempts to correct the problem by detecting whether or not NLS
support requires linking with libintl.
