From 01da08fd60a0bdb2994f85f943dba148d9321d4d Mon Sep 17 00:00:00 2001 From: Vadim Kochan Date: Wed, 17 Apr 2019 01:25:40 +0300 Subject: [PATCH 1/1] configure.ac: Properly check for libintl Some libc implementations like uclibc or musl provides gettext stubs via libintl library but this case is not checked by AC_CHECK_LIBRARY(c, gettext ...) because gcc has gettext as builtin which passess the check. So check it with included libintl.h where gettext may unfold into libintl_gettext which will cause check to fail if libintl_gettext are needed to be linked with -lintl.
