28 /* This file redirects the gettext functions (without prefix or suffix) to
29 those defined in the included GNU gettext library (with "__" suffix).
30 It is compiled into libintl when the included GNU gettext library is
31 configured --with-included-gettext.
33 This redirection works also in the case that the system C library or
34 the system libintl library contain gettext/textdomain/... functions.
35 If it didn't, we would need to add preprocessor level redirections to
36 libgnuintl.h of the following form:
38 # define gettext gettext__
39 # define dgettext dgettext__
40 # define dcgettext dcgettext__
41 # define ngettext ngettext__
42 # define dngettext dngettext__
43 # define dcngettext dcngettext__
44 # define textdomain textdomain__
45 # define bindtextdomain bindtextdomain__
46 # define bind_textdomain_codeset bind_textdomain_codeset__
48 How does this redirection work? There are two cases.
49 A. When libintl.a is linked into an executable, it works because
50 functions defined in the executable always override functions in
52 B. When libintl.so is used, it works because
53 1. those systems defining gettext/textdomain/... in the C library
54 (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer) are
55 ELF systems and define these symbols as weak, thus explicitly
56 letting other shared libraries override it.
57 2. those systems defining gettext/textdomain/... in a standalone
58 libintl.so library (namely, Solaris 2.3 and newer) have this
59 shared library in /usr/lib, and the linker will search /usr/lib
60 *after* the directory where the GNU gettext library is installed.
62 A third case, namely when libintl.a is linked into a shared library
63 whose name is not libintl.so, is not supported. In this case, on
64 Solaris, when -lintl precedes the linker option for the shared library
65 containing GNU gettext, the system's gettext would indeed override
66 the GNU gettext. Anyone doing this kind of stuff must be clever enough
67 to 1. compile libintl.a with -fPIC, 2. remove -lintl from his linker
