|
|
necessary, because some systems define gettext/textdomain/... in the C
|
|
library (namely, Solaris 2.4 and newer, and GNU libc 2.0 and newer).
|
|
If we used the unprefixed names, there would be cases where the
|
|
definition in the C library would override the one in the libintl.so
|
|
shared library. Recall that on ELF systems, the symbols are looked
|
|
up in the following order:
|
|
1. in the executable,
|
|
2. in the shared libraries specified on the link command line, in order,
|
|
3. in the dependencies of the shared libraries specified on the link
|
|
command line,
|
|
4. in the dlopen()ed shared libraries, in the order in which they were
|
|
dlopen()ed.
|
|
The definition in the C library would override the one in libintl.so if
|
|
either
|
|
* -lc is given on the link command line and -lintl isn't, or
|
|
* -lc is given on the link command line before -lintl, or
|
|
* libintl.so is a dependency of a dlopen()ed shared library but not
|
|
linked to the executable at link time.
|
|
Since Solaris gettext() behaves differently than GNU gettext(), this
|
|
would be unacceptable.
|
|
|
|
The redirection happens by default through macros in C, so that &gettext
|
|
is independent of the compilation unit, but through inline functions in
|
|
C++, in order not to interfere with the name mangling of class fields or
|
|
class methods called 'gettext'. */
