4.1 Importing the gettext declaration
Presuming that your set of programs, or package, has been adjusted so all needed GNU gettext
files are available, and your Makefile
files are adjusted (see Maintainers), each C module having translated C strings should contain the line:
#include <libintl.h>
Similarly, each C module containing printf()
/fprintf()
/... calls with a format string that could be a translated C string (even if the C string comes from a different C module) should contain the line:
#include <libintl.h>
