Dependencies for this library are fairly complicated and +therefore, deserves some explanation. + +The 'uClibc' C library doesn't implement gettext functionality, +therefore with this C library, a separate gettext must be compiled. On +the other hand, the 'glibc' C library does integrate its own gettext, +and in this case, the separate gettext library should not be compiled, +because it creates various kinds of build failures. + +Additionally, some packages (such as +libglib2+) do require gettext +unconditionally, while other packages (those who support ++--disable-nls+ in general) only require gettext when locale support +is enabled. + +Therefore, Buildroot defines two configuration options: + +* +BR2_NEEDS_GETTEXT+, which is true as soon as the toolchain doesn't + provide its own gettext implementation + +* +BR2_NEEDS_GETTEXT_IF_LOCALE+, which is true if the toolchain + doesn't provide its own gettext implementation and if locale support + is enabled + +Therefore, packages that unconditionally need gettext should: + +* Use +select BR2_PACKAGE_GETTEXT if BR2_NEEDS_GETTEXT+ and possibly + +select BR2_PACKAGE_LIBINTL if BR2_NEEDS_GETTEXT+, if libintl is + also needed + +* Use +$(if $(BR2_NEEDS_GETTEXT),gettext)+ in the package + +DEPENDENCIES+ variable + +Packages that need gettext only when locale support is enabled should: + +* Use +select BR2_PACKAGE_GETTEXT if BR2_NEEDS_GETTEXT_IF_LOCALE+ and + possibly +select BR2_PACKAGE_LIBINTL if + BR2_NEEDS_GETTEXT_IF_LOCALE+, if libintl is also needed + +* Use +$(if $(BR2_NEEDS_GETTEXT_IF_LOCALE),gettext)+ in the package + +DEPENDENCIES+ variable |
