| 0 | 1 Notes on GCC's Native Language Support |
| 2 | |
| 3 By and large, only diagnostic messages have been internationalized. | |
| 4 Some work remains in other areas; for example, GCC does not yet allow | |
| 5 non-ASCII letters in identifiers. | |
| 6 | |
| 7 Not all of GCC's diagnostic messages have been internationalized. Programs | |
| 8 like `genattr' (in fact all gen* programs) are not internationalized, as | |
| 9 their users are GCC maintainers who typically need to be able to read | |
| 10 English anyway; internationalizing them would thus entail needless work for | |
| 11 the human translators. Messages used for debugging, such as used in dumped | |
| 12 tables, should also not be translated. | |
| 13 | |
| 14 The GCC library should not contain any messages that need | |
| 15 internationalization, because it operates below the internationalization | |
| 16 library. | |
| 17 | |
| 18 Unlike some other GNU programs, the GCC sources contain few instances | |
| 19 of explicit translation calls like _("string"). Instead, the | |
| 20 diagnostic printing routines automatically translate their arguments. | |
| 21 For example, GCC source code should not contain calls like `error | |
| 22 (_("unterminated comment"))'; it should contain calls like `error | |
| 23 ("unterminated comment")' instead, as it is the `error' function's | |
| 24 responsibility to translate the message before the user sees it. | |
| 25 | |
| 26 By convention, any function parameter in the GCC sources whose name | |
| 27 ends in `msgid' is expected to be a message requiring translation. | |
| 28 If the parameter name ends with `gmsgid', it is assumed to be a GCC | |
| 29 diagnostics format string requiring translation, if it ends with | |
| 30 `cmsgid', it is assumed to be a format string for `printf' family | |
| 31 of functions, requiring a translation. | |
| 32 For example, the `error' function's first parameter is named `gmsgid'. | |
| 33 GCC's exgettext script uses this convention to determine which | |
| 34 function parameter strings need to be translated. The exgettext | |
| 35 script also assumes that any occurrence of `%eMSGID}' on a source | |
| 36 line, where MSGID does not contain `%' or `}', corresponds to a | |
| 37 message MSGID that requires translation; this is needed to identify | |
| 38 diagnostics in GCC spec strings. | |
| 39 The `G_(GMSGID)' macro defined in intl.h can be used to mark GCC diagnostics | |
| 40 format strings as requiring translation, but other than that it is a | |
| 41 no-op at runtime. | |
| 42 | |
| 43 If you modify source files, you'll need at least version 0.14.15 of the | |
| 44 GNU gettext package to propagate the modifications to the translation | |
| 45 tables. | |
| 46 | |
| 47 After having built and installed these gettext tools, you have to | |
| 48 configure GCC with --enable-maintainer-mode to get the master catalog | |
| 49 rebuilt. | |
