nls 编译过程 The Complicated Way

The Complicated Way
This approach is for those who have a PostgreSQL development source tree and all the gettext utilities. In that case you can skip the extra downloads.

$ ./configure --enable-nls
Make sure you have the required software tools.
Decide for which component you want to translate the messages. Change to that directory (e.g., src/bin/psql).
If there is no nls.mk file there, this component has not been prepared for NLS. Go back to 2.
$ ls po/*.po
If this matches one of the languages you want to work on, skip ahead to 8.
$ gmake init-po
$ cp po/COMPONENT.pot po/LL.po
(COMPONENT will be obvious, as there will be only one .pot file. LL is the code of your language.)
Add LL to AVAIL_LANGUAGES in nls.mk (in alphabetical order, please).
Edit the comments at the top of the .po file. Then go to 9.
$ gmake update-po LANGUAGES=LL
This will merge the existing translations with any new messages that might be in the program sources. It will also create a backup of the LL.po file named LL.po.old, which you need to keep around to create a patch later on. You could also
$ cp po/LL.po po/LL.po.old
at this point to create the backup file only.
Edit the .po file. (I.e., do the translation work.)
Repeat 9 to exhaustion.
$ gmake maintainer-check
Fix any errors this might point out. (If you use the Emacs PO mode, press V on occasion, it does the same thing.)
If you made significant changes, add your name to the top of the file, below any other names.
Send the new PO file to [e-mail]. Also make sure the nls.mk file gets changed appropriately. Please do not send a patch for the PO file or put the PO file in an archive with other files. That creates unnecessary work for the person installing your file.
Go to step 2.
