I'm writing a program for both Delphi and Lazarus/FreePascal, so I can also reach customers using Linux or Mac OS X.
Is there a cross-platform tool that works in both environments too, so I can add multiple languages? I tried GNU Gettext for Delphi and C++ Builder, but it does not compile in Lazarus for Mac OS X. Is there anything comparable?
DKLang Localization Package is an open source project that works very well. It has not been tested under FreePascal, but we would be willing assist with any needed changes.
No, simply since the only system that FPC uses is gettext. Lazarus afaik uses gettext, also on OS X, but obviously the FPC one, not the delphi one.
I suggest you devote some more attention to getting the gettext solution to work, maybe asking specific questions here.
In reply to your comment:
If I look in the LCL, I see in the translate routines stuff that translates properties of tpersistents, but only for special "TTranslatestrings" fields. So it doesn't seem to translate full forms directly.
Did you have a look at this:? http://wiki.lazarus.freepascal.org/DxGetText
