That's why the last time I did this kind of port I have developped a posix emulation layer. I have implemented all posix functions, getenv, open, create, .... with file api based on fopen because from a FILE* it's possible to get the underlying file descriptor (bot not the opposite) and I was maintening an array mapping filedescriptor and FILE*. Now I know that usually open source project on windows CE use HANDLE as a filedescriptor. Unfortunately this year I was supposed to finish a dll implementing all this posix functions and include it in the software we provide to HTC. It would have allowed to close all this issues about missing posix functions. But I still think that you should email linpng, zlib , ... mainteners to tell them that if they plan to release a new version they should replace all posix functions by what you suggest (a wrapper that could be then implemented using OS specific). Vincent, I suppose you don't have time to do it but what about creating a project let's call it posix4ce that would implement a DLL with posix functions it would help projects to access windows ce device more easily. This is something I am dreaming for about 4 years and I think it's something I have mentioned in my first post on this ML. To finish with this subject, when I look at open source projects, I can see that each one is always reimplementing the same thing and I find it fucking stupid because one dll could have changed that. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Cegcc-devel mailing list Cegcc-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/cegcc-devel
