The other question is if I want to put a lot of time into that one, I only wanted to see if it works - according to the source it must have been working with fpc once. I'll see if the author is still working on this or the successor of it and decide after that.

That's a Kylix legacy unit. It means that this package was never fully converted to FPC. It only exists for linux/x86 with a glibc.

That's because they are temporary workarounds for the older linux architectures when they made a 32-bit -> 64-bit off_t transition.

Replace -64 functions by their plain equivalents. (FreeBSD 4+ already has 64-bit off_t) And hope that they didn't use too exotic functions from unit libc. If so, report here. In 2.2.2 some routines to access users/passwords were added, maybe you can take the sources from there (packages/users), and try to get it running under 2.0.4 ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

You should try to find out why unit libc is used. Michael. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
