Not all Darwin projects have been tested, but several commonly built projects such as xnu and cctools can be compiled in the chroot environment. Please report any problems via the DarwinBuild Trac database <http://trac.macosforge.org/projects/darwinbuild >.

When you type `open(...)` in your C code, one of those symbol names is chosen depending on your compile options (specifically UNIX compliance, in this case). You can use `nm -m` on your app to see which version it's linking to. For example, a trivial 32-bit i386 test program built on Leopard with `cc` and no other options uses _open$UNIX2003. Good point. Be sure to include the appropriate header files so that you get the $UNIX2003 magic. Relying on implicit function declarations will not work.

Does anything changed about dyld in Leopard? :| I'm not sure whether it's a Leopard change or not, but I believe that DYLD_INSERT_LIBRARIES is ignored if the target binary is setuid. I also notice you're only compiling with -arch ppc; is it possible the target binary is compiled for a different architecture (i.e. ppc64?). This email sent to site_archiver(a)lists.apple.com

What file system are we talking about? When you say "list", do you mean ls(1) ? Why is the same name listed twice? A shot in the dark would be to adjust the encoding of your terminal, but without knowing what exactly you do, nobody will be able to say much Hello! I need to migrate a Linux backup solution to Mac. When we list dir trees, some file names as "José Lopes.txt" appear as "Jose?? L??opes.txt?. These are listed also as "Jose\314\201 ..." Some help ?

Is there an easier way? Add "-v" to the command that does the linking (be it gcc or collect2), then you'll see how ld is called exactly. This email sent to site_archiver(a)lists.apple.com
