Hello, I need to compile postfix and OpenLDAP for Darwin, I tried to follow all the guidelines in DarwinBuild Readme file and on google but when I try to compile those projects I get many errors: I am building for darwin version 9F33 I did for X in `darwinxref version '*'` ; do darwinbuild -load ${X/-*/} ; done to load all dependencies and available binaries as root of course then I did as a test darwinbuild CF but that give me the following error ForFoundationOnly.h:170:49: error: CoreFoundation/ CFNotificationCenter.h: No such file or directory I tried darwinbuild postfix but I got the error file /usr/lib/libauto.dylib not found I finally managed to build postfix using the option -nochroot, but still don't know why the previous command did not work I tried darwinbuild OpenLDAP but the file pac.h and libpac.dylib are missing, I searched every darwin packages but couldn't find it, I tried to remove the -lpac from the Makefile, but the error only comes later : pac.h no such file or directory If someone could help me resolve these problems that would great ? Maybe I am missing something in the way I use darwinbuild ! Regards, Numa
