Hello. I initially posted this message to the darwin-kernel list, but after contacting DTS in the hopes they might support this code base, they pointed me here which is apparently the correct place for this message. Ultimately, I would like to be able to build the latest released version of dyld ( http://opensource.apple.com/tarballs/dyld/dyld-239.4.tar.gz ). If I understand correctly, in order to do that I need to be able to build Libc and am attempting to build the latest released version ( http://opensource.apple.com/tarballs/Libc/Libc-997.90.3.tar.gz ). By following the instructions at http://shantonu.blogspot.com/2013/10/building-xnu-for-os-x-109-mavericks.htm..., I was able to get the latest released version of the xnu source built ( http://opensource.apple.com/tarballs/xnu/xnu-2422.90.20.tar.gz ) - well, I did need to take into account one of the comments and removed the -Werror flag. Additionally, I did run ‘make install’ to get the BUILD/dst folder. Just opening the Libc, Xcode project and trying to build it, gives me one error: Libc-997.90.3/string/bcopy.c:24:10: 'platform/string.h' file not found Looking through the built XNU source, I do see string.h, but not within a platform folder. While I can take a guess at which string.h is the intended one and either alter the #include or create a platform folder and place string.h inside of it while updating the header search paths, I would much rather try to figure out what the proper way to get this all to build is. Additionally, while attempting to build, I was coming across files like _simple.h, asl_private.h, the pthreads folder, etc. which existed in older versions of Libc, but not in the most recent released version. Is there a reason for this? Is it valid to just take the header files from the older version of Libc? If anyone had any advice or pointers to blog posts which provide a good set of instructions, I would be interested. Thank you. _______________________________________________ Do not post admin requests to the list. They will be ignored.
