Hello DarwinBuild developers, I have a problem when trying to build dynamic loader. Apple Developer Tech Support suggested posting it as an inquiry to the DarwinBuild developers mailing list. I would appreciate any assistance or advice. Here are the details: I'm trying to build dyld-195.5. http://opensource.apple.com/release/mac-os-x-1072/ It looks like I am missing some files, at least: ${SDKROOT}/usr/local/lib/dyld/*.a files. I have both MacOSX10.6.sdk & MacOSX10.7.sdk installed in the /Developer/SDKs Where can I get the right SDK? I've tried to build libc-dyld.a from sources. I've built xnu-1699.24.8 but was having troubles with Libc-763.12 Error occurs: macros __DARWIN_ALIAS_STARTING_MAC_xx are undefined. If define them as empty another errors occur: $ make build /bin/mkdir -p -m 0755 /Users/diman/prog/Libc-763.12/OBJROOT/obj.i386 && MAKEOBJDIR="/Users/diman/prog/Libc-763.12/OBJROOT/obj.i386" MACHINE_ARCH=i386 CCARCH=i386 DSTROOT=/ OBJROOT=/Users/diman/prog/Libc-763.12/OBJROOT SYMROOT=/Users/diman/prog/Libc-763.12/SYMROOT RC_NONARCH_CFLAGS="-pipe" MAKEFLAGS="" OBJSUFFIX="o" /Developer/usr/bin/bsdmake -f Makefile -j 6 libc_static.a building static c library /usr/bin/nm: no name list /usr/bin/nm: can't open file: CANCELABLE/creat-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/sigcompat-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/lockf-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/nanosleep-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/pause-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/pselect-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/sleep-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/termios-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/usleep-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/wait-CANCELABLE.o (No such file or directory) /usr/bin/nm: can't open file: CANCELABLE/waitpid-CANCELABLE.o (No such file or directory) Is any Libc building "how to" available? --------------------------------- Thank you, Anatoly Fedorovsky
