Clifford, I tried: https://github.com/csekel/darwinbuild Tag 37 with sudo xcodebuild install DSTROOT=/ ,but the install fails. I built a version of darwinwinbuild if I need to uninstall the version I built were is it? Can I use a whereis like on BSD? I'm getting an error message with Database.cpp. When I built Darwinbuild I had to fix some obsolete functions or methods, It installed but now I'm getting a segmentation fault.

Historically the libc headers have not used availability annotations.

I didn't think about that possibility but it should be doable. Thanks! I still wonder why the function is not declared with weak_import attribute. I have just searched all headers in sys folder and it's not used in any of them. Is there a reason for that (i.e. keeping sys headers free of GNU C extensions)?

connectx() function availability
by Pavol Markovic 17 Mar '17

17 Mar '17

Hello, I'm working on a product statically linking (non-system) libcurl and it is crashing on OS X 10.8 due to missing _connectx symbol in /usr/lib/libSystem.B.dylib Man page shows that: The connectx() function call appeared in Darwin 15.0.0 Why is connectx() function in <sys/socket.h> not marked for weak-linking? As I understand it's recommended to use weak-linking when extending dynamic library (libsystem-kernel.dylib in this case). As a result the libcurl cannot use connectx() fast tcp connect on 10.11 (and later) and at the same time targetting previous systems which do not have this function at all. Any idea how to solve this except of doing preprocessor checks like: #if defined(__MAC_OS_X_VERSION_MIN_REQUIRED) # if (__MAC_OS_X_VERSION_MIN_REQUIRED >= 101100) # define HAVE_DARWIN_CONNECTX 1 # endif #elif defined(__IPHONE_OS_VERSION_MIN_REQUIRED) # if (__IPHONE_OS_VERSION_MIN_REQUIRED >= 90000) # define HAVE_DARWIN_CONNECTX 1 # endif #elif defined(CONNECT_DATA_IDEMPOTENT) /* Fallback for other Darwin OS */ # define HAVE_DARWIN_CONNECTX 1 #endif Best regards, Pavol Markovic _______________________________________________ Do not post admin requests to the list.

Darwin Source Code
by Ethan Sherriff 05 Mar '17

05 Mar '17

Hello, darwin-dev mailing list, I have been experimenting with the darwin sources for quite a while now, and have been making progress with building a couple of key projects, such as dyld and libc (I hope to build a minimal Darwin OS using open source projects released by Apple, and hopefully turn my work into a guide for others to follow). My question is: are there any chances of more open-source darwin projects being released? Currently, there are a lot of projects, such as Libc, which depend on closed-source components like libxpc and its launchd, which would be crucial to make a functioning darwin system. I know that a functioning darwin OS may not feasible anymore, due to availability of source code and/or kernel extensions (and that the open source code which has been released, may just be for people to audit or edit, but not to be used as parts of a standalone operating system), but it would be really great for both Apple and the open-source community if more key projects were released. I know this probably sounds like I’m pleading a bit too much, but if someone could maybe refer this on to somebody at Apple who makes the decisions on which projects become open source, that’d be great. I’m sure that having the sources to projects like libxpc, libsystem_m, would be of a great use to the Darwin open-source community. Thank you for reading this, and thank you Apple for releasing the source code of Darwin :), Ethan _______________________________________________ Do not post admin requests to the list.
