I have kept plist file in launchAgents folder. Now, if I quit daemon then it will be killed and to launch it again, I should know the path where I kept it. I want to stop and restart the daemon whenever I need requires without knowing the path of damon. How can I do it? It is ok if I have to do from terminal. I think, it is possible using the writing script to stop and start, but I do not require that thing. Please advice me. Thanks in advance.

The output of my environment is perfectly fine and sufficient for my purposes. I don't understand what the ruckus is all about. The environment already generates the ELF format without using a linker. When and if the Mach-O format changes, I will fix my code. Until then it works, does not and will not use a linker. There's no point in trying to convince me otherwise. This email sent to site_archiver(a)lists.apple.com

Because I'm generating Mac binaries and the Mach- O headers on Linux. It's called cross-compilation and is the only option I have to bring up a development environment on my Mac.

[...] PS: I'm also still not seeing why you don't want to be able to link your compiler's output with third party supplied libraries. Because that's not how Forth works, at least not this Forth. I can use any libraries by dynamically loading them into the running image. At least I think I can with the Mach-O logic I'm using currently. If my generated Mach-O does not support it then I'll need to modify my logic. This email sent to site_archiver(a)lists.apple.com
