digitalmars.D.learn - Using phobos as shared library for multiple binaries

reply Ralf <ralf nowhere.com> writes:
Hi,

I've written several small command-line utilities in D that are 
to be shipped together in one package. Each one of them only 
would be only a few kB in size, but they end up being ~1Mb, I 
assume because every one links statically parts of the standard 
library.

How can this be improved?

Are there binary builds of the standard library (for OS X) 
somewhere and an option to tell the compiler to link to this 
shared library?

Alternatively, is there a way to build a shared library that all 
the binaries can use together so they can share the common code?

Greetings,

Ralf

I'm not sure if shared lib support is on Mac or not (I know it is 
on Linux but mac is different...).

But do they need to actually be separate executables? You could 
make them all one program and switch(args[0]) {} to see which 
name it was called by. Symlink all the various names to the one 
executable and the user will never know.

Some links for you:
http://dlang.org/dmd-osx.html   Check -defaultlib

http://dlang.org/dll-linux.html    This is for Linux, but check 
the last code example. It can help. I did what you ask in Linux, 
it works, but don't have knowledge about OS X.
