Re: Use 0compile to link against native binary for lib

This has the same effect. I am confused by this, I don’t have MacPorts installed, so I though using the MacPorts distribution support would be incorrect. I don’t even know if package-implementations are even the right approach here?

What I am trying to accomplish is to statically link against native zlib on platforms where it is available, and install it on platforms where it isn’t. On Mac OS X it is available, I don’t need any package manager to install it, unless I’d need a different version. On Windows I’d have to install zlib. How would I express this in a feed file?

Thanks for you help, and apologies if I seem to be slow to grasp this.

Cheers,

	Björn
