[swift-users] Statically linked binaries on linux

[Joel Hughes]

Hello again,

I've been attempting add to the swift-build script so that Foundation can
be compiled as a static lib. Simialr to

> swift/utils/build-script -r --build-swift-static-stdlib --foundation

I'm not familiar with Cmake, ninja and the way the swift is built but have
got the build working. I have a few questions:

Can a libFoundation.a file be compiled from the .o files that are created
while building libFoundation.so?

Is there a guide or recommended tutorial for Cmake and ninja that might be
suitable for a novice, like me?

Are there any documents that give an overview of how the build fits
together and where I should be looking to add functionality? I can't quite
work out how the build script transitions to ninja and clang.

Hope that makes some sense?

Thanks

Joel
