C has an eco-system? Really? Yeah, sure I can download source code and headers and somehow use 12 different antiquated tools that strung together with duck tape and bubble gum that are also not standard on Windows let's say, to actually hopefully compile that code, and then worry about 12 other different tools each with 6 different options to be able to do something simple like "link a library", and hope that works on FreeBSD and OS X and Windows, but it won't, it never does, without spending an insane amount of time tweaking headers and m4 macros, before giving up and learning CMake, but if that's what you consider a "mature eco-system", then you have very low standards.

No one doubts that there is a rich ecosystem available for C. The thing just is, when you are working in a Go environment, what benefit would adding C with its own toolchain bring?

Not the build system, a pain to get the libraries in Windows for a Multiplatform project that I wanna compile.

Where in Go this is very easy
