[go-nuts] Re: the size of the files compiled in GO
Please take a look here: https://stackoverflow.com/questions/28576173/reason-for-huge-size-of-compiled-executable-of-go You can probably make it much smaller by just stripping the binary, and for those cases where you want it to be even smaller, you can always use UPX (but that comes with a price in the form of slower startup and higher memory usage).

[go-nuts] Cross compiling with CGO without having a C compiler for each target platform
We are building a system that targets many different combinations of OS's and architectures. Up until now we have been able to keep the whole code base and external packages in pure Go (no CGO), which means that the cross compiler functionality of GC has been sufficient for us. However, recently we have introduced a dependency to an SQLite library (https://github.com/mattn/go-sqlite3) which needs CGO and I want to avoid having each developer to install C compilers for all combinations, so I'm investigating if it would be possible to simplify this process. So let's say I am running Linux/AMD64 on my PC and that my colleague is using a Windows machine. Could I build the CGO part on my machine as an archive file and then ship this archive to my colleagues machine in order to make it possible for him to change GOOS and GOARCH to Linux/AMD64 and thereby enabling him to cross compile (with "go build") for this architecture (without having a C compiler for Linux/AMD64 available)? Is this possible or do we always have to have a C-toolchain available on the machine where we perform the cross compilation?
