Zero dependency binary #102

Open sachin-walia opened 8 years ago

sachin-walia commented 8 years ago

I don't have lot of understanding of go packaging so please don't mind if question sounds too basic.

Is it possible to package the binary in such a way that all the required dependencies (libpng, libvips, pango and others) are included in a single executable file?

There are some articles about building go apps with statically linked libraries:

I tried with both of them without success.

I'm not sure if it's even possible due to the licenses of the various linked libraries. If you want an easily distributable "package" I recommend using the Docker image.

kirillDanshin commented 7 years ago

it's possible, just distribute 3rd-party licenses with (or in) your package
