About

This is a minimalistic wrapper for pkg-config that allows to control which libraries should be linked dynamically or statically using two additional environment variables:

• PKG_CONFIG_LIBS_FORCE_STATIC
• PKG_CONFIG_LIBS_FORCE_DYNAMIC

Initially I had to implement this tool to make sure the CGo libraries I have as dependencies for my Android application are linked statically, because otherwise it did not work.

How to use

go install github.com/xaionaro-go/pkg-config-wrapper@latest
PKG_CONFIG_LIBS_FORCE_STATIC="libav*,libvlc" PKG_CONFIG="$(go env GOPATH | awk -F ':' '{print $1}')/bin/pkg-config" go build PATH/TO/MY/PROJECT

It works not only with Go, but also with anything that understands variable PKG_CONFIG.

Example of the output

$ go run ./ --libs-only-l libavcodec
-lavcodec

vs:

$ PKG_CONFIG_LIBS_FORCE_STATIC=libav* go run ./ --libs-only-l libavcodec
