Link liboqs statically

[stv0g]

Does liboqs-go support static linking against liboqs?

I would like to build a statically linked Go executable without external depdendencies..

Here is an example as used by go-rosenpass: cunicu/go-rosenpass@fb93e83

@stv0g Thanks, I'll look into it this week

@stv0g The only way to link statically is a bit hacky.

In the cgo preamble of oqs.go, immediately after the line

liboqs-go/oqs/oqs.go

Line 5 in e3e8743

#cgo pkg-config: liboqs

add the line #cgo LDFLAGS: /usr/local/liboqs.a (of course with the path corresponding to your location of liboqs.a). Make sure you don't add any additional new line(s).

Next, comment (add a # in front of) the last line of .config/liboqs.pc (the line starting with Libs:), i.e.,

liboqs-go/.config/liboqs.pc

Line 9 in e3e8743

Libs: -L${LIBOQS_LIB_DIR} -loqs

Finally, do a go clean -cache to force pkg-config to use the updated liboqs.pc.

As far as I know, there's no elegant way of statically linking by only modifying the liboqs.pc file.
