Hi,

I need to build the library so that I can use the following functions: crypto_sign_keypair(), crypto_sign_detached() and crypto_sign_verify_detached()

is it possible?

thanks.

Nope, but you already have a fantastic tool to only import the functions an application needs from a library: the linker :)

yes, it's a super utility! but my question is related to the fact I need to be able to build a small program that uses libsodium as quickly as possible, every time a user runs some script...

LTO (the modern way to get rid off unwanted symbols) is not recommended for libsodium, but the old way (function-sections) might work (but is, I assume, wholly unsupported). This of course requires to build libsodium as a static library.
