a question about how/where a fresh lucky project use libgmp?

[zw963]

Things happen like this, i use zig cc for linking a static binary in my Arch linux and copy to server for deployment.
It need copy needed alpine static library in somewhere and let zig cc know where it to linking, so, the versions of those library are involved.

there is a project named(magic-haversack) make download those alpine static library easy, i have my own folk,
it work quite well and use it daily, all things is good for now.

Then, the original author update many library to newest version yesterday, i tried it immediately, but no luck, it works on those apps fewer depndencies, but for a lucky project, i get error like this:

zig cc -target x86_64-linux-musl /test_lucky.o -o /test_lucky -s -rdynamic -static -L/home/zw963/Crystal/new_static_libraries/x86_64-linux-musl -lgmp -lyaml -lz `command -v pkg-config > /dev/null && pkg-config --libs --silence-errors libssl || printf %s '-lssl -lcrypto'` `command -v pkg-config > /dev/null && pkg-config --libs --silence-errors libcrypto || printf %s '-lcrypto'` -lpcre2-8 -lgc -lpthread -ldl -levent -lunwind

LLD Link... ld.lld: error: undefined symbol: __gmp_set_memory_functions
>>> referenced by main_module
>>>               /test_lucky.o:(__crystal_main)

I can reproduce it with a fresh new 1.1.1 lucky app.

the original author never use lucky, so, i ask question here for help, if we can give some clue to him, that will help a lot.

For the one interesting the process, please check following links:

how to use zig as linker

my fork

You can always check the library version use libs.yml in the project root. e.g.

Thank you, the original author find the reason.

libgmp used by BigInt, can be reproduced use following script

# 1.cr
require "big"

p! BigInt.new
