zip_open_from_source() & zip_source_buffer_create() not defined in libzip_all.c

[byt3bl33d3r]

Heya,

I'm trying to get this library working when cross-compiling to Windows using the MingW toolchain, this is the Nim code i'm using:

import zip/zipfiles
import strformat
import os

const
    pyzip = slurp"../rsrc/python-3.9.1-embed-amd64.zip"
    tmpdir: string = getEnv("LOCALAPPDATA") / "Temp"

proc extractPython(): bool =
    var z: ZipArchive
    z.fromBuffer(pyzip)
    z.extractAll(tmpdir)
    return true

proc main(): void =
    echo fmt"[*] tmpdir: {tmpdir}"
    if extractPython():
        echo fmt"[*] Python extracted"

when isMainModule:
    main()

I compiled zlib v1.2.11 and made it available to MingW using the instructions from here & here

I then ran the following command to cross-compile the above Nim code and point the linker and compiler to the zlib directory:

nim c -d=useLibzipSrc -d=debug -d=mingw --embedsrc=on --hints=on --app=console --cpu=amd64 --passL:"-L/home/byt3bl33d3r/Devel/zlib-1.2.11 -lzlib1" --passC:"-I/home/byt3bl33d3r/Devel/zlib-1.2.11" --out=bin/embed_rsrc_bin_64.exe src/embed_rsrc_bin.nim

This gives the following error when compiled:

After some investigation libzip.nim has those two functions defined however they're not actually in the libzip_all.c file. It seems like those two functions are only available in libzip starting from version >= 1.0 (the current libzip_all.c file seems to be based off of libzip 0.9?).

I'm not sure If i'm doing something wrong here, but I think that's the problem.

Thanks.
