libzim.so.9.4.0 is missing zim::validate symbol in archive on openzim.org

Release on openzim is missing zim::validate
Url: https://download.openzim.org/release/libzim/libzim_linux-x86_64-9.4.0.tar.gz

When trying to build node-libzim (this is issue is related to this projects release on openzim) I get the following error.

node: symbol lookup error: ./node-libzim/build/Debug/zim_binding.node: undefined symbol: _ZN3zim8validateERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESt6bitsetILm7EE

I've validated the library I get is the one from openzim
I tried it with another binary and it still fails.

./test-validate: symbol lookup error: ./test-validate: undefined symbol: _ZN3zim8validateERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESt6bitsetILm7EE

Code to reproduce

#include <iostream>
#include <string>
#include "zim/archive.h"

int main() {
  std::string path = "./test-read.zim";
  zim::IntegrityCheckList checksToRun;
  checksToRun.set(static_cast<size_t>(zim::IntegrityCheck::CHECKSUM));
  std::cout << "Running checks: " << zim::validate(path, checksToRun)
            << std::endl;
  return 0;
}

Compile with g++ -o test-validate -I./download/include/ ./download/lib/x86_64-linux-gnu/libzim.so.9.4.0 ./test.cc

The symbol is obviously there:

$ nm -CD libzim_linux-x86_64-9.4.0/lib/x86_64-linux-gnu/libzim.so|grep zim::validate
00000000001f1840 T zim::validate(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::bitset<7ul>)

The problem is with the order of arguments. The following command should succeed:

g++ -o test-validate -I./download/include/ ./test.cc ./download/lib/x86_64-linux-gnu/libzim.so.9.4.0

g++ -o test-validate -I./download/include/ ./test.cc ./download/lib/x86_64-linux-gnu/libzim.so.9.4.0 && ./test-validate

./test-validate: symbol lookup error: ./test-validate: undefined symbol: _ZN3zim8validateERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEESt6bitsetILm7EE

Turns out I needed export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD/download/lib/x86_64-linux-gnu/
I had forgotten the binary was looking for a shared library ;D

@kelvinhammond Thanks for your comment. I had overlooked that your real problem was about a runtime error rather than a build error that I ran into while investigating this issue.

@kelson42 Why did you reopen the ticket? There was no problem with libzim. The author of the ticket simply provided additional clarifications about what was wrong about their setup.
