undefined reference linking errors during cross-compilation (using cmake-js)

Hello,

In order to demonstrate this issue, I used this example https://github.com/nodejs/node-addon-examples/tree/main/build_with_cmake/node-addon-api.

After running npm installtion (cmake-js was globally installed), I was able to successfully create node modules for the linux with just a cmake-js compile. I then attempted a cross-compilation for Windows using mingw-w64 (x86_64-w64-mingw32-g++ (GCC) 8.3-posix 20190406 - used the non-default posix since std::mutex used by napi was not supported by the default cross-compiler).

cmake-js compile --CDCMAKE_CXX_COMPILER="/usr/bin/x86_64-w64-mingw32-g++"

However, I get the following output which states that compilation failed due to a lot of undefined references at the linking step.

Thank you for any help.

Hi @sakthi-vivek,
based on my experience whan you compile using mingw you will always obtain linker error like you reported. The problem is that you cannot use the flags -Wl,-unresolved-symbols=ignore-all (Linux) or -Wl,-undefined,dynamic_lookup (macOS), but you need to specify all the symblos you will use to do that you can use a library stub for the symbls exported by Node-API.

In some projects I used the library stub of Node-API that you can downlod from here: https://github.com/napi-bindings/node-api-stub/releases

The CMake file that I sued is like the following:

cmake_minimum_required(VERSION 3.16)
cmake_policy(SET CMP0042 NEW)
project(addon)

set(CMAKE_CXX_STANDARD 11)

set(CMAKE_NODE_API_LIB libnode.a)

include_directories(${CMAKE_SOURCE_DIR}/include)

set(SOURCE_FILES
        ${CMAKE_CURRENT_SOURCE_DIR}/addon.cc
        )

add_library(${PROJECT_NAME} SHARED ${SOURCE_FILES})
set_target_properties(${PROJECT_NAME} PROPERTIES PREFIX "" SUFFIX ".node")
target_link_libraries(${PROJECT_NAME} ${CMAKE_SOURCE_DIR}/lib/${CMAKE_NODE_API_LIB})


# Define NAPI_VERSION
add_definitions(-DNAPI_VERSION=3)

I put the library stub in the lib folder and the include Node-API header files in the include folder. You can find the Node-API headers file in this repo: https://github.com/nodejs/node-api-headers.

In my case I compiled and built the addon directly from WIndows using the following command:

cmake.exe -DCMAKE_BUILD_TYPE=Debug -DCMAKE_MAKE_PROGRAM=C:/TDM-GCC-64/bin/mingw32-make.exe -DCMAKE_C_COMPILER=C:/TDM-GCC-64/bin/gcc.exe -DCMAKE_CXX_COMPILER=C:/TDM-GCC-64/bin/g++.exe -G "CodeBlocks - MinGW Makefiles"

I hope that the these info could help you.

@NickNaso

@NickNaso Thank you for the reply. I managed to cross-compile for Windows from Linux, thanks to your node-api-stub. However I am getting a not a Win32 application error when I run the module in windows. Maybe it is a different issue and I would do a search for if someone had faced similar issues, and how they solved it.

I am closing this issue, but could you please share any tips that we should be aware of when we are using the stub library? For more context, I am using the resultant node artifact in an electron application.

Thank you again for the help :)

@sakthi-vivek

Hi @sakthi-vivek,
I will try to read an artile for the stub and in the past I also met your problem and I well remenber is in how to you export your addon when you are on windows you should use __declspec(dllexport) like reported in the example below:

#include <node_api.h>
#include "addon.h"
extern "C" {

extern __declspec(dllexport)  napi_value napi_register_module_v1(napi_env env, napi_value exports) {
    return  Initialize(env, exports);
}
 
}

I hope that this works for you.

@NickNaso

Thank you @NickNaso,

May I ask where exactly is addon.h present ? I am using node-addon-api v3.1.0.

I have also discovered that the cmake-js doesn't support MinGW compilation cmake-js/cmake-js#195. This is unfortunate and now I am left with the choice of MSVC for windows compilation and a solution like https://github.com/mstorsjo/msvc-wine for cross-compilation from linux.

@sakthi-vivek

Hi @sakthi-vivek,
addon.h contains my code nothing particular. Yes you're right cmake-js doesn't support MinGW and this pushed to me to create my workaround to build the addon. I hope to use my knowledge to create a tool to build the addon using Node-API. Another correlated issue is nodejs/node#38782.
