I was writing C++ Addon for Node.js. Tried to use sample library called libSample.so which has declaration of function printHello:
void printHello() {
std::cout << "Hello World\n";
}
It worked fine.(Compiled using node-gyp configure build
and executed node ./
)
When I tried to use another more complex library called libCore.so. The following error produced when started to execute. Compilation and configure passed find:
module.js:597
return process.dlopen(module, path._makeLong(filename));
^
Error: libPlayerCore.so: cannot open shared object file: No such file or directory

some piece of usage libCore.so
//#include <core.h> definition of core library lies in this header
void CreateObject(const FunctionCallbackInfo<Value>& args) {
Isolate* isolate = args.GetIsolate();
Local<Object> obj = Object::New(isolate);
obj->Set(String::NewFromUtf8(isolate, "msg"), args[0]->ToString());
//usage of core library
Core core;
args.GetReturnValue().Set(obj);
}
The binding.gyp file: the path is correct, because it is worked with another library :)
{
"targets": [
{
"target_name": "addon",
"sources": [ "hello.cc" ],
"libraries": [
"/home/jasurn/CLionProjects/JsTest/libPlayerCore/lib/libCore.so"
]
}
]
}
I will be appreciated for answers or suggestions!
Found simple solution, but i maybe not okay for long-development. I think problem was with dependency libraries needed for your shared library. You can see needed libraries by command on terminal lld libCore.so
linux-vdso.so.1 => (0x00007ffcae9d6000)
libasound.so.2 => /usr/lib/x86_64-linux-gnu/libasound.so.2 (0x00007fa19dc07000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa19d9e9000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fa19d7e5000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fa19d45c000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fa19d153000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fa19cf3a000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa19cb73000)
/lib64/ld-linux-x86-64.so.2 (0x00005637d3532000)
librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fa19c96b000)
Above the list of dependent libraries for my shared library.
SOLUTION:
You should copy your shared library to /usr/lib location. This way solved my problem.
cp path/where/yourLocated/libCore.so /usr/lib
