I'm trying to create some node.js addons. Inside the addon i have a call to
a static lib. Everything compiles ok, but when i call my addon function
from javascript, i get the following:
* module.js:356*
* Module._extensions[extension](this, filename);*
* ^*
* Error: /home/.../Projects/NodeAddonComLibTest/build/Debug/addon.node:
undefined symbol: _Z6ctest1Pi*
* at Module.load (module.js:356:32)*
* at Function.Module._load (module.js:312:12)*
* at Module.require (module.js:364:17)*
* at require (module.js:380:17)*
* at Object.<anonymous>
(/home/.../Projects/NodeAddonComLibTest/doTest.js:1:75)*
* at Module._compile (module.js:456:26)*
* at Object.Module._extensions..js (module.js:474:10)*
* at Module.load (module.js:356:32)*
* at Function.Module._load (module.js:312:12)*
* at Function.Module.runMain (module.js:497:10)*
My addon code is the following:
* #include <iostream>*
* #include <string.h>*
* #include <stdlib.h>*
*
*
* #include <node.h>*
* #include <v8.h>*
*
*
* using namespace v8;*
* using namespace std;*
*
*
* void ctest1(int *);*
*
*
* Handle<Value> setPort(const Arguments& args){*
* HandleScope scope;*
*
*
* if (args.Length() != 1) {*
* ThrowException(Exception::TypeError(String::New("Wrong number of
arguments.")));*
* return scope.Close(Undefined());*
* }*
*
*
* // =========================*
* printf("Calling static lib...\n");*
* int x=0;*
* ctest1(&x);*
* printf("Val c=%d\n", x);*
* // =========================*
*
*
* return scope.Close(Number::New(args[0]->NumberValue()));*
* }*
*
*
* void Init(Handle<Object> exports) {*
* exports->Set(String::NewSymbol("show"),
FunctionTemplate::New(setPort)->GetFunction());*
* }*
*
*
* NODE_MODULE(addon, Init)*
Can someone help?
Thanks
