Can someone explain to me how to use the oscpack library in an Eclipse workspace based project? I have created the object files with make, added the ip and osc directories to my project tree, and added these directories to the include path list in Project settings>C/C++ Build>Settings>GCC C++ Compiler>Includes.
I haven't been able to get it working in Eclipse or the g++ commandline compiler. I am running out of ideas.
The code is the SimpleReceive.cpp from the oscpack site btw.
/*
Example of two different ways to process received OSC messages using oscpack.
Receives the messages from the SimpleSend.cpp example.
*/
#include <iostream>
#include "osc/OscReceivedElements.h"
#include "osc/OscPacketListener.h"
#include "ip/UdpSocket.h"
#define PORT 7000
class ExamplePacketListener : public osc::OscPacketListener {
protected:
virtual void ProcessMessage( const osc::ReceivedMessage& m,
const IpEndpointName& remoteEndpoint )
{
try{
// example of parsing single messages. osc::OsckPacketListener
// handles the bundle traversal.
if( strcmp( m.AddressPattern(), "/test1" ) == 0 ){
// example #1 -- argument stream interface
osc::ReceivedMessageArgumentStream args = m.ArgumentStream();
bool a1;
osc::int32 a2;
float a3;
const char *a4;
args >> a1 >> a2 >> a3 >> a4 >> osc::EndMessage;
std::cout << "received '/test1' message with arguments: "
<< a1 << " " << a2 << " " << a3 << " " << a4 << "\n";
}else if( strcmp( m.AddressPattern(), "/test2" ) == 0 ){
// example #2 -- argument iterator interface, supports
// reflection for overloaded messages (eg you can call
// (*arg)->IsBool() to check if a bool was passed etc).
osc::ReceivedMessage::const_iterator arg = m.ArgumentsBegin();
bool a1 = (arg++)->AsBool();
int a2 = (arg++)->AsInt32();
float a3 = (arg++)->AsFloat();
const char *a4 = (arg++)->AsString();
if( arg != m.ArgumentsEnd() )
throw osc::ExcessArgumentException();
std::cout << "received '/test2' message with arguments: "
<< a1 << " " << a2 << " " << a3 << " " << a4 << "\n";
}
}catch( osc::Exception& e ){
// any parsing errors such as unexpected argument types, or
// missing arguments get thrown as exceptions.
std::cout << "error while parsing message: "
<< m.AddressPattern() << ": " << e.what() << "\n";
}
}
};
int main(int argc, char* argv[])
{
ExamplePacketListener listener;
UdpListeningReceiveSocket s(
IpEndpointName( IpEndpointName::ANY_ADDRESS, PORT ),
&listener );
std::cout << "press ctrl-c to end\n";
s.RunUntilSigInt();
return 0;
}

So you needed to configure the paths and compiler/linker options.
On my ubuntu box, after apt-get install liboscpack-dev it compiled fine using the following options:
g++ -Wall -pedantic -g -O0 -I /usr/include/oscpack test.cpp -o test -loscpack
On your box you might need to add the path to the library too, e.g.
-L /usr/local/lib/oscpack
(I did add #include <cstring> that was missing, though)
