• Follow the tutorial until have OpenFrameworks and Addons in your projects.

Import the generated project as “Existing code as makefile project”. You only need to add OpenFrameworks and Addons projects as references in your new project (do not forget to select “Linux GCC”).

• To add an addon after having created the project you just need to include its name in the addons.make file.
• To compile with C++11 you need to go to libs/openFrameworksCompiled/project/makefileCommon path and edit the main makefile which is compile.project.mk. You need to search for the rule that does the compilation and add: -std=c++0x.

$(OF_PROJECT_OBJ_OUPUT_PATH)%.o: $(PROJECT_ROOT)/%.cpp
	@echo "Compiling" $<
	@mkdir -p $(@D)
	$(CXX) -c $(OPTIMIZATION_CFLAGS) $(CFLAGS) $(CXXFLAGS) -std=c++0x -MMD -MP -MF $(OF_PROJECT_OBJ_OUPUT_PATH)$*.d -MT $(OF_PROJECT_OBJ_OUPUT_PATH)$*.o -o $@ -c $<

• Muy probablemente quieras usar otras libs, las tendrías que añadir también en el makefile:

$(TARGET): $(OF_PROJECT_OBJS) $(OF_PROJECT_ADDONS_OBJS) $(OF_PROJECT_LIBS) $(TARGET_LIBS)
	@echo 'Linking $(TARGET) for $(ABI_LIB_SUBPATH)'
	@mkdir -p $(@D)
	$(CXX) -o $@ $(OF_PROJECT_OBJS) $(OF_PROJECT_ADDONS_OBJS) $(TARGET_LIBS) $(OF_PROJECT_LIBS) $(LDFLAGS) $(OF_CORE_LIBS)  -lboost_system -lboost_timer -lboost_thread 

• Ventana
  • ofGetWidth(), ofGetHeight()
• Programa
  • ofGetElapsedTimef(), ofGetElapsedTimeMicros(), ofGetElapsedTimeMillis()

• TWO_PI
• DEG_TO_RAD (any number we multiply by DEG_TO_RAD will be converted to radians)

Crear un listener de UDP:

#include "ofxNetwork.h"
 
ofxUDPManager udpConnection;
 
udpConnection.Create();
udpConnection.Bind(5001);
udpConnection.SetNonBlocking(true);
 
char udpMessage[10000];
udpConnection.Receive(udpMessage,10000);
std::string message=udpMessage;

#include "ofxJSON.h"
...

std::string url = "http://127.0.0.1:5000/sketch/1";
bool parsingSuccessful = result.open(url);
 
if (parsingSuccessful)
{
	//ofLogNotice("ofApp::setup") << "Ok!" << endl << result.getRawString() << endl;

	ofLogNotice("ofApp::setup") << result2.parse("{\"hola\": \"adios\"}");
	ofLogNotice("ofApp::setup") << result2["hola"].asString();
}
else
{
	ofLogNotice("ofApp::setup")  << "Failed to parse JSON" << endl;
