Question

I’ve downloaded and installed Cinder and even run the TinderBox tutorial to create a Cinder project in XCode.

However i’m keen to use eclipse as my IDE and not Xcode.

I’m running OSX 10.8.2

Having followed the following tutorials to configure eclipse Configure Eclipse and Vimeo Video, I encountered a number of issues compiling and linking.

make *** Error 1 C/C++ Problem cinder
undefined symbols for architecture i386:

I figure i’ve either not followed the tutorial posts to the letter or there is some difference in my setup.

Note: this is a Question Answer post.

** Configure eclipse **

Assumes that you have a C++ version of eclipse and have created a basic C++ Cinder project. You can find the .h and .cpp files in the appendix below. The following outlines the settings you need to configure to compile.

Step 1.

1. Open the project ‘properties’ window.
2. Navigate to the C/C++ Build > ‘Build Variables’ option.

Add the following Variable.

CINDER_PATH /path/to/cinder_0.8.4_mac/

Step 2.

1. Navigate to the C/C++ Build > Settings window.
2. Under the Tools Tab select the ‘MacOS X C++ Linker’ option.

Here, in the ‘command’ input field you need to add after the g++ your command line options and OSX framework references

g++ -m32 -arch i386 -framework Cocoa -framework IOKit -framework Accelerate -framework AudioToolbox -framework AudioUnit -framework CoreAudio -framework CoreVideo -framework CoreServices -framework QTKit -framework OpenGL -framework QuickTime -framework AppKit -framework Cocoa -framework CoreData -framework Foundation

-m32 Tells the link to use 32 bit rather than 64 bit.

-arch i386 Ensures we link for the correct architecture.

-framework Reference the frameworks required to run Cinder (As i understand it currently)

NOTE: Depending on your mac version you might find -framework Carbon in stead of -framework Cocoa, I used Cocoa. 

Step 3.

1. Navigate to the ‘MacOS X C++ Linker’ > ‘Libraries’ option

2. Add the following library search paths. ( -L command line)

   ${CINDER_PATH}/lib
   ${CINDER_PATH}/lib/ios-sim
   ${CINDER_PATH}/lib/ios
   ${CINDER_PATH}/lib/macosx

Add the following libraries to include ( -l command line)

cinder
cinder_d
z
png14
pixman-1
cairo
boost_thread
boost_system
boost_filesystem
boost_date_time
cinder-iphone-sim_d

Step 4.

Under the ‘MacOS X C++ Linker’ menu select the ‘Miscellaneous’ option and add the following in the XLinker field.

${CINDER_PATH}/lib/libcinder_d.a

NOTE: It was adding this option along with the -arch i386 option that resolved this error "undefined symbols for architecture i386:"

Step 5.

1. Select the “GCC C++ Compiler” menu option.

2. Add the following in the ‘command” field.

   g++ -m32 -arch i386

Select the ‘Includes’ menu option and add the following folder paths

${CINDER_PATH}/boost
${CINDER_PATH}/include
/System/Library/Frameworks

** Issues encountered and solutions **

Problem A

make *** Error 1 C/C++ Problem cinder
undefined symbols for architecture i386:

Solution A

I found that there were two contributing factors to overcoming this issue. The first was adding the -m32 and -arch i386 command line options to the linker and compiler settings.

The second was that inclusion of the following -XLinker option

${CINDER_PATH}/lib/libcinder_d.a

Note: The above is for debug mode, (The _d) for release you have to set it to

${CINDER_PATH}/lib/libcinder.a

** Appendix **

HelloWorld.h

#include "cinder/app/AppBasic.h"
#include "cinder/gl/gl.h"

using namespace ci;
using namespace ci::app;
using namespace std;


class HelloWorld : public AppBasic {
  public:
    void setup();
    void mouseDown( MouseEvent event );
    void update();
    void draw();
    void prepareSettings(Settings * settings);
};

HellowWorld.cpp

#include "HelloWorld.h"
// You dont' need this when you have the CINDER_APP_BASIC line below.
//int main(int argc, char **argv) {
//  return -1;
//}


void HelloWorld::setup()
{

}

void HelloWorld::mouseDown( MouseEvent event )
{
}

void HelloWorld::update()
{
}

void HelloWorld::draw()
{
    // clear out the window with black
    gl::clear( Color( 0, 0, 0 ) );
}

void HelloWorld::prepareSettings(Settings * settings)
{
    settings->setWindowSize( 800, 600 );
    settings->setFrameRate( 60.0f );
}

CINDER_APP_BASIC( HelloWorld, RendererGl )
