I created a new cocos2dx ios project and succeeded to build and run it on ios simulator. But when I try to add a function like
void setImageSize(cocos2d::CCSprite *image, cocos2d::CCSize size);
I got this error.
Undefined symbols for architecture i386:
"HelloWorld::setImageSize(cocos2d::CCSprite*, cocos2d::CCSize)", referenced from:
HelloWorld::initPhysics() in HelloWorldScene.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I'm new to cocos2dx.
Thanks in advance

here is the error description:
Undefined symbols for architecture x86_64: "_verify", referenced
from:
_HIDGetDeviceInfo in HIDUtilities.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code

It happened after upgrade Xcode to version 9.1
HIDUtilities.o is not third-party SDK, HIDUtilities.h and HIDUtilities.c are files in my project.
Any suggestion is appreciated, thanks in advance.
I write a cross-platform audio processing program. It uses Qt 5 and PortAudio library. The platform is Mac OS X Yosemite, clang compiler, Qt Creator 3.4.1 IDE. I got those linker errors:

What does it mean and what needs to do?
I am working on facial recognition in video using opencv. I followed the tutorial on opencv's website(http://docs.opencv.org/modules/contrib/doc/facerec/tutorial/facerec_video_recognition.html). I get following error when I try to build my code in xcode.
Undefined symbols for architecture x86_64:

I made a few changes to the code as given in here fatal error: opencv2/contrib/contrib.hpp' file not found (open cv already built)
Please guide me through it as I am new to opencv.
Thanks in advance!
Has anyone had this issue on mac while installing boost or know how to fix? I seem to have everything together but this error. I am using OS X 10.10 & and Xcode 6.1.1.
This is what I used for the install and to make the framework.

I have downloaded SDL2 and am trying to build it using the terminal command
./configure --prefix=/home/user/SDL && make && make install
It runs through a laundry list of things, before eventually stopping after spitting out:

_SDL_iconv_string in SDL_iconv.o

ld: symbol(s) not found for architecture x86_64

make: *** [build/libSDL2.la] Error 1
I have hunted and hunted and have no idea what to do about this. Help?
EDIT:
Breaking it up, ./configure alone works, and then running make afterwords throws up these errors. I don't know if that helps at all.
