linker-errors

I'm integrating 3rd party code into my MFC app under Visual Studio 2010. When in Debug mode the following build error occurs: 1>LIBCMT.lib(invarg.obj) : error LNK2005: __initp_misc_invarg already defined in libcmtd.lib(invarg.obj) 1>LIBCMT.lib(invarg.obj) : error LNK2005: __call_reportfault already defined in libcmtd.lib(invarg.obj) 1>LIBCMT.lib(invarg.obj) : error LNK2005: __set_invalid_parameter_handler already defined in libcmtd.lib(invarg.obj) 1>LIBCMT.lib(invarg.obj) : error LNK2005: __get_invalid_parameter_handler already defined in libcmtd.lib(invarg.obj) 1>LIBCMT.lib(invarg.obj) :

I'm following the steps in HOWTOBUILD.txt . I have the necessary files for glfw built already. For the first time, the linker is complaining about glfw. After searching, it seems I need to link against gl3w see this link . I've generated the static libs for gl3w . Now, I've opened a new project and included the path to include , see the below picture. For the linker, I've linked against glfw3dll.lib gl3w.lib opengl32.lib and included their path. If I run the sample from the first chapter, main.cpp #include "sb7.h" class my_application : public sb7::application { void render(double currentTime)

I'm trying to run a GHUnit test to just test that a setter actually works for a NSManagedObject object in my app. My app is called Machine and my GHUnit target is called Tests. I've added Machine as a dependency to the Tests target. My object in the test is called Goal. Here is the code and the error in the Link is shown below. #import <GHUnitIOS/GHUnit.h> #import <CoreData/CoreData.h> #import "Goal.h" #import "GoalRec.h" @interface ControllerTests : GHTestCase { } @property (retain) Goal *goal; @end @implementation ControllerTests @synthesize goal; - (BOOL)shouldRunOnMainThread { // By

I am compiling a test program to test the fftw3 (ver3.3.4). Since it is not installed with root previlidge the command I used is: gcc -lm -L/home/my_name/opt/fftw-3.3.4/lib/ -I/home/my_name/opt/fftw-3.3.4/include/ fftwtest.c where the library is installed in /home/my_name/opt/fftw-3.3.4/ My code is the 1st tutorial on fftw3's website: #include <stdio.h> #include <fftw3.h> int main(){ int n = 10; fftw_complex *in, *out; fftw_plan p; in = (fftw_complex*) fftw_malloc(n*sizeof(fftw_complex)); out = (fftw_complex*) fftw_malloc(n*sizeof(fftw_complex)); p = fftw_plan_dft_1d(n, in, out, FFTW_FORWARD,

I'm working on MacOSX 10.7.2 and Xcode 4.2.1. I installed libpng using port and I was trying to load a PNG image in my application, but I get linker errors: Undefined symbols for architecture x86_64: "_png_create_read_struct", referenced from: loadPngImage(char*, int&, int&, bool&, unsigned char**) in test.o "_png_create_info_struct", referenced from: loadPngImage(char*, int&, int&, bool&, unsigned char**) in test.o "_png_destroy_read_struct", referenced from: loadPngImage(char*, int&, int&, bool&, unsigned char**) in test.o "_png_set_longjmp_fn", referenced from: loadPngImage(char*, int&, int
