When I try to compile my simple code which is meant to resize a image file using ImageMagick library, I'm getting the following error.
$ gcc `pkg-config --libs --cflags ImageMagick` imagemagick_example.c

I searched for a way to fix this for an hour and couldn't find any works.
I'm using macOS 10.13.1 and home-brew installed ImageMagick 7.0.7-14.
Use MagickWand for the C API.
gcc `pkg-config --libs --cflags MagickWand` imagemagick_example.c
Or skip pkg-config and use the helper utility that shipped with ImageMagick.
MagickWand-config --libs --cflags

I'm facing a problem, my project don't want to compile because of
some framework mismatch.

I think its about TQEventListener which need a framework, but I'm not sure...
I was trying to install mpi on my Mac (running Yosemite) and I ran the following:
brew update
brew install open-mpi
Everything seemed to go okay, but when I tried to compile my file mpi.cpp, I received:

I'm not really sure what to make of this. Is there an additional step?
Can't figure this out. Tried making a completely new project and it still doesn't work. This app uses GoogleMaps. Error below:

Try importing CoreBluetooth.framework and Accelerate.framework. Also use "-ObjC" instead of "-all_load" in under "Other Linker Flags".

Please help
I have an older system (OSX 10.6.8 with xcode 4.0) and I'm trying to get OpenCV 2.3.0 to work on it. The problem that I can't resolve is that whenever I try to use the flann library, my xcode gives me a Mach-O linker error. So far I've tried recompiling the all the libraries and building the dylib from a different source, but it hasn't helped. When I check the library in terminal, i get
Freddi-2:OpenCV-2.3.0 fredchen$ file /usr/local/lib/libopencv_flann.dylib
/usr/local/lib/libopencv_flann.dylib: Mach-O 64-bit dynamically linked shared library x86_64
My specific error code is:

The dynamic libraries I have linked with the project are:
libopencv_video.2.3.0.dylib
libopencv_objdetect.2.3.0.dylib
libopencv_ml.2.3.0.dylib
libopencv_legacy.2.3.0.dylib

libopencv_features2d.2.3.0.dylib
libopencv_core.2.3.0.dylib
libopencv_calib3d.2.3.0.dylib
I'd appreciate any help. Thanks!
I remember having similar errors when I was using 2.3.0 on Mac. You should try to stick with the latest version, either 2.4.4 or the latests from github.
