I used Homebrew to install gphoto2 and libgphoto2 for use in a camera-control application using C++. I have confirmed that header files were linked in /usr/local/includes:

Based on the sample code available at https://github.com/gphoto/libgphoto2/tree/master/examples, it seems like I should be able to use includes such as #include <gphoto2/gphoto2.h> to access the header files, but that approach has failed using both Clang and Xcode as the compiler. The files are not found. What am I doing wrong?

can you try making a small program and then compiling it with gcc and then pasting the output here...Also try using ls or similar command to see if the file is accesible or not.. – Jay Rajput Oct 30 '16 at 02:02
Are you compiling in Terminal or in XCode? In Terminal you need `clang -I/usr/local/include ...` – Mark Setchell Oct 30 '16 at 08:32
