[Insight-users] Using ITK in a Cocoa App (+Xcode)

[Darren Weber]

Hard to see exactly, but it looks like the include path for ITK is unusual
(to my eye, the 'iquote' option to gcc or g++ is unusual):

-iquote/Users/saut/thrill/include/InsightToolkit/Common

Nevertheless, it should work, from the man page:

"
4459        -iquote dir
    4460            Search dir only for header files requested with
"#include "file""; they are not searched for
    4461            "#include <file>", before all directories specified by
-I and before the standard system
    4462            directories.
"

Also, I'm no expert on the gcc suite, but I generally call g++ for any c++
programs (one would have to believe that the Apple Xcode and bundled gcc
suite is able to resolve gcc calls for Objc-C++ programs correctly).
