objective c - Can you use C++ libraries in a Cocoa (Obj-C) project? -


i'm considering learning objective-c , cocoa, in order use apple's tools , guis.

however, i'd graphics programming; openframeworks , cinder 2 libraries catch eye, we're in c++ land.

i come java/swing/processing background... don't know c family. how can call c , c++ libraries, cinder , of, native cocoa?

and, bonus points: solution work on iphone or ipad?

in short, c++ fine os x , ios programs, , plays objective-c quite nicely.

in more detail:

however, i'd graphics programming; openframeworks , cinder 2 libraries catch eye, we're in c++ land.

i won't speak libraries directly.

to answer question in more general terms: c++ fine in app, since c, c++, objc, , objc++ first class development languages ios apps.

i come java/swing/processing background... don't know c family. how can call c , c++ libraries, cinder , of, native cocoa?

objective-c++ allows use c, c++, , objective-c in same translation. feel free use/combine c++, c, or objc needed. compile times increase, , there restrictions* if take route. otherwise, support good. apple uses amount of c++ in apps/libs.

and, bonus points: solution work on iphone or ipad?

definitely. c++11 support ios , os x bit behind. however, clang team's been adding support very quickly. there bumps if want latest features, i'd hold on bleeding edge c++ , compiler features if project depends on it. of course, not hurt sample program using latest clang features each release in order determine how works programs.

update: @ point (nov 8, 2011) clang can handle of c++ 2003 code throw @ it. code speed , size vary compared gcc+llvm. not want drop either @ point, both compilers work me c++ 2003, , apple's gcc not support c++11, it's time start testing clang if want c++11 features in near future.

  • c++ ideal (imo) general performance critical development on ios, long team knows how use it.
  • mixing c, objc , c++ powerful if use right features of each language right reasons, , compatibility exists. reaches years os x (although compiler gcc @ time).

*restrictions: these reasonable restrictions - features need exist, there things people may expect not possible. common inability derive types of different object models. is, cannot reasonably not create c++ type objc type, can freely declare ivars of multiple types in either object type.

for class project i'm attempting write vst plugin backed cuda. current cuda workflow on linux box, i'd prefer compile , link there. according wikipedia , should possible (i couldn't find steinberg documentation relevant linux) can't find makefile or instructions on how build if aren't using xcode or visual studio. i'm vst 3 sdk doesn't support linux. when try compile plugin under linux, error: ./base/source/fatomic.cpp:39:30: fatal error: libkern/osatomic.h: no such file or directory this issue caused following code in "vst3 sdk/base/source/fatomic.cpp" #if mac #include <libkern/osatomic.h> #if mac_os_x_version_min_required > mac_os_x_version_10_4 #define native_atomic_type (volatile int32_t*) #else #define native_atomic_type (int32_t*) #endif #elif windows #include <windows.h> #endif but hope compiling under linux work vst sdk 2.4. reading. jvstwrapper seems run on lin...
