I am fairly new to c++ and I need to use regular expressions and more libraries of that type that do not come with Xcode. I have found boost but i dont know how to install it. I thought it worked but it did not recognize the regex library for boost. I typed it in correctly.
thanks
If you use libc++, which comes with Xcode 4.4, then you can use the C++11 <regex> library. Just go to the project's build settings and set the C++ standard library to be libc++. Turn on C++11 while you're at it.

I'm building a C++11 program that works on osX, but the build for android fails with "error: 'round' is not a member of 'std'".
This is a known problem, associated with the gnustl standard library (https://code.google.com/p/android/issues/detail?id=54418), and the current best workaround seems to be to link against LLVM libc++.
How to do so is documented here for Android Studio or cmake, but I cannot find any documentation for how to do the same with bazel, if it is possible.
A partial answer:
if just building an android static library, the command line call has to specify crosstool_top. This can be set to a specific toolchain using something like --crosstool_top=#androidndk//:toolchain-libcpp.
Options can be found in external/androidndk/BUILD in the directory generated by bazel.
However, if building the library as part of an android application, the crosstool would be inferred. I don't know whether the same approach works, or if not what the answer would be.
I'm having trouble linking an Xcode project using the AAF SDK, with Xcode 5.1.1 on MacOS 10.9.5. When I link the main dynamic library, these symbols come up missing:
_StgCreateDocfile
_StgCreateDocfileOnILockBytes
_StgOpenStorage
_StgOpenStorageOnILockBytes
AssertProc
I can't find a definition for them anywhere in the entire source tree for the SDK. The first four appear to be part of Structured Storage on Windows. A Structured Storage library is provided in the SDK and I'm already linking that.
Can anyone tell me of a Mac system library that defines these? Or is there a linker argument that pulls in a library for them? Thanks for any help.
A late answer (!), but in case anyone comes across this... The solution is either:
To use the makefiles with the AAF SDK to generate the AAF dylib,
which works fine. or...
If you use Xcode to build the AAF SDK, ensure the correct
#defines are kept, namely:
_DEBUG OM_DEBUG OM_STACK_TRACE_ON_ASSERT OM_USE_SCHEMASOFT_SS OM_STRUCTURED_STORAGE
Note that DEBUG=1 is absent (it is added by default by Xcode) - if defined, this brings in AssertProc. Define NDEBUG on release builds and omit the debug defines.
The Stg... functions are part of the MS implementation of Structured storage as you stated, but should not be referenced on a Mac, the Schemasoft implementation being used.
I am currently writing c++ code and compiling using Xcode. I was wondering: How can I find out which c++ compiler is Xcode 5 using?
I would like to know that to make sure that the program I am writing is compilable on other computers that don't necessarily use the same compiler.
Thanks in advance!
You can also check your target's build settings to see what the current setting is. However, Xcode 5 only uses the LLVM 5.0 compiler. GCC is no longer used.

I want to write an own c/c++ IDE with syntax-check etc. And of course I need a compiler-functionality. For this I want to use gcc, I think it is a good option, isn't it? The IDE should not call a gcc-binary to compile, it should include the gcc source code, because after compiling the IDE I want a stay alone executable.
So my question: Is there sth like a tutorial or a good hint how to realize this?
btw it's for Mac, I'll write the IDE with XCode
Thank you!
Use LLVM's Clang and its libClang API, it's built for this purpose. GCC is not made to be used as a library.
You might develop a plugin for GCC, or a GCC MELT extension. But it could be that on MacOSX GCC plugins are not supported yet. You might also look into GCCSense which might fill some of your goals (but I never used it).
I have install g++-4.5, as I'm interested in the C++0x stuff (done by sudo port install gcc45). Now I've made sure it's my default compiler (using gcc_select) and all of my Makefile projects do just fine compiling with 4.5.
Now I'm starting a project in xCode 4. How do I get the same C++0x features from within xCode, a.k.a. tell xCode to use g++-4.5?
These two bloggers describe hacking together an Xcode plugin to use one's own build of clang. I imagine you could use the same thing but substitute gcc 4.5's path.

I've been meaning to try, and found your question in my research.
