I am looking through the recently open-sourced NVidia PhysX 3.4 and all I find are C++ classes - is the a header version or wrapper API that is C only?
May be you must create your C Header wrapper C++ classes yourself. I did something similar here by this article and it work well.

I want to use some of the non-standard GLES 2 extensions like 'GL_OES_vertex_array_object' but I can't find a way to use them with Marmalade SDK. I guess I have to initialize them with a marmalade related function like the wglGetProcAddress on Windows but I can't find anything about this on the net. Currently my code compiles fine, but on the linking process I get "unresolved external symbol" errors. Is there a way I can use these extensions with Marmalade?
This is covered in Marmalade Documentation.
I am one of the Marmalade SDK developers, and as I know support of GLES2 drivers was not finished yeat. This functionality should be released somewhere in the end of August. I know defenetly that it will not work for OSX.
I try to use objective-c in linux.
Which version of iOS is "supported" when using compilers like gobjc++, gobjc, libgnustep-base-dev
None. I don't know of any non-Apple tool chain that can be used to compile Objective-C for iOS devices. For a start, you at least need an ARM cross compiler.
Has anyone used Google's Protocol Buffers when developing applications in Objective-C?
Are there any current projects for compiling .proto files into Objective-C, all the Google docs simply refer to Java, C++ or Python.
I've been working on an fork of Cyrus' project. It's based on protobuf 2.3 and works as a protoc plugin (protoc-gen-objc) instead of requiring a modified protobuf distribution.
You can find it as the protobuf-obj project on GitHub.
The Third Party page lists this Objective-C port. Unfortunately the project appears to be empty at the moment, but it's encouraging to see it anyway. I had heard internal rumours of the project, but hadn't seen it as an open source project before today.
You could get in touch with the project owner (Cyrus Najmabadi) to ask about it though...
(Small piece of trivia - Cyrus used to work on the C# team in Microsoft before he joined Google.)
This may or may not be helpful, but Apache Thrift (originally developed at Facebook) supports Cocoa, and seems to have people attempting to use it in the iPhone.
Thrift officially supports more languages. But Protocol Buffers have 5x the Stack Overflow interest, so who knows if it's a good replacement in terms of maintenance—not to mention compatibility with your own project! Still, maybe it's worth consideration.
I just asked a related question you may find helpful if it gets good answers: Any success using Apache Thrift on iPhone?
Protocol Buffers v3 supports Objective-C
Protocol Buffers v3 supports Objective-C as a first class language.
To generate Objective-C code from a .proto file call the compiler with the objc_out option:
protoc --proto_path=src --objc_out=build/gen src/foo.proto src/bar/baz.proto
I prefer to use c++ generated classes within my objc projects, works just fine.
I did try the objc PB version but without success.
I'm working on a cross-platform solution currently. The solution uses XmlMtomReader and XmlMtomWriter from .NET framework 3.0.
Now i need to know if these two classes (and all the nessasary infrastructure around them) are fully supported in Mono project from the porting-it-to-linux point of view. :)
You can check it on the mono status:
http://go-mono.com/status/
You can also check your code using the mono migration analyser
http://www.mono-project.com/MoMA
I checked they are currently not implemented
The APIs are available on the current Mono 2.6 preview, but they are not available on the 2.4 release (the current official release).
I want to access COM objects using Python 3.1, but I can't find a library to support 3.x. Do I need to use some extension or there is something in the standard library?
Try the PyWin stuff. It provides (among other things, like direct support for Win32 APIs) a COM bridge for Python and now supports both 2.x and 3.x.
Older downloadable releases are available here.
