Hi Jordi,
Thanks for the instructions, and sorry for taking so long to respond. I had to
upgrade Xcode to 4.3.1 for a different project and ran into many projects. I'm
wondering if this is responsible for your cmake toolchain not working for me.
XCode 4.3.1 is the .app version, which removes your /Developer folder, which is
a pretty significant change.
I had to change your toolchain file to point to the new SDK location:
Code:
#set(IOS_DEVELOPER_ROOT "/Developer/Platforms/${IOS_TARGET}.platform/Developer")
set(IOS_DEVELOPER_ROOT
"/Applications/Xcode.app/Contents/Developer/Platforms/${IOS_TARGET}.platform/Developer")
But when I run cmake, I get a compiler error:
Code:
$ cmake -DCMAKE_TOOLCHAIN_FILE=iOS5_GLES2.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not
be built correctly.
Missing variable is:
CMAKE_FIND_LIBRARY_PREFIXES
CMake Error: Error required internal CMake variable not set, cmake may be not

It fails with the following output:

I saw in another post (http://forum.openscenegraph.org/viewtopic.php?t=9951)
that you were using clang. What version?
Mike is:
Apple clang version 3.0 (tags/Apple/clang-211.11) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.3.0
How far are you from finishing your GLES2 example? I'm eager to try it...
assuming I can get OSG to build properly.
Any ideas are highly appreciated.
Thanks,
Mike
