J'ai l'impression que dans la doc ils disent que sa marche mais je ne comprend pas tres bien l'anglais et j'ai pas envie de faire de betises.
Voila un extrait de la doc:
New in Xcode IDE
• The assistant interface has been completely revamped, making it easier to
create "New Project", "New Target", and "New File" resources. This release of
Xcode also adds new assistant templates for both Mac OS X and iPhone OS
applications.
• A new Overview toolbar item lets you see and set the project's active Target,
Configuration, Executable, Architecture, and SDK with a single control.
• It is now possible to set a global "override" SDK as the Active SDK, making it
easy to test the build of your entire project against a different platform.
• New interface shortcuts have been added to the Build Setting inspectors
making it easy to set the desired compiler, architectures, and SDKs
• You can now add Libraries and Frameworks directly into the Target window and
relate them to the project's SDK.
• The Xcode UI now allows you to designate a library or framework as weak-
linked, to support building with newer SDKs while targeting older OS versions.
• New "Edit all in scope" option within the Xcode source editor makes it easy to
update all instances of the selected symbol within the current scope of code.
• You can now have conditional build settings assigned for any combination of
architecture and SDK.
• LLVM GCC 4.2 is a new optional compiler based on the LLVM.org open source
project. LLVM GCC 4.2 provides an LLVM-based back-end optimizer using the
GCC 4.2 front-end parser. This compiler is both source and binary compatible
with GCC 4.2 and requires the Mac OS X 10.5 SDK or "Current OS" SDK.
• GCC 4.2 is a new optional compiler with stricter C and C++ language
enforcement, security enhancements, performance optimizations, and bug fixes
over GCC 4.0. Requires the Mac OS X 10.5 SDK or "Current OS" SDK
Quand je lance la commande g++ dans le terminal voila ce que j'ai:
i686-apple-darwin9-g++-4.0.1: no input files
Donc j'imagine que j'ai GCC 4.0.1 d'installer?
