Clang und C++11
-
Hoi,
Ich wollte mal testen ob mein GCC-Code auch ohne murren mit Clang läuft. Also mal das CMakeLists.txt angepasst:if(CMAKE_COMPILER_IS_GNUCXX OR "${CMAKE_CXX_COMPILER_ID}" MATCHES "Clang") set(CMAKE_CXX_FLAGS "-std=c++0x -Wall -Wextra -pedantic") set(CMAKE_CXX_FLAGS_DEBUG "-O0 -g") set(CMAKE_CXX_FLAGS_RELEASE "-O3 -s -DNDEBUG") endif()Dann einfach unter Ubuntu 11.10 per Paketverwaltung clang installiert, Version 2.9 .
Im C++03-Modus klappt das auch ganz gut, im C++11 Modus hängt er sich aber sofort an am ersten STL-Header auf:

You can use Clang in C++11 mode either with libc++ or with gcc's libstdc++. Patches are needed to make libstdc++-4.4 and libstdc++-4.7 work with Clang in C++11 mode.
Heißt das dass libstdc++-4.6 überhaupt nicht mit Clang funktioniert oder muss ich die nur nicht patchen?
Erbitte Rat!
Danke und Grüße,
Ethon

Ich vermute mal, dass Version 2.9 einfach nicht den benötigten C++11 Support hat. Probiers doch mal mit 3.0 oder 3.1.
-
Ich benutze Clang 3.2 (Trunk) mit GCC 4.7. Bei mir funktionieren alle Header bis auf chrono und thread / mutex. Ich weis nicht, wie viel C++11 Clang 3.2 unterstützt. (Guck mal hier: http://clang.llvm.org/cxx_status.html). Vielleicht ist ja bei den GCC headern was dabei, das Clang nicht unterstützt?
PS: Da ich gerade gesehen habe, das Clang 3.1 schon in [Testing] von archlinux ist, downgrade ich gerade
(Clang 3.1 unterstützt alle von mir benötigten C++11 Features )
-
Stimmt, mit Clang 3.0 kompiliert zumindestens der STL-Teil ... dafür hängt es jetzt bei Boost.Filesystem ... grr.
-
Kann jemand die Fehler zuordnen? Boost sollte mit Clang 3.0 auf jeden Fall kompilierbar sein, wie ich gelesen habe:

Mit Clang 3.1 wenn ich dich korrekt verstanden habe?
Aber wieso gibt es bei dir nicht die No-Newline-Warnung?

Aber wieso gibt es bei dir nicht die No-Newline-Warnung?Ja, Clang 3.1. Die Newline Warnung gehört bei Clang 3.1 zu -Wc++98-compat, also gibt es sie scheinbar in C++11 nicht mehr. Und du willst ja keine C++98-Kompatibilität, oder? Ich habe nochmal alles mit -Weverything -Wno-c++98-compat -Wno-c++98-compat-pedantic compiliert, hier ist das Ergebnis: https://gist.github.com/e1d8a48f68223328cba0
Die clang: warning: -lc++abi: 'linker' input unused when '-c' is present kannst du ignorieren, das liegt daran, dass man bei CMake keine Linkerflags angeben kann, ich bei libc++ aber libc++abi linken muss.
