Duncan,
I am unable to complile dragonegg 3.2 with FSF gcc 4.7 due the the
compiler errors...

Have you noticed this issue on linux? It seems to introduce an unwanted compiler
dependency for building
dragonegg.

Hi Jack, this occurs because you compiled LLVM with clang (right?) and dragonegg is compiled with the same flags used to compile LLVM (it is an llvm-config bug in my opinion that llvm-config output includes these kinds of optional flags).

I believe both fink and MacPorts now default to the clang compiler on later darwin. The following change to the dragonegg 3.2 Makefile solves the problem here... --- dragonegg-3.2/Makefile.orig 2012-12-07 12:50:30.000000000 -0500 +++ dragonegg-3.2/Makefile 2012-12-07 12:51:21.000000000 -0500 @@ -42,8 +42,8 @@ else COMMON_FLAGS+=-fvisibility=hidden endif -CFLAGS+=$(COMMON_FLAGS) $(shell $(LLVM_CONFIG) --cflags) -CXXFLAGS+=$(COMMON_FLAGS) $(shell $(LLVM_CONFIG) --cxxflags) +CFLAGS+=$(COMMON_FLAGS) $(shell $(LLVM_CONFIG) --cflags | sed -e 's/-Wcovered-switch-default//') +CXXFLAGS+=$(COMMON_FLAGS) $(shell $(LLVM_CONFIG) --cxxflags | sed -e 's/-Wcovered-switch-default//') ifeq ($(shell uname),Darwin) LOADABLE_MODULE_OPTIONS=-bundle -undefined dynamic_lookup @@ -76,7 +76,7 @@ ALL_OBJECTS=$(PLUGIN_OBJECTS) $(TARGET_OBJECT) $(TARGET_UTIL_OBJECTS) -CPP_OPTIONS+=$(CPPFLAGS) $(shell $(LLVM_CONFIG) --cppflags) \ +CPP_OPTIONS+=$(CPPFLAGS) $(shell $(LLVM_CONFIG) --cppflags | sed -e 's/-Wcovered-switch-default//') \ -fno-rtti \ -MD -MP \ -DIN_GCC -DLLVM_VERSION=\"$(LLVM_VERSION)\" \ so that FSF gcc 4.7.2 can be used to build dragonegg again.
