Hello,

Finally I succeeded in compiling SafeCode
for LLVM 3.2 within CygWin.

Unfortunately during the test I got
the following error message:

Has anybody an idea where this message
has it root cause. Obviously SafeCode is not working because the enable
switch -fmemsafety
 
is not recognized...how could this happen?
Is this message known?


Adaption changes in the SafeCode->Tools->LTO->Makefile
that may cause this behaviour:
 
//Added this
$(PROJ_OBJ_ROOT)/$(BuildMode)/lib/libLLVM-3.2svn.so: $(LLVM_OBJ_ROOT)/$(BuildMode)/lib/libLLVM-3.2svn.so
    $(VERB) echo "Creating symlink to $@"
    $(VERB) ln -fs $< $@

//Changed -> when compiling this in
linux this change seems not to be needed!
$(PROJ_OBJ_ROOT)/$(BuildMode)/lib/libAssistDS.a:
$(POOLALLOC_OBJDIR)/$(BuildMode)/lib/AssistDS.a   ==> changed AssistDS.a
to libAssistDS.a
    $(VERB) echo "Creating symlink to $@"
    $(VERB) ln -fs $< $@
$(PROJ_OBJ_ROOT)/$(BuildMode)/lib/libLLVMDataStructure.a:
$(POOLALLOC_OBJDIR)/$(BuildMode)/lib/LLVMDataStructure.a   ==>
changed LLVMDataStructure.a to libLLVMDataStructure.a
    $(VERB) echo "Creating symlink to $@"
    $(VERB) ln -fs $< $@
$(PROJ_OBJ_ROOT)/$(BuildMode)/lib/libpoolalloc.a:
$(POOLALLOC_OBJDIR)/$(BuildMode)/lib/poolalloc.a   ==> changed
poolalloc.a to libpoolalloc.a
    $(VERB) echo "Creating symlink to $@"
    $(VERB) ln -fs $< $@
