[llvm-dev] Compiling SAFECode poolalloc in cygwin create different libraries compared to linux.

[John Criswell via llvm-dev]

Dear Kiran,

Which version of LLVM/SAFECode are you using?  Is it LLVM 3.2?

I'm guessing that you're using LLVM 3.2 and trying to compile 
safecode/tools/LTO (that's the only component that links in 
AssistDS.a).  You could try changing the following line:

$(PROJ_OBJ_ROOT)/$(BuildMode)/lib/libAssistDS.a: 
$(POOLALLOC_OBJDIR)/$(BuildMode)/lib/AssistDS.a

... to:

$(PROJ_OBJ_ROOT)/$(BuildMode)/lib/libAssistDS.a: 
$(POOLALLOC_OBJDIR)/$(BuildMode)/lib/libAssistDS.a

You'll need to fix the problem for other libraries for which SAFECode 
creates links in its own object tree (such as libpoolalloc.a).

That might fix the problem on Cygwin.

Regards,

John Criswell
