llvm dev - May 2005 - [LLVMdev] [Cygwin] onsistant error building LLVM

Consistant error building LLVM on Cygwin from CVS :-

Don't know what is causing it.

If you look in X86JITInfo.cpp, you'll find CompilationCallback. I'm not
sure about CompilationCallback2. In any event, the code is conditionally
compiled and that might be tripping things up on Cygwin.

I have done another test and it seems to be my cygwin development 
environment :(

I cannot seem to reproduce my previous Cygwin environment on which we got 
LLVM and the frontend tested.

Oh well I'll try again. It just seem such a long development cycle to test. 
When I am ment to be testing my instillation instructions !

Try, try again...

X86CompilationCallback2 is also defined in X86JITInfo.cpp.  One is a thin
assembler wrapper around the other.  No matter how things are conditionally
compiled, both functions will be present.  Is X86JITInfo.cpp itself being
compiled?

Also, this error:

/usr/src/llvm/lib/Target/X86/X86ISelPattern.cpp:73: undefined reference 
to `X86CompilationCallback2'

doesn't make sense.  X86CompilationCallback2 is not visible outside of 
X86JITInfo.cpp, and line 73 of X86ISelPattern.cpp is in the middle of a 
comment block.
