llvm dev - Dec 2009 - [LLVMdev] LLVM 2.6 cygwin build fails

Hi,

I'm trying to build LLVM 2.6 (from svn branch release_26) on cygwin
1.7, and I have the following errors with both GCC 3.4.4 and GCC 4.3.4

This is what I got after

  ./configure --enable-optimized --enable-targets=x86
  make -j2

Can anybody help me with this?

GCC version info:

  gcc-3 (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
  gcc-4 (GCC) 4.3.4 20090804 (release) 1

Binutils version 2.19.51-1.

Cygwin does not support dynamic linking (as any windows target).
For the moment - you can just build tools and not the runtime via
"make tools-only".
