after poking llvm.cygport, i realized this 'cause a broken patch from cygwin ports. maybe, llvm-3.1 itself has no task for this bug.

umm, this patch fix build, but it does not work after installing b/c llvm-config's library handling is totally broken. real fix for 3.1 seems overwork so ill try cygwin specific workaround later.

updated, it looks ok to me even after installing.

same here. making llvm-3.1-4.cygport w/o --enable-shared is the answer?

i tried cygwin-ports llvm git[1] w/o --enable-shared, but it fails.

I am using llvm supplied from Cygwin.

What is your configuration?

./config.status --version

I guess you are configured with --enable-shared.

It seems llvm-config is still incompatible to shared libs... See also bug 6823. Note that llvm-config has been rewritten since then. (For now, I will not mark this as DUPLLICATED)
