[cfe-dev] Building clang with MingW and MSYS

Wed Mar 16 13:20:44 PDT 2011

I am trying to build clang with MingW and MSYS. I have followed the 
instructions on the Clang "Getting Started" page. When I execute:

../llvm/configure

I receive:

$ ../llvm/configure
configure: error: Already configured in ../llvm

Huh ?

There are no files in the 'build' directory except for a config.log 
which says:

"This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by llvm configure 3.0svn, which was
generated by GNU Autoconf 2.60.  Invocation command line was

   $ ../llvm/configure
