Hi,
Here are two patches to allow Cygwin to build. ‘edis’ is disabled as it will not build with dynamic libraries, and libprofile also does not build on Cygwin. If anyone using Cygwin wants there functionality they will have to fix them

I think, it will be much better to have something like
"have_dynamic_linking" variable inside make harness and use it
accordingly....

I applied your patch for runtime, and applied a different patch to tools. Thanks.

LLVM-GGC builds and installs okay using gcc-4.2.4 minimum. ‘make check’ runs okay too.
clang fails with a dynamic linking problem.
Aaron
What's the problem? and if you would please file a bug that would be awesome 
thanks!

Eric,
Neither Cygwin nor MinGW support Dynamic Linking. I am getting the following :-
llvm[4]: Compiling CIndexer.cpp for Debug build (PIC)
/home/ang/svn/llvm-clang/tools/clang/tools/CIndex/CIndexer.cpp: In member functi
on ‘const llvm::sys::Path& CIndexer::getClangPath()’:

I am hoping I can just not build the indexer and will see if I can get a patch together first for 2.7 before submitting a bug report if I have to.

Okay here’s a patch to no build the CIndexer on Cygwin and MinGW :-

CygMinGW.patch (399 Bytes)
Hi Aaron, did you actually test that this patch fixes the problem you’re seeing?
-Chris
Yes, its been tested on Cygwin, and disables CIndex and its test on Cygwin and MinGW. CIndex makes programatic usage of DL_open so cannot be used on either platform. There maybe a better solution as I just hacked this to get Clang to build on Cygwin…
Aaron
I committed a fixed patch as r97892
