Clang built, but again there are 268 clang-test

Have you built clang and run the

Is there anyone in clang

<p class="MsoNormal">Yaron,<br>
<br>
Thanks for your
response.
Unfortunately this
did not resolve the
issue.<br>
<br>
I am extremely
confused and unable
to find the correct
combination to build
libclang.dll and
libclang.dll.a for
for Windows 32-bit
and Windows 64-bit.
There are multiple
sets of directions
and sadly they do
not agree with each
other.
<br>
<br>
I have tried the -G
"Unix MakeFiles",
<span
style="font-family:"Helvetica","sans-serif"">
-G "MSYS
Makefiles" , and
-G "Mingw
Makefiles" </span>so
far. All three
produce the dll and
.a files.
<br>
<br>
a) However, the
build requires hand
changes to two
makefiles due to
backslash problems.
I am unable to find
out if this is a
know bug or not.<br>
<br>
b) The build
crashes around 98%
saying it is unable
to find the
libclang-exports. If
I restart the build
it completes
successfully. This
feels like a
dependency order
problem.
<br>
<br>
c) After
building, no matter
which cmake setup I
use, the "make
clang-test" fails
with just over 260
Unexpected Failures.
Is there any known
problem with these
tests on Windows?<br>
<br>
<br>
I need a version of
clang which is not
compiled with MSVC.
I have tried gcc
4.7.2 and gcc 4.8.1
(MinGW-W64). I am
using Python 2.7.9.
CMake version 3.2.2
and GNU Make
3.82.90.
<br>
<br>
On some sets of the
instructions there
is an indication I
need to install
compiler-rt, which I
have not done. This
was not required for
the very simple
build on Debian
which worked
flawlessly. Is this
required?
<br>
<br>
I was told clang is
being supported on
Windows so I
strongly believe
some combination of
what I am doing is
not correct and I am
out of ideas. I am
grateful for any
suggestions, ideas,
or information about
how to build clang
and have this work.
