[cfe-dev] Building Clang with Visual Studio 2010 Express

[Krunal Rao]

Hi,

I some questions/observations on building Clang v 3.0 (and LLVM 3.0),
unmodified website sources with Visual Studio 2010 Express.

1. I followed the instructions on:
http://clang.llvm.org/get_started.html , installed the required
software (cmake, python, gnuwin32), updated the PATH environmental
variable and launched:
C:\Users\XXX\prj\llvm-3.0\build>cmake -G "Visual Studio 10"
-DCMAKE_INSTALL_PREFIX=C:\Users\XXX\prj\llvm-3.0\llvm-3.0.install
..\llvm-3.0.src
(the result is reported at the end of the e-mail in case it helps).
LVVM.sln is correctly generated.
Opening it with Visual Studio 2010 Express results in a problem: some
projects (Clang executables, Clang libraries, ...) are unavailable as
"Solution Folders are unsupported in this version."
I can still compile clang and ALL_BUILD fine, so it may be worth
adding a notice on the getting started webpage.

2. Building clang and ALL_BUILD did not result in anything being
installed in the directory specified above via DCMAKE_INSTALL_PREFIX.
Is this the expected behaviour?

3. I cannot run the regression test by building clang-test as it
cannot find bash.exe. However bash.exe seems not to be included in
GnuWin32. Should I install it separately? If so a note could be added
to the getting started page.

4. clang.exe cannot find my visual studio headers (I thought this
would happen by default when building Clang as above): trying to
compile a C file which has
#include <math.h>
gives an error (math.h: file not found).
Did I make some mistakes or should I add the Visual Studio headers by
hand via -I ?

Thank you again for all the help.

PS the reason I am compiling Clang with Visual Studio as well is
because the visual debugger helps me a lot with understanding the
working of the code.
