[cfe-dev] Trying to use CLang / CLang Static Analyzer under Windows XP SP3 32-bit

[TP]

I'm trying to get CLang to run so that I can try out the CLang Static Analyzer.

I followed the instructions given in the "Using Visual Studio" section
of http://clang.llvm.org/get_started.html.

The ALL_BUILD Project built fine in Visual Studio 2008.

But when I try the first example I get:

>clang t.c
clang: error: unable to execute command: program not executable
clang: error: assembler command failed due to signal 1 (use -v to see
invocation)

>clang -v t.c

I don't really want to use gcc (I happen to have cygwin installed, but
gcc is called gcc-3.exe or gcc-4.exe in cygwin\bin.)

I notice that the examples use the -cc1 option so I tried that:

>clang -cc1 t.c

5 errors generated.

__int64 is a builtin VC++ keyword so it's not surprising that CLang
doesn't understand it.

but:

>clang -cc1 -D__int64=int t.c

doesn't produce any output?

>clang -cc1 -D__int64=int -v t.c

No .exe is produced?

Taking a look at C:\llvm\tools\clang\tools\scan-build\scan-build

I gather that it's a perl script. Any chance this is going to work
with cygwin perl (or better yet ActiveState Perl), assuming I figure
out the clang issues?
