Error when compiling simple LLVM example with Mingw

Question

I'm trying to learn about LLVM API working on Windows, I have installed LLVM 3.6 (llvm tools, clang, etc) successfully, have Mingw and I'm trying to compile this example.

both commmands work on my environment:

clang -c -emit-llvm test.c -o test.ll
llc -march=cpp test.ll -o test.cpp

but when trying to compile this new test.cpp file I got:

C:\Users\Alex\Desktop>clang test.cpp `llvm-config --cxxflags --ldflags --libs core` -o test
clang.exe: error: unsupported option '--cxxflags'
clang.exe: error: unsupported option '--ldflags'
clang.exe: error: unsupported option '--libs'
clang.exe: error: no such file or directory: '`llvm-config'
clang.exe: error: no such file or directory: 'core`'

Any idea? I'm very newbie using LLVM.

It looks like you are using Windows' cmd.exe as your shell, (i.e. command interpreter), but you are attempting to invoke the clang command using a Unix Bourne shell syntax, (the back-tick quoted llvm-config command substitution), which cmd.exe simply doesn't understand.

If you want to use this command syntax, then you'd better find a more capable shell than cmd.exe; perhaps try MSYS or cygwin.
