[LLVMdev] Compiling llvm and Clang on Linux

[Sitvanit Ruah]

Do I have to recompile from scratch whenever I am changing the
configuration?

It looks like I need to give additional flags  to the configure command.
Anything else I need except CC, CXX and CXXFLAGS?

Do I need any of the following too?
--with-c-include-dirs   Colon separated list of directories clang will
                          search for headers

  --includedir=DIR       C header files [PREFIX/include]

What is the difference between the above two options?

--libdir=DIR           object code libraries [EPREFIX/lib]

Ok, I got. You should install libstdc++44-devel, too.

Please try to install gcc44-c++ and libstdc++44-devel.

Note: gcc44-c++ depends on gcc44, but gcc44-c++ and libstdc++44-devel
are independent each other, at least on my host, CentOS5.
