Re: [petsc-dev] Compiling C code with C compiler
There is clang and clang++ - but still they insist on throwing this warning. When I invoke clang++ - I want c++. So I'm not sure whats so ambiguous that they should throw this warning. And what does this depricate mean? That 'clang++ foo.c' will create C code? Then why have both clang and clang++? satish On Mon, 4 Apr 2011, Barry Smith wrote:
configure.log ????
What about passing the compiler option -x C++? Or maybe you are already doing that but I would't know because you didn't send configure.log
It's bad enough when our ignorant users don't send necessary configure.log files but you?

When specifying --with-clanguage=C++ (as required by sieve) all C code (any .c file) is still compiled with the C++ compiler. This behavior is deprecated as clang will warn you:
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated
C is not a subset of C++ and treats structs very differently than C++. This should really be handled correctly but I can't read the conf/rules file no more than I can read Greek.
