Re: [autoconf] Problems Configuring (C Compiler cannot produce executables)

[suzuki toshiya]

I think your set of CFLAGS makes GCC disabled to make a simple
executables like "hello world". So I wonder why you want autoconf
to "fix" the result caused by your CFLAGS. For generic CFLAGS,
you must set CFLAGS that the compiler can make an executable
successfully. You gave CFLAGS that the compiler cannot make
an executable.

Also I've checked the discussion on GCC bugzilla; Andrew Pinski
mentioned automake, but I don't think he recommends a method using
"CFLAGS=blahblahblah ./configure". I guess he recommends to write
configure.am & Makefile.am to insert non-generic & special flags
in the compiling for shared object.

Anyway, you didn't clarified how such special flags are required,
and the coverages of the objects to be compiled with the special
flags, so nobody will be able to the answer to be used immediately.
