From: Wolfgang Bangerth To: gcc-gnats@gcc.gnu.org Cc: Subject: Re: c++/4225: bad reference in an object file caused by the include method Date: Fri, 15 Nov 2002 20:04:43 -0600 (CST) Presently (i.e. at the 3.2.1 stage), the documentation says: `CPATH' `C_INCLUDE_PATH' `CPLUS_INCLUDE_PATH' `OBJC_INCLUDE_PATH' [...] `CPATH' specifies a list of directories to be searched as if specified with `-I', but after any paths given with `-I' options on the command line. The environment variable is used regardless of which language is being preprocessed. The remaining environment variables apply only when preprocessing the particular language indicated. Each specifies a list of directories to be searched as if specified with `-isystem', but after any paths given with `-isystem' options on the command line. I.e., only the part that -isystem implies extern "C" on some systems is now missing. Or at least I could not find it anywhere -isystem is mentioned.
