From: Rod.Bates@wichita.boeing.com (Bates, Rod) Subject: crt0, crt1, _stderr, etc. 20 Aug 1998 06:20:57 -0700 Message-ID: <6C7E2A10BB01D111929500400B406DDEE63919.cygnus.gnu-win32@xch-wch-02.ks.boeing.com> Mime-Version: 1.0 Content-Type: text/plain To: "'gnu-win32@cygnus.com'" Can anyone tell me more about what crt1 and crt0 are? Apparently, there was a crt1.o included in earlier cygwin releases, perhaps 18. It defines, among other things, _stderr, _stdin, and -stdout. B19 seems to have replaced it with crt0.o, which eliminates these. crt0.o looks like a replacement for crt1.o, because they both define _mainCRTStartup. The respective versions of gcc include these respective files in the ld command they issue, without being asked by the issuer of the gcc command. In B19, I looked systematically through all *.o and lib*.a files and found no _stderr defined anywhere. - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
