From: wjb AT bbt DOT com (Bill J. Buie) Subject: pointer dereferenced to incomplete type 29 Sep 1997 11:37:02 -0700 Message-ID: <199709291759.NAA19225.cygnus.gnu-win32@sith.bbt.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit To: gnu-win32 AT cygnus DOT com Can anyone tell me what the error message on the subject line means? The strange thing about the error is that when I tried to put together a minimal program to illustrate it, my minimal program compiled and ran perfectly. But in the context of a very large program I am getting the error message in the subject line, and the compile fails. Here is the minimal program, which works: #include #include static struct tm * getlt() { time_t date; (void) time((long *)(&date)); return(localtime(&date)); } main() { struct tm *workaround; int number; workaround = getlt(); number = workaround->tm_year; printf("year = %d\n", number); } In the context of the large program, the line where I set number equal to workaround->tm_year produces the error. If details help, I am running the Cygwin beta 18 release on a windows 95 machine with 16MB RAM. The large application which fails is nethack 3.2.1, the rogue-like game program. The source file I am choking on is hacklib.c. I ran the file through the preprocessor to make sure I wasn't getting bitten by the large number of #defines, and the source the preprocessor kicks out is what I am expecting. People on this list who have played with the nethack source may notice that the source line in hacklib.c is really return ( 1900 + getlt()->tm_year); but I wanted to break the expression up so I could see where the the error is coming from. When the minimal program worked, I replaced the one line above with workaround = getlt(); number = workaround->tm_year; return(number); but that still produced the error. I'd prefer that responses be mailed to wjb AT bbt DOT com. If enough people ask, I'll summarize what I discover. Thanks, --Bill - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
