I posted this to gnu.gcc.help, but it seems worth asking on this list as well. Particularly since it was strongly suggested by participants that I read this book. This is on SuSE 9.3. --------------- Forwarded message (begin) Subject: "Formal" solution: parser.y:7: error: `stderr' undeclared (first use in this function) From: Hattuari Date: Sat, 27 Aug 2005 00:16:10 -0400 Newsgroup: gnu.gcc.help I'm going through the Goat Book http://sources.redhat.com/autobook/, and when I followed the instructions on how to build the first example, I received the following message: Fri Aug 26 23:47:43:> make if gcc -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE=\"foonly\" -DVERSION=\"1.0\" -DYYTEXT_POINTER=1 -I. -I. -g -O2 -MT parser.o -MD -MP -MF ".deps/parser.Tpo" -c -o parser.o parser.c; \ then mv -f ".deps/parser.Tpo" ".deps/parser.Po"; else rm -f ".deps/parser.Tpo"; exit 1; fi parser.y: In function `yyerror': parser.y:7: error: `stderr' undeclared (first use in this function) parser.y:7: error: (Each undeclared identifier is reported only once parser.y:7: error: for each function it appears in.) make: *** [parser.o] Error 1 I may (probably can) get this to compile by some trial and error. But that's why I'm reading the Goat Book! I've been using the other method for years, and I decided to start doing things right.

The reason I'm asking is not that I want the program to compile. I don't even know what it does. I want to know the _right_ way to solve these kinds of problems. Any suggestions? -- STH --------------- Forwarded message (end) -- Regards, Steven
