OffTopic: Need help with Make on Linux
Fellow Hackers: I am trying to run this *very* simple make file, but I cannot get the bloody thing to work. Not sure what I am missing. I have tried a number of things like including *cc -c main.c* to see if I could force make to recognize the rules/dependencies. No luck. Any help would be appreciated? Below is a copy of: * Makefile * Error listings. * Directory Listing * Versions of make, uname -a --------------------------------------------------------------------- [root@dba xml]# make build make: *** No rule to make target `main.o', needed by `build'. Stop. [root@dba xml]# make main.o make: *** No rule to make target `main.c', needed by `main.o'.

Try: make -f /dev/null main If that doesn't work, then there's something very weird going on. You don't have MAKEFLAGS=-r or MAKEFLAGS=r set in your environment, do you? And the lines that contain the cc compiler invocations really do start with a tab and not with, say, 4 spaces? Assuming, then, that /dev/null makes an adequate makefile, we probably want to start with "mv Makefile junk.Makefile". Next, create a new Makefile which reads: main: Now try make again. It should be OK. If that fails, then you'd better report back... If that works, then you can try adding a build rule before it: build: main main: If that doesn't work, report back. If it works, then change the last line to two lines: main: main.o $(CC) -o $@ main.o Some gibberish there using standard make rules. There's a tab at the start of the $(CC) line; that is *critical*. One or more spaces is an error, though usually make will report a problem with the makefile. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v1.00.PC1 -- see http://www.perl.com/CPAN #include <disclaimer.h>
