make clean results in No rule to make target clean

Question

I am running Ubuntu 10 04  Whenever I run make clean  I get this       make      No rule to make target  clean    Stop    Here is my makefile   CC   gcc CFLAGS   -g -pedantic -O0 -std gnu99 -m32 -Wall PROGRAMS   digitreversal all     PROGRAMS  digitreversal   digitreversal o          CC    CFLAGS  -o         LDFLAGS   PHONY  clean clean          rm -f   PROGRAMS    o core   Any ideas why its not working   EDIT  It seems like doing   make -f Makefile txt clean   works  Now  is there any setting to change so I don t have to do the -f Makefile txt every time

I suppose you have figured it out by now. The answer is hidden in your first mail itself.

The make command by default looks for makefile, Makefile, and GNUMakefile as the input file and you are having Makefile.txt in your folder. Just remove the file extension (.txt) and it should work.

You have fallen victim to the most common of errors in Makefiles  You always need to put a Tab at the beginning of each command  You ve put spaces before the   CC    CFLAGS  -o         LDFLAGS  and  rm -f   PROGRAMS    o core lines  If you replace them with a Tab  you ll be fine   However  this error doesn t lead to a  No rule to make target      error  That probably means your issue lies beyond your Makefile  Have you checked this is the correct Makefile  as in the one you want to be specifying your commands  Try explicitly passing it as a parameter to make  make -f Makefile and let us know what happens

Check that the file is called GNUMakefile  makefile or Makefile     If it is called anything else  and you don t want to rename it  then try   make -f othermakefilename clean

This works for me  Are you sure you re indenting with tabs   CC   gcc CFLAGS   -g -pedantic -O0 -std gnu99 -m32 -Wall PROGRAMS   digitreversal all     PROGRAMS  digitreversal   digitreversal o      tab   CC    CFLAGS  -o         LDFLAGS    PHONY  clean clean       tab  rm -f   PROGRAMS    o core

It seems your makefile s name is not  Makefile  or  makefile   In case it is different say  abc  try running  make -f abc clean

[c] "make clean" results in "No rule to make target `clean'"
