Hi to All,
I have an error in my makefile which is like this:
objects = hello.o tpl2doc.o
hello : $(objects)
gcc -o hello $(objects) -L /usr/bin/gcc -lstdc++
gcc -o tpl2doc $(objects) -L /usr/bin/gcc -lstdc++
$(objects) : hello.cpp tpldoc.cpp
gcc -c hello.cpp
gcc -c tpl2doc.cpp
all :
${MAKE} hello
PHONY : clean
clean :
-del hello.exe $(objects)
-del tpl2doc.exe $(objects)
I did not find documentation how to write a good makefile for eclipse for
more than one cpp file. Can somebody point out my error, or provide a URL
with info?
Any Help will be gratly appreciated !

Thanks for the answer !
This is my first encounter with non-automaticly generated makefile, so it
was very helpfull. I am using linux, but got the makefile from windows FAQ
for CDT
(none available for linux) so that why is: del hello.exe :) my mistake.
