I installed the cdt in the eclipse.So now I can process the c++ file.I
programeded a simple c++ file:hello world! And I programed a make file .This
is the code:

objects = hello.o

hello : $(objects)
gcc -o hello $(objects) -L /usr/bin
$(objects) : hello.cpp
gcc -c hello.cpp

all :
${MAKE} hello

…PHONY : clean
clean :
-del hello.exe $(objects)

I use the command : /usr/bin/make -f makefile to compile the makefile.

But there is a error :***commands commence before first target.Stop.
How to solve the problem? Help!

I.E. Not Spaces!

make is very picky about the use of tabs, eg

hello : $(objects)
gcc -o hello $(objects) -L /usr/bin
^
there MUST be a tab character here.

You should have “-g” if you want to debug.
And has the other posters noted.

My two cents:

-del hello.exe - this is wrong, should be hello.
-L /usr/bin doesn’t make sense - there are neither .so nor .a libraries in
/usr/bin.
