Subject:      'make' problem
To: DJGPP mailing list <djgpp AT delorie DOT com>

I encountered a problem with 'make', but it could be just my ignorance...
The thing is, I wrote a generic makefile for my small C++ project, like this:

objs = file1.o file2.o file3.o

.cc.o:
        gcc -x c++ -c ›<

main.exe: ›(objs)
        gcc -o ›@ ›^

file1.o: file1.cc file1.h
file2.o: file2.cc file2.h
file3.o: file3.cc file3.h


Everything worked ok. But when I renamed all .cc files to .cpp and changed
all appearances of .cc in the makefile to .cpp (including .cc.o: ), make
always goes to the link step, even when there are no .o files at all.
Just now some idea struck me -- this must have something to do with
.SUFFIXES, but I thought .cpp was confirmed to be a valid C++ source
file extension, thus make should recognize it. GCC itself recognizes it,
though dumps .cc extension to cc1plus. Anyway, I'll read more make docs
and try the .SUFFIXES stuff at home, but right now if the problem is different
and someone knows the solution, please let me know.
