Hello,

I am trying to set up a Makefile so that I may compile my c++ code using 
DJGPP and MingW into sub-folders, using the environment variable ENV to 
hold the target name

I first thought I could use the VPATH variable and use 'make -C $(ENV)' 
but, after changing into the sub-folder, it always reports:
    *** No targets specified and no makefile found. Stop

I then remove VPATH and tried the vpath variable:
    vpath %.o $(ENV)

and to specify $(ENV) as part of the -o for compiling and linking:
    .cxx.o:
        $(CC) $(CXXFLAGS) -c $< -o $(ENV)/$@
    %.exe: %.o
        $(CC) $(LDFLAGS) -o $(ENV)/$@ $^ $(LOADLIBS)

This compiles all the .o but does not link the .exe in the first 
invocation of make - none of the .o files have the $(ENV) path.
A second invocation of make will call the linker

Can someone give me assistance with this?

April
