UNIX for Dummies Questions & Answers

That's not completely true... you CAN set FC, CC and so forth, in the Makefile. You should compile it with mpicc or mpif77 or whatever. It will use what values you provide for these variables.

Normally your makefile will look something like this:

Code:

FC=g77
FFLAGS=-O2
MPIFC=mpif77

mpiprog: mpiprog.o

mpiprog.o: mpiprog.f
   $MPIFC $FFLAGS mpiprog.f -o mpiprog.o

thanks for your reply let me inspect my files again, good info but i need more than this, I will try some things you said and post something later to make it more specific. I have a command -I which i think is something like include and this creates the mess in the error message, maybe i should post the error message.the previous post was just a hint from a friend who guessed in general the situation. I also have many makefiles 3 or 4 ,and one other which is probably the top level makefile.

In Gnu make, the top level makefile directives are passed to sub-makefiles anytime you do an Include or something like this:

Code:

target-lib-dir : 
   cd lib-dir; $(MAKE)
