[petsc-users] makefile for compiling multiple sources

[Matthew Overholt]

Hi,

 

I'm just getting started with PETSc and have been able to configure and run
the examples, but as I'm starting to put together a more substantial code
with multiple source files I haven't been able to find or create a makefile
which works and follows PETSc guidelines.

 

I've configured and am building with the Intel compilers and MKL for blas &
lapack, as per the installation example, and with the C++ language.

 

Here's my makefile --------------------------------------

# 

# makefile for femex1 - PETSc/kde/ex1.c adapted for FEA

#

# Usage: make all

#        make clean

#

# PETSc was configured using the Intel Compilers, MKL, and C++

#

CFLAGS        = 

CPPFLAGS     = 

CLFLAGS      = 

LIBFILES      = ${PETSC_KSP_LIB}

TARGET        = femex1

CLEANFILES   = $(TARGET)

 

include ${PETSC_DIR}/lib/petsc/conf/variables

include ${PETSC_DIR}/lib/petsc/conf/rules

 

OBJFILES = femex1.o \

           shapes.o

 

all: $(TARGET)

 

$(TARGET) : $(OBJFILES) $(LIBFILES)

       ${CLINKER} -o $(TARGET) $(OBJFILES) $(LIBFILES)

 

# femex1.cpp has 'main' and PETSc calls

femex1.o: femex1.cpp lists.h shapes.h  chkopts

       ${PETSC_CXXCOMPILE} femex1.cpp

 

# shapes.cpp does not have any PETSc calls

shapes.o: shapes.cpp shapes.h

       icpc -c shapes.cpp

 

And here's the result ------------------------------------

 

[Matt at HPCL1 mycode]$ make all

/opt/petsc/petsc-3.6.3/linux-gnu-intel/bin/mpicxx -c -wd1572 -g  -fPIC
-I/opt/petsc/petsc-3.6.3/include
-I/opt/petsc/petsc-3.6.3/linux-gnu-intel/include      femex1.cpp

icpc -c shapes.cpp

make: *** No rule to make target
`-Wl,-rpath,/opt/petsc/petsc-3.6.3/linux-gnu-intel/lib', needed by `femex1'.
Stop.

 

---------------------------------------------------------------

So it compiles the two sources, but then fails on the linking step.

 

Thanks in advance.
