Building static library of recipe routines

01-29-2009, 10:28 PM
I have purchase CD-ROM of NR v3.0.
It contains Fortran90 routines(older version) also.
These routines have lot of inter-dependencies.
so, i want to build a static/dynamic library of all of them.
I work in linux (openSuSE 10.2).
I tried following way,
#compile all (including utility progs. like nr.f90, nrtype.f90, etc.)
# it generates ".mod" file for many of them.
>gfortran *.f90 -c

#put them into one library archive
> ar crs libnrf90lib.a *.o *.mod

now when i use this lib file with my program to access some
NR routine, it asks for some ".mod" files.
When i put them into the dir. and then it compiles the program.
>gfortran myprog.f90 -l nrf90lib -L /path-to-libfile

pl. help me solve this prob.

>gfortran myprog.f90 -l nrf90lib -L /path-to-libfile

All of the mod files have to be on the Include path.

gfortran myprog.f90 -Ipath_to_directory_containing_mod_files -lnrf90lib -Lpath_to_directory_containing_libnrf90.a

For example: I copied the entire NR distribution to /home/dave/nr3. Fortran 90 NR source files are in /home/dave/nr3/legacy/nr2/f90_210/recipes. I create a static library named "libnr2f90.a" in that directory and I leave the .mod files there also.

I created a program file named z.f90 in /home/dave/nr3/legacy/nr2/f90_210/examples

I created a Makefile in /home/dave/nr3/legacy/nr2/f90_210/examples:

.SUFFIXES: .f90 .o
FORTRAN = gfortran
LIBDIR = ../recipes
INCLUDEDIR = ../recipes
LIB = nr2f90


$(FORTRAN) $< -L$(LIBDIR) -l$(LIB) -o $@


rm -f $(TARGET) $(TARGET).o

Then I just execute "make" from the command line. Here's what I see:

gfortran -I../recipes -c z.f90
gfortran z.o -L../recipes -lnr2f90 -o z

And the executable is created.

Now, suppose I want to compile xzroots.f90
I can modify the TARGET definition in the Makefile, or from the command line I can execute

make TARGET=xzroots

Here's what I see:

gfortran -I../recipes -c xzroots.f90
gfortran xzroots.o -L../recipes -lnr2f90 -o xzroots

And "./xzroots" runs the program.

Of course you can modify the LIB name definition and the LIBDIR and INCLUDEDIR path definitions to be whatever you need for your system. (Absolute paths or paths relative to your project file will work equally well.)

Dear Dave
Thank you very much.
now i got it.
so, if i understand it properly, mod files are very similar
to header files of c/c++.
only diff. being that we dont include them in program file.

thanx again.

...mod files are very similar
to header files of c/c++....That is one way of looking at it. The "USE" statement tells the compiler to look for some stuff in some "mod" file somewhere. The command line "-I" switch tells the compiler where to look for the "mod" files.

Or some such thing.

Not sure if this is the best place to post this but I am having a problem creating a static library of the recipes on mac os x 10.6. I am using gfortran and have run the make file but when I execute make lib I get an error saying

/usr/bin/ranlib: file: libnr.a(nr.o) has no symbols
/usr/bin/ranlib: file: libnr.a(nrtype.o) has no symbols

and end up with a libnr.a file of 2.1mb. Does anyone have any idea what I'm doing wrong?

The start of my make file reads:
.SUFFIXES: .reslt .res .out .o .f90 .for .f
# Numerical Recipes makefile for Fortran 90
# Edit this to be correct on your system

Not sure if this is the best place to postIt seems to be as good a place as any.

problem creating a static libraryThe Original Poster of this thread said that he already had created a static library, so I didn't bother telling how I created one.

on mac os x 10.6.

Well, I can show the Makefile that I used to create a static library on my Centos 5.5 Linux workstations (GNU gfortran version 4.1.2 and GNU make version 3.81). Maybe it will help, but YMMV (Your Mileage May Vary).

Anyhow, this is one approach for NR Fortran 90 version 2.1. Put this in the recipes directory and run "make" from there. (See Footnote.)

.SUFFIXES: .f90 .o

FORTRAN = gfortran
# Put nrtype, nrutil, nr first
# Then put the files that have modules defined
# Then put all of the other source files
# Note that xlinbcg.f90 was supplied in the examples
# directory, but module xlinbcg_data from that file
# is needed for asolve.f90 and atimes.f90, so it copies
# xlinbcg.f90 here and uses it as part of the source file
# list.

My response to the Original Post showed a Makefile that I use to link with the library. These days I use the slightly more modern form

%.o: %.f90

instead of the old-fashioned


(But the results are the same.)



Maybe it seems like I'm doing it the "hard way," but I like to know exactly what goes into my library file and how it gets there. In my case, the size of libnr2f90.a was something like 1.6 MBytes. You can run nm -s or objdump -f to verify the contents of the library file.
