Compiler Flag -fast

[dundar yilmaz]

Hi,

I want to use dislin libraries with my project. I successfully compiled my code by linking libraries.

However when I want to use -fast flag (processor dependent optimization for intel) it gives a linker error.

Which optimization level used to create dislin libraries? Can I recompile it from source code (if available) with

-fast flag ?

Hi Dundar,

The Dislin libraries for Intel Fortran are compiled on Linux with gcc and the optimization option -O2,
on Windows with ifort and MS Visual C++ with the option -Ox. The ifort option -fast should work on
Linux, but not on Windows. The -fast option contains the option /Qipo for interprocedural optimizations
between files, which is not compatible to the Dislin libraries for Intel Fortran on Windows. You have to
use the option -Ox or -O3 instead of -fast, or to disable the option /Qipo.

Best regards,

Helmut

Hi Helmut

When I compile with -fast flag ifort on a linux machine I got these warnings:

ipo: warning #11021: unresolved glReadBuffer

        Referenced in libdislin.a(qqwini.o)

ipo: warning #11021: unresolved glClearColor

        Referenced in libdislin.a(qqwini.o)

ipo: warning #11021: unresolved XMapWindow

        Referenced in libdislin.a(qqwini.o)

and the compiler crashes.

Hi,

I have another problem but this is kinda different than the previous one.

My code is running on a node of a cluster system. It is not possible to share DISLIN libraries with nodes. Thus I need 

to compile it with static libraries instead of shared.

In my source code folder

SRC/

   DISLIN/ dislin installed here

   Version_007/ main source code here

So to compile I use the following make file (trimmed out unrelavant parts :

 fcc = ifort

### fcc = /opt/intel/Compiler/11.1/072/bin/intel64/ifort

 SUFFX= -c 

 FLAGS= -O3 -finline-limit=100 -inline-forceinline  -unroll=30  -openmp 

 

 FLAGDEBUG= -debug

#-check all -traceback

 suffix=-c $(FLAGS)

#-O3  -debug -g ## -vec-report2  ##-parallel -par-report2

 version= _007

 mkllibs=-L~/opt/intel/composer_xe_2011_sp1.8.273/mkl/lib/intel64/ \

         -liomp5 -lpthread ##-lmkl_intel_thread -lmkl_intel_lp64

 Charpak=-L./ charpak_lib.a dislin-10.2.a

 DISLININC=-I../DISLIN/ifc/

 objects = mathlibs.o structures_module.o smtables_module.o    \

           main.o global_variables.o parameters_module.o \

           elementmap_module.o energy_module.o opt_parent_module.o \

           opt_simplexb_module.o cost_functions_module.o mask_module.o\

           analysis_module.o user_interface_module.o opt_montecarlo_module.o graphics.o

#para_type.o types.o enforcefunctions.o inout.o \

           initializers.o analysis.o opt.o main.o 

#enforce.o  analysis.o  inout.o main.o \

                md.o opt.o tests.o initializers.o

EXE=oops

EXE_debug=oops_debug

EXEFLAG=  $(FLAGS) -o 

#debug: FLAGS +=-g -debug

#debug: $(EXE)

DATE            =`date `

all:$(EXE)

$(EXE):$(objects)

        $(fcc) $(EXEFLAG) $@ $(objects) $(mkllibs) $(Charpak) $(DISLININC)

        cp oops ../../Test

 graphics.o :parameters_module.o graphics_module$(version).f90

        $(fcc) $(suffix) $(DISLININC) graphics_module$(version).f90 -o graphics.o

and I use 

------

use dislin

-------

statement at graphics module.

Receive the following type of errors

qw_unx.c:(.text+0x134ed): undefined reference to `XAllocColorCells'

dislin-10.2.a(qqwini.o): In function `qqwini':

qqw_unx.c:(.text+0x135fe): undefined reference to `XOpenDisplay'

qqw_unx.c:(.text+0x13612): undefined reference to `XVendorRelease'

qqw_unx.c:(.text+0x13631): undefined reference to `XDefaultScreenOfDisplay'

qqw_unx.c:(.text+0x1363d): undefined reference to `XDefaultScreen'

I think I am not linking libraries properly.

Any idea what I am doing wrong?

it seems that you have forgotten to link with the X11 and OpenGL libraries, which are
necessary if you are linking with the static library of Dislin. The following was working
for me with ifort 11.1 on a SUSE 64-bit system:

      ifort -c -fast -I$DISLIN/ifc  exa_f90.f90
      ifort exa_f90.o  -L$DISLIN -ldislin                  linking with the shareable Dislin library

or
      ifort -c -fast -I$DISLIN/ifc  exa_f90.f90
      ifort exa_f90.o $DISLIN/libdislin.a -L/usr/X11R6/lib64 -lGL -lXm -lXt -lX11

for linking with the static library of Dislin.

Best regards,

Helmut
