AVL 3.32 was created by chavagne jean
Now i am on ubuntu 12.04. I try to get AVL 3.32.
When in AVL/eispack Makefile, i change FC=gfortran ( like this )

FC = gfortran
FLG = -O
EISLIB = eispack.a
AR = ar r
RAN = ranlib

DP =

#- uncomment for double-precision option
DP = -r8


eispack.a: eispack.f
$(FC) -c $(FLG) $(DP) eispack.f
$(AR) $(EISLIB) eispack.o
$(RAN) $(EISLIB)

clean:
/bin/rm *.o *.a

i have this :

(chavagne@chavagne-desktop:~/Avl/eispack$ gedit Makefile
chavagne@chavagne-desktop:~/Avl/eispack$ make
gfortran -c -O -r8 eispack.f
gfortran: erreur: unrecognized option ‘-r8’
make: *** [eispack.a] Erreur 1
chavagne@chavagne-desktop:~/Avl/eispack$

What i have to do?
thanks a lot

Hey friend,

I made a post in UbuntuForums about installing AVL in Ubuntu not to long ago.

ubuntuforums.org/showthread.php?t=1182359

Basically for this specific problem change DP = -r8 to DP = -dbl

thats what worked for me when I was using g77. It may be different for gfortran because its basically the double precision compiler flag. If the -dbl option doesn't work try -fdefault-double-8. I think thats gfortran's double precision flag. For further reference on gfortran flags visit this page: linux.die.net/man/1/gfortran

Or search the gfortran man pages.

Have fun

Hi chav & Eezyville

I ran into the same problem trying to compile avl 3.35 on my ubuntu 14.04 (trusty).

I made a post in UbuntuForums about installing AVL in Ubuntu not to long ago


I did read it thoroughly. However some of the compiler command (e.g. -dbl) are "outdated".
I tried to work around it without any luck. It compiles "successfully", but running AVL I get the output:

Any tips, updates on that tutorial?



Correction: running AVL with an input file works! without an input I get the above mentioned error.
