Compiling the solver "GJH" for AMPL?

[charles...@gmx.net]

Hello,

I'm looking for a way to get the solver GJH for ampl, so that I can
access and evaluate first and second derivatives of my nonlinear
problem.

I downloaded the AMPL solver files from "http://netlib.bell-labs.com/
netlib/ampl/" in a big tarball, and now I'm looking at all those
files... I found the files gjh.c in the subfolder "examples", and also
"README.gjh" which tells me what I can do with gjh in AMPL. So I guess
there already is everything I need in order to get the GJH solver that
I want.

Now, how do I actually create whatever file I need in order to use
GJH? I guess I have to compile something here so that in the end I
have an executable "GJH" that I can put into the same directory as my
AMPL executable, right?

I'm working on a 64 bit Linux openSUSE 10.2 system.

[Vladimir]

In directory "examples" type "make gjh".
On my machine I first had to edit the makefile (the one in the same
directory) and change line 30 to
CFLAGS = -g -fPIC

and also line 45 to
L = -lm -ldl

Regards,
Vladimir

Hi Vladimir,

I tried that and got the following error messages:

And I have no idea why this looks so bad...

without Unix/Linux experience that may be hard to do. Obviously you
need to include certain AMPl header files either by having -I.. or
so in your compile options assuming the files are one level up or by
copying the ones you need into the examples directory.

I see ... I think you have to do the following:

1. go one directory up (called "solvers")
2. rename "makefile.u" to "makefile"
3. type "make" (which should compile amplsolver.a)
4. go to directory "examples"
5. rename "makefile.u" to "makefile" (this should overwrite existing
makefile)
6. edit "makefile" as indicated in the previous post, i.e.
CFLAGS = -g -fPIC
L = -lm -ldl
7. type "make gjh"

Let me know how it goes.

Hi Vladimir, hi Hans,

I followed Vladimir's advice and got the response attached below.

Looking at the output I noticed that -among other things- it complains
about not finding "getstub.h", which is in the directory above, i.e.
in ampl/solvers. I tried to compile "gjh" in the directory ampl/
solvers/examples. Copying the file "getstub.h" into the examples
folder did not solve the problem, instead it complained about new
files that were also missing. I guess it might be looking in the wrong
directory...?

And, yes, I am a complete Linux newbie ...

# cd ampl/solvers
# rename makefile makefile.org
# rename makefile.u makefile
# make (a lot of unintelligible output appeared, and then there
was a new file "amplsolvers.a")
# cd examples/
# rename makefile makefile.org
# rename makefile.u makefile
# edit makefile (I did the changes that Vladimir described)
# make gjh

uz:/home/delix/num_package/GJH package/ampl/solvers/examples #

[Hans Mittelmann]

In the examples directory execute the command:

cc -I.. -o gjh gjh.c ../amplsolver.a -lm -ldl

Hi Hans,

Thanks for the advice! That command worked wundervoll. :-)
