My experiences in installing IPOPT on Mac OS X
Related question: State of the Mac OS in Scientific Computing and HPC. A significant number of software packages in computational science are written in Fortran, and Fortran isn't going away. A Fortran compiler is also required to build other software packages (one notable example being SciPy). However, Mac OS X does not include a Fortran compiler.
by Peter CarbonettoDept. of Computer Science
University of British Columbia
IPOPT is asoftware package for solving nonlinear objectives subject to nonlinearconstraints. It uses primal-dual interior pointmethodology. Importantly, it is open source.
After a great deal of time and trouble, I managed to get in workingon my laptop which is running the Mac OS X operating system.1 In the following, I detail myexperiences in installing the IPOPT package.
Succinctly put, the configure script did not work for IPOPT, so Ihad to install everything from scratch. While this was really quite alabourous process, I didn't know any other way of installing thepackage. On the bright side, I learned a lot about compiling fortranand C++, and linking object code, libraries and executables

1. Installing the Fortran compiler
The first problem I encounter is that I do not have a Fortran 77compiler installed on my machine. I do have the GNU C and C++compilers installed on my computer already (the programsgcc
and g++
), but the Fortran 77 compiler isalso needed to compile the BLAS, LAPACK and HSL routines. A lot ofpeople are upset that the GNU Fortran compiler g77
wasnot included with the AppleDeveloper Tools because installing it ourselves causes many extraheadaches. But we'll have to make do.
There are several ways I can install a Fortran compiler. One is bydownloading GNU Fortran compiler from the High Performance Computingwebpage. Another route is to install g77
via Fink. Instead, I'm going tofollow the route that gives me the most control: I will download andbuild the entire GNUCompiler Collection (GCC), then put the necessary files in theappropriate places. Even though this route is considerably morecomplicated, it will allow me to ensure that I have the correctversion of the compiler. You see, since I'm running Mac OS X 10.3.9 Ialready have gcc
3.3 installed on my computer in the/usr/bin/
directory. (It is easy to check the version bytyping gcc --version
.) It is important that the compilersI'm using all belong from the same collection otherwise it is verylikely that I will undercover linking errors. I've decided todownload GCC 3.3.6 from my local university FTP mirror.
It is crucial that I do not follow the default installationfor GCC, because I may end up overwriting important files. The GCCinstallation instructions advise the same thing. Suppose that I'vechosen to install to the directorygcc-install
--prefix=gcc-install
configure
script. After following the correctinstallation steps and waiting a couple hours for the entire packageto be built, I now have a whole bunch of files and subdirectories ingcc-install
In the end, I had installed the following files:
2. Building the BLAS, LAPACK and HSL libraries
Now that I have a Fortran 77 compiler installed on my system, Iproceed to build the libraries needed by IPOPT from scratch. First, Idownload the latest BLAS and LAPACK tarballs from the Netlib FTP repository. The BLASpackage just consists of a bunch of Fortran files. I compile each ofthe individual files into object code, starting with the filecaxpy.f
:
This creates an object file caxpy.o
. The rest of thefiles are compiled similarly. If you want to produce a shared library,you will want to include the -fPIC
option. Also, I'venoticed that the -fexceptions
option should not be usedas it causes linking errors down the road. Once I've compiled all theFortran code, I create a static library via the following commands:
I create the LAPACK library in precisely the same fashion, with thesame options passed to g77
. The only difference is thatthe files in the LAPACK tarball are strewn about in varioussubdirectories. In brief, the quickest way to build the LAPACK libraryis to use the existing Makefile and type
at the command prompt with lapack/SRC
being thecurrent directory. Before we do that, however, we need to modify a fewof the options passed to the Makefile. First, I movelapack/make.inc.example
tolapack/make.inc
. Looking at this file, I see that itspecifies among other things the program used to compile the Fortrancode, which is g77
, exactly as I want it. Near the bottomof this text file, I change the variable LAPACKLIB
to
Now, I can type the make
command in theSRC
subdirectory and it should proceed to automaticallycreate the library (this takes about ten minutes on my computer).

Lastly, I create a library with the HSL subroutines. Afterfollowing the instructions in the IPOPT document for downloading thecode from the HSL Archive, I create the library with the followingcommands:
Now I'm ready to create the IPOPT library.
3. Building the IPOPT library
I will elect not to follow the standard installation instructions(since they didn't work) and instead build the IPOPT library byhand. Basically, I'm going to follow almost the same steps as I didbefore. The trickiest part is that I need to modify the fileIpopt/inc/config_ipopt.h
manually; the configure scriptdoes this automatically. My file looked like
Next, I compile the C and C++ source files into object files. Forinstance, a create the object file IpAdaptiveMuUpdate.o
with the command
where ipopt-include-dir
is the directory containingall the .h
and .hpp
header files. And soon. Once I've compiled all the source files, I create the staticlibrary with the commands
Note that in most cases it will not make sense to archiveall the object files into the library. For instance, youshould not include IpMa57TSolverInterface.o
unless youhave downloaded that solver (I didn't). By the same token, I didn'tinclude the code for interfacing with the AMPL and CUTEr.
4. Testing the installation with an example
I can't be positive that we built the libraries correctly withouttrying to run a program that actually uses IPOPT. I try the Hock andSchittkowski nonlinear programming test example no. 71, which isincluded with the IPOPT tarball. After copying all the staticlibraries to libhome
, I compile and link the codewith the following sequence of commands:
Fortran 77 Download Mac Download
Now have a program which is executed by typing./hs071
. Note that the order in which I included theobject files and libraries in the above lines is important. Theg2c
library helps us link the Fortran object code to theC++ object code (recall that I placed this library in/usr/lib
).
Footnotes
1 More precisely, I'm using MacOS X version 10.3.9 (Panther), and I have a PowerPC G4 processor. Youmay find that the steps I follow apply to your system, even if itisn't the same process or version of the operating system.
The purpose of the GNU Fortran (GFortran) project is todevelop the Fortran compiler front end and run-time librariesfor GCC, the GNU Compiler Collection. GFortran development is partof the GNU Project. We seek to bringfree number crunching to a broad spectrum of platforms and users.
In particular, the project wishes to reach users of theFortran language, be it in the scientific community, education, or commercial environments. The GFortran compiler is fully compliantwith the Fortran 95 Standard and includes legacy F77 support.In addition, a significant number of Fortran 2003 and Fortran 2008features are implemented. Please give it a try. If you encounter problems,contact us at the mailing list or file a problem report.

Fortran 77 Format
GFortran development follows the open development process. We dothis to attract a diverse team of developers and to ensure that GFortranworks on multiple architectures and diverse environments. We always needmore help. If you are interested in participating, please contact us atfortran@gcc.gnu.org.(Also check out our mailing lists page.)
The Wiki and Getting the Compiler
For additional info on GFortran developments, you may find theGFortran wiki useful. Anyone may contribute information to the wiki. (Neither copyrightpaperwork nor a patch review process is required.)
The GNU Project is about providing source code for its programs. For convenience, a number of people regularly build binaries for different platforms. Links to these can be found at the wiki. Most of the binary executables are the latest development snapshots of GFortran and areprovided to encourage testing. We also want new users, from studentsto masters of the art of Fortran, to try GFortran.It really is a great compiler!
Project Objectives
We strive to provide a high quality Fortran compiler that workswell on a variety of native targets. This means:

Conformance to Fortran standards, primarily Fortran 95, 2003,and 2008
Performance of executables and computational accuracy
Reasonable compile speed and cross compilation capability
Good diagnostics and debugging features
Legacy code support where practical.
Extensions in GNU Fortran
The initial goal of the GNU Fortran Project was construction of aFortran 95 compiler that complies with the ISO Fortran 95 ProgrammingLanguage standard [ISO/IEC 1539-1:1997(E)]. We are now well intoF2003 and F2008 features.The GFortranwiki and our bug trackerlist features under development or yet to be implemented. Compilercapability is quite extensive and includes nearly all g77 features.We highly encourage users to move from g77, which is no longermaintained, and start taking advantage of GFortran's modern features.Legacy g77 code will compile fine in almost all cases.
Status of Compiler and Run-time Library
We regularly update thestatusof the front end and run-time library development.
Contributing
We encourage everyone to contribute changes and help test GNU Fortran. GNU Fortran is developed onthe mainline of GCC and has been part of the compiler collectionsince the 4.0.0 release.

Contributions will be reviewed by at least one of the followingpeople:
- Paul Brook
- Steven Bosscher
- Bud Davis
- Jerry DeLisle
- Toon Moene
- Tobias Schlueter
- Janne Blomqvist
- Steve Kargl
- Thomas Koenig
- Paul Thomas
- Janus Weil
- Daniel Kraft
- Daniel Franke
Under the rules specified below:
- All normalrequirements for patch submission (assignment of copyright tothe FSF, testing, ChangeLog entries, etc) still apply, andreviewers should ensure that these have been met before approvingchanges.
- Approval should be necessary forpatches which don't fall under the obvious rule. So, with the approver listput in place, everybody (except maintainers) should still seek approval for his/her patches. We have found the mutual peer review process really works well.
- Patches should only be reviewed bypeople who know the affected parts of the compiler. (i.e. thereviewer has to be sure he/she knows stuff well enough to make agood judgment.)
- Large/complicated patches shouldstill go by one of our maintainers, or team consensus.
- We are all reasonable people, and nobody is working underemployer pressure or needs an ego-boost badly, so in general weassume that no-one deliberately does anything stupid :-)
