[Ipopt] IPOpt: configure fails

[Paul van Hoven]

I downloaded IPOpt and put it into the following directory:

/Users/toom/Downloads/CoinIpopt

To get BLAS,LAPACK and HSL I did as on the webpage described, i.e.

$IPOPTDIR/ThirdParty/Blas/get.BLAS

and
$IPOPTDIR/ThirdParty/Lapack/get.Lapack

and I registered and downloaded HSL ma27ad.f and mc19ad.f and put it 
into the ThirdParty/HSL dir.

Okay then I created
mkdir $IPOPTDIR/build
cd $IPOPTDIR/build

In the build dir I executed
$IPOPTDIR/configure

If I do so I get the following error message:
...
checking for Fortran libraries of gfortran...  -lcrt1.10.5.o 
-L/usr/local/gfortran/lib/gcc/i386-apple-darwin8.10.1/4.5.0 
-L/usr/local/gfortran/lib/gcc/i386-apple-darwin8.10.1/4.5.0/../../.. 
-lgfortran -lgcc_s.10.5 -lSystem
checking for dummy main to link with Fortran libraries... unknown
configure: error: linking to Fortran libraries from C fails
See `config.log' for more details.
configure: error: /bin/sh 
'/Users/toom/Downloads/CoinIpopt/ThirdParty/Blas/configure' failed for 
ThirdParty/Blas

Okay, then I downloaded BLAS from the BLAS-Webpage and compiled it 
myself independently of IPOPT. So I called configure again this time with
$IPOPTDIR/configure --with-blas=/usr/local/lib/BLAS

Now, I got the following error
...
checking for Fortran libraries of gfortran...  -lcrt1.10.5.o 
-L/usr/local/gfortran/lib/gcc/i386-apple-darwin8.10.1/4.5.0 
-L/usr/local/gfortran/lib/gcc/i386-apple-darwin8.10.1/4.5.0/../../.. 
-lgfortran -lgcc_s.10.5 -lSystem

configure: error: linking to Fortran libraries from C fails
See `config.log' for more details.
configure: error: /bin/sh '../../../ThirdParty/Lapack/configure' failed 
for ThirdParty/Lapack


Therefore I also downloaded Lapack and compiled it independently of 
Ipopt and called configure again this way
$IPOPTDIR/configure --with-blas=/usr/local/lib/BLAS 
--with-lapack=/usr/local/lib/LAPACK

But suprisingly I get again the same error this time on HSL:
checking for Fortran libraries of gfortran...  -lcrt1.10.5.o 
-L/usr/local/gfortran/lib/gcc/i386-apple-darwin8.10.1/4.5.0 
-L/usr/local/gfortran/lib/gcc/i386-apple-darwin8.10.1/4.5.0/../../.. 
-lgfortran -lgcc_s.10.5 -lSystem
checking for dummy main to link with Fortran libraries... unknown
configure: error: linking to Fortran libraries from C fails
See `config.log' for more details.
configure: error: /bin/sh '../../../ThirdParty/HSL/configure' failed for 
ThirdParty/HSL


Well, I don't know how to go on now?
I do not understand this configure error and it seems to me very odd 
that it is always the same error on three different software modules 
although I'm able to compile the stuff (at least BLAS and Lapack) myself 
without any errors and including it into Ipopt. I'm using Mac OS X 10.6 
with gfortran version 4.5.0 and gcc version 4.2.1.
