[Ipopt] Created shared objects for Ipopt using the Intel compilers

You could try forcing --enable-shared on the configure line. Apparently that 
gets disabled by something, but specifically asking for it may help?

The past

I have previously used the GCC to compile Ipopt on Linux, using the stock 
settings.  I use MUMPS.  When I execute a 'make install', I end up with the 
following in the target lib directory:

libcoinmumps.so -> libcoinmumps.so.1.4.13
libcoinmumps.so.1 -> libcoinmumps.so.1.4.13
libipopt.so -> libipopt.so.1.9.8
libipopt.so.1 -> libipopt.so.1.9.8

I also build the jipopt shared object so I can interface Ipopt from Java.

This all works a treat.  :-)

The present

I’ve recently obtained the Intel C/C++/Fortran compilers (and Intel MKL) and 
I am trying to compile Ipopt with them.  I use the following configure 

CC=icc CXX=icpc F77=ifort 
./configure --with-blas-lib=-lblas --with-blas-incdir=$MKLROOT/include --with-lapack-lib=-llapack 
 --with-lapack-incdir=$MKLROOT/include --prefix=$HOME/ipopt-3.11.8-intel

I can successfully build Ipopt (by running ‘make’) and pass the unit tests 
(by running 'make test’).

However, when I do a ‘make install’, I end up with the following in the 
target lib directory:


I only get static ‘.a’ archive libraries produced, and no ‘.so’ shared 

The question

How can I get the Intel compiler to create shared objects for ipopt (and 

The things tried so far

I tried adding CFLAGS=-fPIC to the configure script to coax it to produce a 
shareable object, but to no effect.

I tried adding LDFLAGS=-shared to the configure script, but it immediately 
fails to configure and reports:

  checking for C compiler default output file name... a.out
  checking whether the C compiler works... configure: error: cannot run C 
compiled programs.

Any advice on compiling Ipopt with the Intel compilers would be greatly
