Can't link against system-installed version of MUMPS when building IPOPT 3.8.1

[John Pye]

When attempting to build IPOPT 3.8.1 on Ubuntu Karmic with

./configure --with-mumps-lib=/usr/lib/libdmumps.a --with-mumps-incdir=/usr/include

I get an error

checking if user provides library for mumps... yes
checking whether symbol dmumps_c is available with MUMPS... no
configure: error: Cannot find symbol(s) dmumps_c with MUMPS
configure: error: /bin/bash './configure' failed for Ipopt

According to the IPOPT mailing list, there are bugs in MUMPS >4.8.3; it may be preferable to package against MUMPS 4.9.x.

Not sure if this is still an issue, but it works with

./configure --with-mumps-incdir=/usr/include --with-mumps-lib=-ldmumps

'--with-mumps-lib' expects actual linking flags.

OK I will try that. Have you checked that the resulting IPOPT actually runs correctly... I believe that when IPOPT builds its own copy of MUMPS, some patches are applied to the source code.
