14Note: It is YOUR RESPONSIBILITY to ensure that you are entitled to

18If you are working under Unix/Linux-like system and you have `wget'
19installed, you can downloaded the required source code for MUMPS
20by executing the included script `get.Mumps' in this directory.
21
22Note, however, that the script might not be looking for the most recent
23version of Mumps, and it might fail if it tries to download an outdated
24one.  In that case, please check the Mumps home page for the most recent
25version number and change the definition of the mumps_ver variable at the
26beginning of the get.Mumps script.
27
28If you don't have wget available, follow those instructions:
29
30Check the Mumps home page for the most recent version number (say, 4.9).
31You may then download
32
33http://mumps.enseeiht.fr/MUMPS_4.9.tar.gz (or try
34http://graal.ens-lyon.fr/MUMPS/MUMPS_4.9.tar.gz if first URL doesn't work)
35
36and unpack it in this directory:
37
38gunzip MUMPS_4.9.tar.gz
39tar xf MUMPS_4.9.tar
40
41Then, rename the MUMPS_4.9 directory just to be MUMPS:
42
43mv MUMPS_4.9 MUMPS
44
45Further, you may apply a patch that fixes problems with matrices of size 1:
46
47patch -p0 < mumps.patch

50Additional instructions for building with Msys and MinGW
51**********************************************************************
52
53If you are trying to build Mumps in Microsoft Windows using the MSys shell
54environment and gnu fortran compilers, you will first need to install the
55MinGW gcc 4.2 technology preview in order obtain a Fortran 95 compliant
56Fortran compiler. GCC 4.2 is available here:
57
58http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=241304
59
60You need to install the gcc-core, gcc-g++, and gcc-gfortran packages.
61Note the executable names in the gcc packages have the suffix "sjlj" and will
62not be found by the configuration script of whatever project you are trying to
63build, so you must either (1) change their names by deleting the suffix
64(beware that if you do this, you may create a conflict with other version of
65gcc already installed) or (2) configure with
66
67./configure CC=gcc-sjlj CXX=g++-sjlj F77=gfortran-sjlj
