<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Andreas,<br>
<br>
"-lgfortran" appears neither in the Makefile of my module nor in the Makefile of the source folder, where my .cc file is located.<br>
Instead, I can find it the DUNE-FEM Makefile, under FCLIBS.<br>
<div><br>
What could I do?<br>

If you search your Makefile for lgfortran does anything turn up and what does it say?<br>

Hi all,<br>
<br>
thanks for the suggestions. Now DUNE recognises the presence of UMFPACK.<br>
<br>
I have just an additional question, since it seems in the linking phase there's a library missing.<br>
Precisely, while building my own module, I get this error:<br>
<br>
/usr/local/lib/libumfpack.a(umfpack_gn_tictoc.o): In function `umfpack_tic':<br>
umfpack_tictoc.c:(.text+0x5): undefined reference to `SuiteSparse_time'<br>
/usr/local/lib/libumfpack.a(umfpack_gn_tictoc.o): In function `umfpack_toc':<br>

xerbla.f:(.text+0x87): undefined reference to `_gfortran_stop_string'<br>
collect2: ld returned 1 exit status<br>
<br>
<div>Googling on other forums, I discovered that it's probably due to the missing inclusion "-lgfortran".<br>
So, following Martin's previous tip, I noticed that in ./configure --help of dune-fem there is the possibility of putting:<br>
<br>
LIBS=-lgfortran<br>
<br>
I put this additional flag in the config.opts I'm using to build my own module ... but it didn't work. Is my command correct? If it's not, where do I have to insert it?<br>
<br>
Thanks for your help!<br>
<br>
Andrea<br>

Hi everyone,<br>
<br>
I have a small problem with UMFPACK.<br>
I'd like to use it to make a comparison with a CG approach, in the specific problem I'm solving.<br>
<br>
When I build my own module, the list of components found is the following :<br>
<br>
dune-common.............: version 2.2.0<br>
dune-fem................: version 1.3.0<br>
dune-geometry...........: version 2.2.0<br>
dune-grid...............: version 2.2.0<br>
dune-istl...............: version 2.2.0<br>
dune-localfunctions.....: version 2.2.0<br>
ALBERTA.................: version 3.0<br>
ALUGrid.................: version 1.50 (parallel)<br>
.<br>
.<br>
.<br>
UMFPACK.................: no<br>
psurface................: yes<br>
<br>
while instead UMFPACK is correctly installed; there is /usr/local/include/umfpack.h and the other libraries.<br>
I tried to modify the Makefile.am, but it didn't work.<br>
<br>
Any ideas about how making DUNE recognise the presence of UMFPACK?<br>
<br>
Many thanks,<br>
<br>
Andrea<br>
