Re: [Getfem-users] compilation and computation issues

Hi Kostas,

Many thank for your prompt and effective support.

Well, I have to recognize that I simply followed the instructions on 
http://download.gna.org/getfem/html/homepage/userdoc/install.html which 
does not mention the debian repos. Is there a more detailed page about 
GetFEM++ installation?

Anyway, I will definitely need the parallelization, so... :)

Sadly, '''./configure --with-pic --enable-mumps 
--with-mumps="-lsmumps_seq -ldmumps_seq -lcmumps_seq -lzmumps_seq 
-lpord_seq"''' leads to the same error: '''configure: error: The 
function smumps_c couldn't be found in the provided MUMPS libraries.'''...

4.1.1

Sure.

Arf, same error, sorry.

OK. I think I succeed in compiling (g++ -I./getfem -I./getfem/src 
-I/usr/local/include -DGMM_USES_BLAS -DGMM_USES_LAPACK -O3 -c -o 
$(src).o $(src).cc). But not in linking (g++ 
-l./getfem/src/libs/libgetfem.a -rdynamic -lsmumps -ldmumps -lcmumps 
-lzmumps -lmuparser -lm -lblas -llapack -o $(src).o $(src)). Any idea?

Thanks again,
Martin.
