Hello.
I would like to know if somebody can help me, please. I got to the
part of compiling, but running the tests throws an error which I
haven't been able to figure out. Let me know the information that you
need. Below is the last part of what `make check' tells me. Thanks.
CXXLD dynamic_tas

After some days, I think I'm getting closer. The Makefile for tests uses
libtool, and I was able to link with mpicxx alone with the addition of
-shared. The expanded command from the Makefile for the dynamic_tas
target is:
/bin/sh ../libtool --tag=CXX --mode=link /usr/bin/mpicxx -fPIC
-fopenmp -O3 -march=amdfam10 -mtune=generic -O2 -D_FORTIFY_SOURCE=2 -O3
-std=c++14 -L/usr/lib -L/usr/lib/openmpi
-L/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0
-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -o dynamic_tas
dynamic_tas.o ../src/libgetfem.la -lm -lsmumps -ldmumps -lcmumps
-lzmumps -lqhull -llapack -lmpi_cxx -Wl,-rpath -Wl,/usr/lib -Wl,-rpath
-Wl,/usr/lib/openmpi -Wl,-rpath
-Wl,/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0 -lmpi -lpthread -lmetis
-lsuperlu -lesmumps -lptscotch -lptscotcherr -lscotch -lscotcherr
-lcmumps -ldmumps -lsmumps -lzmumps -lmumps_common -lpord -lblas
-lmetis
(I added some libraries by means of the LIBS environment variable [1]).
By replacing that with this:
/usr/bin/mpicxx -shared -fPIC -fopenmp -O3 -march=amdfam10
-mtune=generic -O2 -D_FORTIFY_SOURCE=2 -O3 -std=c++14 -Wl,-O1
-Wl,--sort-common -Wl,--as-needed -Wl,-z -Wl,relro -Wl,-z -Wl,now -o

-Wl,/usr/lib/openmpi -Wl,-rpath
-Wl,/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0 -L/usr/lib
-L/usr/lib/openmpi -L/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0
-Wl,--enable-new-dtags -lmpi_cxx ../src/.libs/libgetfem.so -lm -lqhull
-llapack -lmpi_cxx -lmpi -lpthread -lsuperlu -lesmumps -lptscotch
-lptscotcherr -lscotch -lscotcherr -lcmumps -ldmumps -lsmumps -lzmumps
-lmumps_common -lpord -lblas -lmetis
, dynamic_tas was successfully created. I will now try and see if I can
apply the same logic to other targets (of the tests/Makefile)
Aaaaand that's the penguin!
