Dear developers,
I have some questions in compiling and runing libMesh,
1, How can I configure a debugging version of libmesh? It seems there is not
such an option when configure -h, I added "--with-debugging=yes" to the
configure command as I did for PETSc, it seems that this can generate a debug
verion of libmesh, but I am not sure.
2, It outputs an error when I install libmesh: "attempted static link with
libstdc++.so", how can I link this lib correctly?
It seems that adding "--enable-shared" does not work.
Currently I just delete libstdc++.so and add "-lstdc++", but too many objects
need to link with this lib, can I handle this by changing something in
configure or Makefile?
3, I configure with the following options, for the particularity of our
machine, I deleted libstdc++.so and add "-lstdc++", and remove "-lgcc_s" when
linking, the ex2 in examples/systems_of_equations outputs error:
***Memory allocation for gkmcore failed.
This error occurs in Build_square(); I have debug it with gdb, as shown in the
attached file "gdb_output.txt".
My configure options are:
./configure \
CC=mpicc FC=mpif90 CXX=mpiCC AR=swar RANLIB=swranlib \
--prefix=/home/export/online1/systest/swsiat/luoli/libmesh-0.9.3/install-debug \
--enable-shared \
--enable-blocked-storage \
--enable-perflog \
--enable-parmesh \
--with-debugging=yes \
--with-dof-id-bytes=8 \
--host=alpha \
--disable-gzstreams \
--disable-tetgen \
--disable-eigen \
--disable-fparser \
--disable-libHilbert \
--disable-nanoflann \
--disable-sfcurves \
--disable-gmv \
--disable-nemesis \
--disable-laspack \
--disable-triangle \
--disable-tbb
The attached are some related files in libmesh.
Thank you very much!
