LibXC not working (abinit-9.6.2)

Hi all,

I am trying to compile abinit-9.6.2 on a new computer and am having some problems with the configuration. I will try to give as much info about the compilation:

  • compilers: Intel 2021.2, with MPI and MKL
  • libxc-4.2.3
  • xmlf90-1.5.4
  • libpsml-1.1.8
  • fallbacks: hdf5, netcdf, netcdf_fortran, libxc

I am compiling abinit with PSML support. I have just compiled siesta using the same libraries, and it works fine. Abinit seems to be happy with everything, but no matter what I do, it always says LibXC is not working. I tried building the fallback version but still get the same result.

Running with

…/configure --with-config-file=“make.ac9” FC=mpifort CC=mpicc

I have attached my .ac9 file and a log of the configuration below.

I think I have found the problem: From the config.out file you can see that it is not checking if LibXC has fortran support:

checking whether to enable LibXC… yes
checking how LibXC parameters have been set… env
checking for LibXC C preprocessing flags… -I/n/kaxiras_lab/dbennett/psml-libs/include
checking for LibXC C flags… none
checking for LibXC linker flags… none
checking for LibXC library flags… -L/n/kaxiras_lab/dbennett/psml-libs/lib -lxcf90 -lxc
checking whether the LibXC library works… no
checking whether the LibXC library has an old API… no

whereas with e.g. libpsml:

checking whether to enable LibPSML… yes
checking how LibPSML parameters have been set… env
checking for LibPSML C preprocessing flags… none
checking for LibPSML Fortran flags… -I/n/kaxiras_lab/dbennett/psml-libs/include
checking for LibPSML linker flags… none
checking for LibPSML library flags… -L/n/kaxiras_lab/dbennett/psml-libs/lib -lpsml -lxmlf90
checking whether the LibPSML Fortran interface works… yes

it is checking. I compiled it with fortran support, and have both libxc.a and libxcf90.a $ROOT_PSML/lib, but it doesn’t seem to look for the FC Flags.

Any help/advice greatly appreciated!

Dear Daniel,

Can you include the config.log file that was also generated?

Yes, I have attached the config.log file in the original post.

Checking all the mentions of libxc, I found:

sd_libxc_libs=‘-L/n/kaxiras_lab/dbennett/psml-libs/lib -lxcf90 -lxc’
sd_libxc_options=‘required no-fortran warn’

Fortran support is definitely not enabled for libxc. Is there any way to tell configure to enable fortran support? I thought setting LIBXC_FCFLAGS would do that.

For reference, here is the result of ls in $ROOT_PSML/lib:

libpsml.a libxcf03.a libxcf90.a pkgconfig libxc.a libxmlf90.a

So I am pretty sure my libxc has fortran support. I also attach the config.log file for libxc here:

The error happens in the config.log at line 2443:

2445 /n/kaxiras_lab/dbennett/psml-libs/lib/ undefined reference to `psml_die_’

A similar error was raised in a past issue. It seems the psml library might be interfering somehow. Maybe try to seperate the libs and incs of psml from libxc? I’m not familiar with psml. @beuken any idea?

Thanks for catching this! I don’t think I would have found it myself.

I recompiled libxc and libpsml in separate directories but that did not work. Following the issue reported in gitlab, I removed the *.so files from the libpsml library, and then it worked! I guess that prevented dynamic linking between libxc and libpsml?

Strange that this issue doesn’t occur when compiling siesta…

Thanks again,

To clarify things a little bit:

  • LibPSML does not depend on LibXC.
  • ABINIT only requires the C library of LibXC, since it has its own internal C to Fortran interface.

Everything should work fine when using the --with-libxc=/path/to/libxc/install/prefix option, which will take care of the linking details with LibXC.

Yes, I thought it was strange since libpsml does not depend on libxc. I did try using the --with-libxc flag and was having the same problem, although I won’t reproduce the problem now since I finally have abinit compiled and working.

The reason I compiled libxc with fortran support is because it is required for siesta (at least I think it is). In future I will compile separate libraries for both codes.
