cannot find -ladios2f

[martin-g]

Hello!

I am adding ADIOS2 to OpenHPC and the Fortran tests fail to build for some unknown to me reason.

I am trying to build https://github.com/ornladios/ADIOS2/blob/v2.8.3/examples/hello/bpReader/helloBPReaderHeatMap3D.F90 (renamed as scalars_read.F90) and I get the following error at linkage time:

...
make  arrays_write arrays_read scalars_write scalars_read
  CXX      arrays_write.o
  CXXLD    arrays_write
  CXX      arrays_read.o
  CXXLD    arrays_read
  PPFC     scalars_write.o
  FCLD     scalars_write
/usr/bin/ld: cannot find -ladios2f

  PPFC     scalars_read.o
  FCLD     scalars_read
/usr/bin/ld: cannot find -ladios2f
collect2: error: ld returned 1 exit status
...

The used compiler options are:

CXX compiler.................... : /opt/ohpc/pub/mpi/openmpi4-gnu12/4.1.4/bin/mpic++
CXX compiler flags.............. : -DADIOS2_USE_MPI -I/opt/ohpc/pub/libs/gnu12/openmpi4/adios2/2.8.3/include -g -O2

LIBS............................ : -ladios2_cxx11 -ladios2_cxx11_mpi -ladios2_fortran -ladios2_fortran_mpi -lm -lhdf5

I don't understand where -ladios2f comes from! There is no libadios2f.so in the lib folder:

Any pointers ?
Thank you!

I think the question is where the -ladios2f is coming from. That name is no longer used, but rather -ladios2_fortran or -ladios2_fortran_mpi. But really, if you look at the cmake spec in that examples directory, the dependency is on adios2::fortran, which is a symbolic name at the CMake level. That change to be a symbolic name was apparently made in 2020. Maybe there is another older install of adios on your system that is somehow confusing the examples build? It's hard to guess exactly...

Thanks for your answer, @eisenhauer !

To clarify: I am not building the examples but I have copied few of them to OpenHPC/tests/libs/adios2/tests folder to use them as smoke tests and I build them with OpenHPC's autoconf/make setup. I.e. I manually setup the CXXFLAGS/FCFLAGS/LDFLAGS and LIBS:

CXXFLAGS="-DADIOS2_USE_MPI -I${ADIOS2_INC} ${CXXFLAGS}"
FCFLAGS="-DADIOS2_USE_MPI -I${ADIOS2_INC}/adios2/fortran ${FCFLAGS}"
LDFLAGS="-L${HDF5_LIB} -L${ADIOS2_LIB}"
LIBS="-ladios2_cxx11 -ladios2_cxx11_mpi -ladios2_fortran -ladios2_fortran_mpi -lm -lhdf5"

and the test execution prints the actual values:

CXX compiler.................... : /opt/ohpc/pub/mpi/openmpi4-gnu12/4.1.4/bin/mpic++
CXX compiler flags.............. : -DADIOS2_USE_MPI -I/opt/ohpc/pub/libs/gnu12/openmpi4/adios2/2.8.3/include -g -O2

ADIOS2 is installed from a .rpm build with this .spec

I don't see where -ladios2f comes from ...

[eisenhauer]

It looks like -ladios2f might come from OpenHPC tests/libs/adios2/tests/Makefile.am...

Thank you!
Not sure how all my grepping missed it!
Fixed with https://github.com/openhpc/ohpc/pull/1642/files#diff-cba093f1b666e3a86deb8320639a380d2a643e2b9ab33471f6c4abac4da34510R16
