Hi, I am trying to compile my code with the -fast flag that includes the ipo (with ifort v. 17). The compilation proceeds until linking, throws a bunch of warnings and then stall forever.
This is the way I compile
ifort -c -fast -g -qopenmp -lz -lhdf5 -lhdf5_fortran -lhdf5_hl -I../../src/include radiate_utils.f90 (... + all compilation of all other src files) xiar crs ../../build//ed_2.1-opt.a allometry.o radiate_utils.o (... + all other object files) xiar: executing 'ar' ifort -o ../../build//ed_2.1-opt edmain.o -fast -g -qopenmp -lz -lhdf5 -lhdf5_fortran -lhdf5_hl -I../../src/include ../../build//ed_2.1-opt.a -lz -lhdf5 -lhdf5_fortran -lhdf5_hl ipo: warning #11021: unresolved H5Dget_offset Referenced in libhdf5_fortran.a(H5Dff.o) ipo: warning #11021: unresolved H5Sget_regular_hyperslab Referenced in libhdf5_fortran.a(H5Sff.o) ipo: warning #11021: unresolved H5Sis_regular_hyperslab Referenced in libhdf5_fortran.a(H5Sff.o) ipo: warning #11021: unresolved H5Acreate2 Referenced in libhdf5_fortran.a(H5Aff.o) Referenced in libhdf5_fortran.a(H5Af.o)
And the warnings go on for a while. The compilation is never terminated (I let it run for 3 h when without -ipo it takes around 15 min)
