From the config.log: configure:4203: gcc -c -I/scratch/opt/include -I/scratch/opt/include conftest.c >&5 conftest.c:57:17: hdf.h: No such file or directory ... configure: failed program was: ... | #include <hdf.h> and configure:4203: gcc -c -I/scratch/opt/include -I/scratch/opt/include conftest.c >&5 conftest.c:57:21: hdf/hdf.h: No such file or directory ... configure: failed program was: ... | #include <hdf/hdf.h> These commands would have succeeded if /scratch/opt/include/hdf.h or /scratch/opt/include/hdf/hdf.h existed, so it must be elsewhere. What is its exact location? The check for the size of unsigned long fails because: ./conftest: error while loading shared libraries: libhdf5.so.5: cannot open shared object file: No such file or directory This happened because the test for the hdf5 library passed and it was added to LIBS, and the subsequent tests link with it. The error means you are trying to execute a program that was linked to a shared library whose location the dynamic linker is not aware of, i.e. you must add /scratch/opt/lib to LD_LIBRARY_PATH, or to /etc/ld.so.conf, or link with an rpath. You can't put shared libraries in non-standard locations without notifying the dyanmic linker, otherwise it will have no idea where to find the library at runtime.
