Note-1: you can see what variable to preset by looking at configure.ac, line 1455: 1452 ## Now actually test to see if we can create large files after we've 1453 ## checked for any needed defines. 1454 AC_MSG_CHECKING([if large (64-bit) files are supported on this system.]) 1455 AC_CACHE_VAL([hdf5_cv_have_lfs], 1456 [AC_TRY_RUN([ [...] Note-2: I used 'HDF5' as a prefix, assuming the package is named 'hdf5' in Buildroot.
