octave:1> x = 1:10; octave:2> save ("-hdf5","testout.hdf5") Warning! ***HDF5 library version mismatched error*** The HDF5 header files used to compile this application do not match the version used by the HDF5 library to which this application is linked. Data corruption or segmentation faults may occur if the application continues. This can happen when an application was compiled by one version of HDF5 but linked with a different version of static or shared HDF5 library. You should recompile the application or check your shared library related settings such as 'LD_LIBRARY_PATH'. You can, at your own risk, disable this warning by setting the environment variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'. Setting it to 2 or higher will suppress the warning messages totally. Headers are 1.8.16, library is 1.8.17 SUMMARY OF THE HDF5 CONFIGURATION ================================= General Information: ------------------- HDF5 Version: 1.8.17 Configured on: Sun May 15 08:43:52 CEST 2016 Configured by: marco@GE-MATZERI-EU Configure mode: production Host system: x86_64-unknown-cygwin Uname information: CYGWIN_NT-6.1 GE-MATZERI-EU 2.5.1(0.297/5/3) 2016-04-21 22:14 x86_64 Cygwin Byte sex: little-endian Libraries: shared Installation point: /usr Compiling Options: ------------------ Compilation Mode: production C Compiler: /usr/bin/gcc CFLAGS: -ggdb -O2 -pipe -Wimplicit-function-declaration -fdebug-prefix-map=/cygdrive/e/cyg_pub/devel/hdf5/hdf5-1.8.17-1.x86_64/build=/usr/src/debug/hdf5-1.8.17-1 -fdebug-prefix-map=/cygdrive/e/cyg_pub/devel/hdf5/hdf5-1.8.17-1.x86_64/src/hdf5-1.8.17=/usr/src/debug/hdf5-1.8.17-1 H5_CFLAGS: AM_CFLAGS: CPPFLAGS: H5_CPPFLAGS: -DNDEBUG -UH5_DEBUG_API AM_CPPFLAGS: Shared C Library: yes Static C Library: no Statically Linked Executables: no LDFLAGS: H5_LDFLAGS: -no-undefined AM_LDFLAGS: Extra libraries: -lz -ldl -lm Archiver: ar Ranlib: ranlib Debugged Packages: API Tracing: no Languages: ---------- Fortran: no C++: yes C++ Compiler: /usr/bin/g++ C++ Flags: -ggdb -O2 -pipe -fdebug-prefix-map=/cygdrive/e/cyg_pub/devel/hdf5/hdf5-1.8.17-1.x86_64/build=/usr/src/debug/hdf5-1.8.17-1 -fdebug-prefix-map=/cygdrive/e/cyg_pub/devel/hdf5/hdf5-1.8.17-1.x86_64/src/hdf5-1.8.17=/usr/src/debug/hdf5-1.8.17-1 H5 C++ Flags: AM C++ Flags: Shared C++ Library: yes Static C++ Library: no Features: --------- Parallel HDF5: no High Level library: yes Threadsafety: no Default API Mapping: v18 With Deprecated Public Symbols: yes I/O filters (external): deflate(zlib) MPE: no Direct VFD: no dmalloc: no Clear file buffers before write: yes Using memory checker: no Function Stack Tracing: no Strict File Format Checks: no Optimization Instrumentation: no Bye... panic: Aborted -- stopping myself... attempting to save variables to 'octave-workspace'... save to 'octave-workspace' complete Aborted (core dumped) gavin@anders ~ $
