The error indicated that during configure, HDF5 concluded the sizeof (long) is 8 bytes but when testhdf5 was compiled, sizeof (long) is only 4 bytes. Similar meanings for the other 3 data types.
I think your system has 32bits as the default mode. You changed it to the 64bits object mode by the "export OBJECT_MODE=64 ... configure" but did not do so during the "make" stage. Therefore, xlc continued with the default 32bits mode and generated 32bits mode objects. If you go to the test/ directory and do "file testhdf5", you would find it is actually a 32bits object file, not as a "64-bit XCOFF executable". To "fix" this, you need to have $OBJECT_MODE set to 64 in all stages of configure/make/make check. I have a caution that if this built library is used later to compile other applications, the users must use the same $OBJECT_MODE value of 64, otherwise you will get mixed mode objects. That usually resulted in linking errors. According to the following IBM document, it is advised to use -q64 instead of using OBJECT_MODE=64. http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/index.jsp?topic=/com.ibm.xlf101a.doc/xlfcr/objmode.htm Important note Using OBJECT_MODE to determine the default bit mode can have serious implications if you are not aware of the setting of OBJECT_MODE at the time of invocation. For example, you may not be aware that OBJECT_MODE has been set to 64, and you may unexpectedly obtain 64-bit object files. We strongly urge you to be aware of the setting of OBJECT_MODE at all times and to set OBJECT_MODE yourself to ensure that the compiler is invoked for the correct bit mode. Instead, you can always use the -q32 or -q64 option to specify the bit mode. Therefore, I would advise you to change your configure command to this: export CC=/usr/vac/bin/xlc export CFLAGS=-q64 export FC=/bin/xlf90 export FCFLAGS=-q64 export CPP=/bin/cpp export CXX=/usr/vacpp/bin/xlC export CXXFLAGS=-q64 export AR="ar -X 64" # need to tell ar to use 64bits mode too ./configure --prefix=/gpfs1/home/rajesh/test/hdf5-1.6.10 --with-zlib=/usr/lib --enable-fortran --enable-netcdf-4 --disable-shared Then you can simply run "make", "make check" and "make install". Everything will run in the 64bits mode. Even the installed "h5cc/h5fc/h5c++" will compile and link in the 64bit mode. BTW, I am not sure why you have "--enable-netcdf-4" in the configure command. "--enable-netcdf-4" is NOT a recognized option by the HDF5 configure and is ignored by the configure command. I hope this helps. -Albert THG Developer At 02:04 AM 3/19/2010, you wrote: >Hi HDF users, > >While trying to install HDF5 on AIX5.3 the following error occurred. > >@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ > >============================ >Testing testhdf5 >============================ > testhdf5 Test Log >============================ > >For help use: ./testhdf5 -help >Linked with hdf5 version 1.6 release 10 >Testing -- Configure definitions (config) >Error: sizeof(long) is 4 but H5_SIZEOF_LONG is 8 >Error: sizeof(unsigned long) is 4 but H5_SIZEOF_LONG is 8 >Error: sizeof(size_t) is 4 but H5_SIZEOF_SIZE_T is 8 >Error: sizeof(ssize_t) is 4 but H5_SIZEOF_SSIZE_T is 8 >Testing -- Encode/decode metadata code (metadata) >Testing -- Ternary Search Trees (tst) >Testing -- Memory Heaps (heap) >Testing -- Skip Lists (skiplist) >Testing -- Reference Counted Strings (refstr) >Testing -- Low-Level File I/O (file) >Testing -- Dataspaces (h5s) >Testing -- Dataspace coordinates (coords) > >@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ > >The command I gave is > >export OBJECT_MODE=64 >export CC=/usr/vac/bin/xlc >export FC=/bin/xlf90 >export CPP=/bin/cpp >export CXX=/usr/vacpp/bin/xlC >./configure --prefix=/gpfs1/home/rajesh/test/hdf5-1.6.10 >--with-zlib=/usr/lib --enable-fortran --enable-netcdf-4 >--disable-shared > >Could anyone please help in this regard? > >Thanks, > >Rajesh >Consultant, >('PRITHVI' High Performance Computing System, >Indian Institute of Tropical Meteorology, Pune) >HCL Infosystems Ltd. >Arena 10, Pune Nagar Road, Viman Nagar, Pune > >_______________________________________________ >Hdf-forum is for HDF software users discussion. >[email protected] >http://mail.hdfgroup.org/mailman/listinfo/hdf-forum_hdfgroup.org
