I had problem when compiling my hdf write test project in debug mode: > it crashed with error R6034 It took a while but I found out that this happened becouse I had no szip and zlib debug libraries. So I decided to compile my own version of HDF5 library without szip and zlib libraries. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! This binary distribution of HDF5 is compiled by Mikko Niemelä (University of Oulu) on PC running Windows XP using Visual Studio 2008. Built with following options: -- C/C++ libraries, both static and shared -- SZIP and ZLIB (Gzip) DISABLED !!! -- Static and shared HDF5 tools !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
