Hi Alexander We should add the following lines to the configure script to check for large file support in the kernel. As the GetDiskFreeSpace gets wrong information regarding the disk space on disks > 2GB. dnl This test must come as early as possible after the compiler configuration dnl tests, because the choice of the file model can (in principle) affect dnl whether functions and headers are available, whether they work, etc. AC_SYS_LARGEFILE CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=${ac_cv_sys_file_offset_bits}" AC_CHECK_SIZEOF(off_t, 64, [ #include <stdio.h> #include <sys/types.h> #include <unistd.h> ]) Thanks Vijay
