OK, I understand that. I installed the latest version R11B-5 on target system, made an erlang installation erts/bin folder copy put releases and lib folder from the release I made run my boot script it was made with R11B and it seems like libraries from R11B are not compatible with R11B-5 I receive the following crash:

<br><br>{error_logger,{{2007,6,25},{0,34,39}},"~s~n",["beam/beam_load.c(1148): Error loading function erl_ddll:module_info/1: op int_code_end: :\n  exported function loaded_drivers/0 redefines BIF\n"]}

{"Kernel pid terminated",application_controller,"{application_start_failure,kernel,{shutdown,{kernel,start,[normal,[]]}}}"} So I must always have the same OTP version on development and target system? And then what is the reason to redistribute OTP parts with application releases?

<br>Maybe I miss some important part of release handling but at the moment it looks somewhat inconsistent to me.<br><br>Regards,<br>Kirill<br><br><div><span class="gmail_quote">On 6/24/07, <b class="gmail_sendername">Ulf Wiger
