32bit. Turns out that, if number of *rows* in *internal_transition_table* islarge it throws this error. After replacing with *transition_table* it compiles large number of *rows*. Any particular reason?? On Fri, Oct 4, 2013 at 6:14 PM, Klaim - Joël Lamotte <mjklaim@gmail.com>wrote:

Which compiler is it? Also, which build mode? 32bit or 64bit?

Hello,

I am using boost Meta - state machine. I have 19 state which is compiling ok. but whn i incease the number of state transition in Transition table(using internal_transition_table) i get >this error: "Virtual Memory Exhausted: cannot allocate memory"

Has anyone has face the same problem??

Regards Rahul

Hi, It's hard to answer without seeing code. How large is the compiler process? At the limit of what a 32-bit system can allocate? And which compiler are you using?

I have tried using transition_table inside a state and its is not possible to have transition. But i am able to compile. If i use internal_transition_table then the maximum number of rows > is limited to around 120.

Well, internal_transition_table is more expensive than a simple transition_table because MSM is forced to create rows in the transition table for all rows in the internal_ version. 120 is pretty large, it's enough to kill many compilers, first to go would be VC and older version of gcc. If I get the code I can try it on onther compilers or on a 64-bit system. MSM is still quite hard on the compilers and with 120 transitions, I bet you're at the limit of what the system can allocate.
