I used this tutorial to communicate with my erlang port:
http://www.trapexit.org/How_to_use_ei_to_marshal_binary_terms_in_port_programs
However the port seems to crash if three or more floating points values are sent to it. It crashes with return status 0 which suggest that the function read_cmd in the main() fails.
For example:
Code: {load_screen, "Login.layout", 0.0, 1.2, 1} % Works
{load_screen, "Login.layout", 0.0, 1.2, 1.1} % Crash
Any ideas? |

I wasn't even able to get that far. 
On my windows environment calls to read_cmd just block due to reading an incorrect message length.
On a call to port:add(1,2) the passed length is 224 instead of the correct 13 bytes (as determined by size(term_to_binary({add, 1, 2}))).
Hardcoding length=13 enables the first message and reply to get through.
I'm trying this out on Windows so I'm not expecting much shared suffering. 
Anyway... this might somehow be related with flodis problem.
Additional notes:
- I'm using OTP_R13B and building with Visual C++ 2008 Express Edition.
- When building with MinGW the message length is 0 and I get "** exception exit: epipe"
- The code I'm using (without the debug stuff) can be found here:
