Hi,

I want to eliminate empty initialization functions in code generated by RTW embedded coder (see example below). Any hint on how to eliminate these empty initialization function are wellcome.

Thanks
Klaus

Example:
Given a simple Simulink model (say "ADD.mdl") with following diagram:

Two inputs driving a Sum block, the sum block driving an outport block:
In1 ---- (SumBlock) ----- Out1
In1 -----/

Further given a simple Simulink model (say "TEST_ADD" using two model blocks referencing the ADD.mdl.

Then the RTW embedded coder, generates following code:
ADD.c:
...
/* Model initialize function */
void mr_ADD_initialize(void)
{
/* (no initialization code required) */
}

void TEST_ADD_initialize(void)
{
...
/* Model Initialize fcn for ModelReference Block: '<Root>/Model' */
mr_ADD_initialize();

/* Model Initialize fcn for ModelReference Block: '<Root>/Model1' */
mr_ADD_initialize();
}

Hi,
version of tools and RTW target used would probably help people understand better what are you trying to do.
It may be worth checking Start/BlockInit function options.
Although dead code like that should be optimized-out by the compiler, that looks a bit funny anyway, to say the least , as standard generated code for a Simulink built-in block.
