From the Lite-C workshop 24 does this sample give the problem?
Code:
///////////////////////////////
#include <acknex.h>
#include <default.c>

///////////////////////////////

var rotation_speed = 0.1;

function mother_earth()
{ 
	while (1)
	{ 
		my.pan += rotation_speed * time_step;
		wait (1); 
	}
}

function main()
{
	vec_set(sky_color,vector(1, 1, 1));	// black sky
	level_load ("");
	wait (2); // wait until the level is loaded
	ent_create("earth.mdl", vector(400, 0, 0), mother_earth);
}


Or this example inside the Workshop
Code:
////////////////////////////////////////////////////////////////////////////
// small.c - small lite-C example
////////////////////////////////////////////////////////////////////////////
#include <acknex.h> // include these predefined, needed files in our project
#include <default.c>
////////////////////////////////////////////////////////////////////////////
void main()
{
    // Load the level named "small.hmp"
    level_load("small.hmp");
    // Wait for 3 frames, until the level is loaded
    wait (3); 
    // Now create the "earth.mdl" model at x = 10, y = 20, z = 30 in our 3D world
    ent_create("earth.mdl", vector(10, 20, 30), NULL);
    // NULL tells the engine that the model doesn't have to do anything
}
