    error implementing a timer

    kishan.raithatha

      i have used a timer 32 bit to generate a timer of 1 sec .
      i have kept interrupt type as terminal count.
      set vc1 to 8 ,vc2 to 3 ,cpu clock as vc2 giving me clock of 1 Mhz
      i have set the period to 1000000 which means it should generate an interrupt every 1 sec.
      i have given the output of terminal count to port 0_0 and connected an led to pin 0 of port 0.
      the following is the code i have written

      my psoc designer uses hi tech compiler

      #include          // part specific constants and macros     
      #include "PSoCAPI.h" // PSoC API definitions for all User Modules     
      #include "timer32.h"     
      void interrupt timer32_isr(void);     
      void main()     
      {     
      TIMER32_WritePeriod(0xf4240); //equivalent hex of 1000000     
      TIMER32_WriteCompareValue(0);     
      TIMER32_EnableInt();     
      M8C_EnableGInt;     
      TIMER32_Start();     
      }     
           
           
      void interrupt timer32_isr(void) @0x00 //as i have hitech compiler so used this way instead of using pragma directive     
      {     
      int count=0; //i have connected port 2 pin 0 to an led so it should glow whenever an interrupt gets generated     
      count++;     
      PRT2DR=count;     
      }     
           
            I have added
      ljmp _timer32_isr
      in the file timer32int.asm at the appropriate place
            these are the messages of error i get when i build the program     
      : 0: (500) undefined symbols: (error)     
      _TIMER32_EnableInt(output\timer2.obj) _TIMER32_WritePeriod(output\timer2.obj) _TIMER32_Start(output\timer2.obj) _TIMER32_WriteCompareValue(output\timer2.obj)     
      HI-TECH C PRO compiler averages 40% less code than this Lite mode     
      PRO may reduce your program size by 51 bytes     
                 
      C:\PROGRA~1\CYPRES~1\PSOCDE~1\tools\make: *** [output/timer2.hex] Error 1     
           
      timer2 - 1 error(s) 0 warning(s) 05:13:52     
           
           
           
      i have referred many app notes as well as user module example projects but cant figure out whats wrong .     
      if any one can help??
