Safely handling Igor32bit extension and procedure with Igor64bit

Hello all,
Using IgorPro8.

I have an extension  `analyzer` in a directory placed under Igor Extensions.

I have two independent ipf files (GUI_1.ipf and GUI_2.ipf) which make a panel, and they call the function in the Extension.

For user, I would like to place them in a safe and simple manner to one of the procedure folders, so that these panels can be used.
All is fine with 32bit IgorPro, but things break with 64bit.

With 64bit, i see `Function Compilation Error` since at initial compile Igor64 sees the function defined in the extension (which is 32bit).

How to place these procedure files safely.


1.) I tried with a `caller.ipf` file  seeking to try selective include :

---custom_ipfs/
       | - GUI_2.ipf 
       | - GUI_1.ipf

---IgorProcedures
   | - caller.ipf

In this case, the functions in the `GUI_1.ipf` and `GUI_2.ipf` are not loaded.

Content of `caller.ipf`is shown below :

#if !defined(IGOR64BIT)
 
    #include "./../custom_ipfs/GUI_2"
 
    #include "./../custom_ipfs/GUI_1"
 
#endif

2.) and also with another case with custom_ipf folder inside IgorProcedures

---IgorProcedures
   | - caller.ipf
   | - custom_ipfs/
           | - GUI_2.ipf
           | - GUI_1.ipf

 

Content of `caller.ipf`is shown below :

#if !defined(IGOR64BIT)
 
    #include "custom_ipfs/GUI_2"
 
    #include "custom_ipfs/GUI_1"
 
#endif

In this case, the functions in the `GUI_1.ipf` and `GUI_2.ipf` are loaded correctly only for 32bit !

Of course, if I place `GUI_1.ipf` and `GUI_2.ipf` in the `Igor Procedures folder`, all is ok with Igor32bit, but Igor64 bit breaks.

Any suggestions.
