[Usbpicprog-technical] firmware-0.4.2 Linker Error - section '.code_usb9.o' can not fit the section

Hello everyone,

i am fun of pic microcontrollers and the project usbpicprog took my breath
and i am looking deep into it.

Because i had experience on the microchip usb stack, i put focus on the
firmware part of the project (i.e. firmware-0.4.2), selectively the
usbpicprog part of the firmware.

As the project is made in piklab i tried building it but it was not
successful. Here is the output i get

*MPLINK 4.37, Linker *
*Copyright (c) 1998-2010 Microchip Technology Inc. *
*Error - section '.code_usb9.o' can not fit the section. Section
'.code_usb9.o' length=0x000002e6 *
*Errors : 1*

after that i looked in to the map file successfully created before error
occured and here is an excerpt from it

*      page     0x082a     0x7fff               .cinit     0x082a     0x001a
*
*                                             .code_prog.o     0x0844
0x5d6a*
*                                     .code_prog_lolvl.o     0x65ae
0x0dc6*
*                                               .code_upp.o     0x7374
0x0ada*
*  *
it seems the object file prog.o from source code prog.c was very large (i.e.
size 0x5d6a) and when the linker tried puting everything together, there was
no space left in memory
and it makes sence to understand the problem that way. For completness, here
are comand line compiler and linker arguments

Next i moved to the MPLAB IDE to see if the problem was with piklab and here
is the output result i get

The above listing shows that there is difference in content between
comparable files with in the two IDE's (Piklab and MPLAB).

My question is that i know this program is a working system and for some
reason which i don't understand now, it is not working. Making the program
small only for selective pic ranges could have solved the problem. But i
don't think that is the reason behind this. Could you please help me
understand why i am having such difficulty?

kindly regards,
michael
