I have installed djgpp on my DOS system for 32 bit code generation in
'C'. My objective is to generate prommable code for an i386 based product.
As I require a core image file, I did the following things.
- avoided usage of 'main' so that gcc will not include '__main_'
- specified 'nostartfiles' & 'nostdlib', since I don't need them
- did incremental linking
- specified entry point, text, data & bss start addr's
- finally used my own strip utility which reads coff file and produces an
an absolute image file (default strip doesn't do this)
At the end of this process I have an image file whose text, data & bss
sizes added up do not match with the image size itself.
I don't need any startup files, code for switching into protected mode.
We have a debugger running on the embedded system which puts the processor
into protected mode and gives control to the application. This application
is what I am trying to generate using the djgpp.
Immediate information reagarding generation of prommable code using
djgpp would be of great help to me.
