[ECOS] Difference between generated binary files from Linux and Windows (cygwin)

Hi,

On a Linux environment, when I compile an eCos application with powerpc-eabi-gcc
(version 3.2.2), I don't obtain the same binary files (.bin or .srec) than on a
Cygwin (Windows) environment.

Why the same version of powerpc-eabi-gcc on a different development environment
doesn't make the same binary ?

Thanks,

Emmanuel Coullien

What sort of differences?  Are they consistent, or do they change from 
build to build?

The two toolchains should produce identical code so long as the same
options are used.

How do the files differ? You can use objdump on the .elf files to see
exactly where the code generation has changed.
