[cross compiling]x86_64 system, compile target i686

////// · 03-31-2011, 01:14 AM

Hello all.

I'm trying to cross compile usb-modeswitch for my other computer that is i686 system with amd athlon xp processor.

Box that I have been using for compiling is x86_64 system.

command that i have been using for compiling the usb-modeswitch is:

Code:

gcc -o usb_modeswitch usb_modeswitch.c -Wall -l usb

How can I specify that I want i686 rather than x86_64 ?

Have you tried using the -m32 or the -mtune=i686 options with gcc? This produces the 32-bit (versus 64-bit) version of the executable.

For example:

Code:

gcc -Wall -m32 -mtune=i686 usb_modeswitch.c -lusb -o usb_modeswitch

At the moment I do not have access to an x64_86 architecture; I will need to wait till I get to work to experiment with the suggestion above.
