-fast compiler option

-fast compiler option

when i use the -fast option to compile and then attempt to run the resulting program i get the message

Fatal Error : This program was not built to run on the processor in your system

do I have to set something somewhere so that the compiler knows what processor type to use or should it do it by itself. I'm using a sonoma machine... might this be a problem?

Thanks for any help you can give

I'm not sure what "sonoma" is. -fast sets -xP, which requires an Intel processor with SSE3 support. I recommend not using -fast, and add the individual switches (as documented) as you need them.

thanks for the advice.
sonoma is the chipset / configuration of the new pentium m s .

Oh, right. I lose track of all these west-coast town names. You can't use -xP on a Pentium M, and hence cannot use -fast either.
