Re: [arm-gnu] Is arm-2009q1-203-arm-none-linux-gnueabi version support for ARM architecture v7(armv7)

Thanks  for reply,

No problem. Please tell me what modifications i need to do ?

I have tried by giving "--with-arch=armv7-a" in gcc configuration and I
built successfully,but i don't know that was correct or not. It is mentioned
at http://gcc.gnu.org/install/configure.html .

But ,after that modification,If I build any application ,without/with giving
any extra flags(i.e -macrh=XXX),and if see the File Attributes ,it is always
showing same thing.

Is it means that It is always building for architect armv7-a ?
