Hello Malek: This is the crosstool-ng config file (I followed the config file for the 64-bit alpha cross compiler) for the 32-bit alpha cross compiler available through the M5 page: http://www.cse.usf.edu/~sroy/techres/m5res/xtools/alphaev67-unknown-linux-gnu.ct_config
You may follow it to configure your own build. -Soumyaroop On Fri, Jun 25, 2010 at 1:07 PM, Malek Musleh <malek.mus...@gmail.com> wrote: > Hello, > > I am trying to build an Alpha Cross Compiler using crosstool, but am > able to successfully build it and compile some sample test programs, > but when I try to run it in M5 (Alpha_SE mode) i get an error saying: > > > FATAL: kernel too old > panic: Tried to access unmapped address 0x30. > @ cycle 316500 > > Now I tried compiling this test program using the prebuilt Alpha Cross > Compilers on the M5 Wiki page, and they run just fine in M5.
