[Discuss-gnuradio] Compiler machine compatibility

[Marcus D. Leech]

I have some code that lives on top of Gnu Radio, and I think I'm having 
a code-generation issue with GCC.  The binaries work on all
  my machines, but on a customers machine, it raises an Illegal 
Instruction exception.  I generated the code on a 32-bit Intel Core
  machine, on Fedora 12.  The code is executing on a Pentium-IV class 
machine, on a Fedora 12 installation.  I gather than by default
  GCC will generate code that's optimized for the machine on which the 
compile is happening.  How do distributors of binaries assure
  that the code will execute correctly on older-generation hardware?
