Hello, I have a custom hardware (AU1100) with kernel 2.4 and an working binary using floats (compiled with gcc 3.3.5). Now I am testing with kernel 2.6. When I use the old binary, float math isn't working anymore. I have to recompile the source with new gcc 4.1.2 but then the new binary is working only on kernel 2.6. Can somebody give me some hints, how to chage settings for kernel 2.6 creation or compiler settings to generate an universal binary. Thanks Uwe
