[Lazarus] on ARM Linux ,SoftFloat and EABI issues

[Nataraj S Narayan]

Henry,

Thanks for the suggestions. Will try cross compiling. I cross compile using
"/home/nataraj/arm-2008q1/arm-none-linux-gnueabi-".

Freepascal wiki says to install fpc for the native x86 machine first. 
Then go for fpc-arm version 2.0.4. Which version of fpc should i install 
in native host - 2.2.0 or 2.0.4? Also, for cross compiling 2.0.4 ,how do 
i specify the said cross bin utils ?

regards

Nataraj
