Hello ,
I am using arm9 based fujitsu card . I have compiled and ported linux-2.6.15
with eldk4.2. I am trying to insert a module in which I am using floating point operations.
While compiling this module , the following errors occur :
*** Warning: "__subdf3" [/export/home1/suchita/bws_linux/bws_menu.ko]
