[U-Boot-Users] [ARM] Compiling U-Boot with the CodeSourcery ARM toolchain - undefined reference to 'raise'

FYI

The list arm-gnu@codesourcery.com has a thread starting:

" I tried 2007Q3 to compile u-boot for arm926ejs, but i got the following error "undefined reference to `raise". Is it correctable? "

with the (probable) conclusion:

" I don't think you need to go that far. Uboot is a stand-alone application; raise() is an OS call on Linux that raises a signal (in this case SIGFPE, with the subcode of division-by-zero). What you need here is a suitable definition of __div0 for your division function (__div0 is called if the user attempts to divide by zero). In most bare-metal apps like uboot, you simply need a definition of __div0 that returns 0 rather than throwing an exception. The implementation of __div0 that comes with the arm-none-eabi build of the tools should do that. Perhaps you should use that version of the compiler for building uboot, not the arm-none-linux-gnueabi version. "
