I’ve tried to compile simple Hello_world on Linux with gnuarm gcc compiler. It’s build successfull , but in the linking stage there are many errors like this:

/cross/arm/gnuarm-3.4.3/bin/…/lib/gcc/arm-elf/3.4.3/…/…/…/…/arm-elf/bin/ld: ERROR: /cross/arm/src/gnuarm-3.4.3/bin/…/lib/gcc/arm-elf/3.4.3/…/…/…/…/arm-elf/lib/thumb/interwork/libg.a(atoi.o) uses hardware FP, whereas gcc_Hello_World_B.elf uses software FP

After some googling , I think the problem is incompatibility between current version of gnuarm /3.4.3/ and gcc_wmadl_3.3.3.1.0.lib , gcc_wmopenat_3.5.1.0.0.lib .

Wich version of arm-elf-gcc I must use? Or may be the problem isn’t in the compiler version but in some flags supplyed to compiler/linker ?
