armv4l-unkown-linux-gcc compiler problem!!

Hi, I am a newbie in the embedded system world. Currently, I got a development board with StrongARm 206MHz CPU. I got the vivi and the cross compiler and prepared to compile a bootloader for my embedded system, However when I run the "make" command

/opt/host/armv4l/bin/armv4l-unknown-linux-gcc -I/root/cheong/gsl/linuette/vivi/i nclude -I/opt/host/armv4l/include/ -Wall -Wstrict-prototypes -O2 -fPIC

-fomit-frame-pointer -mapcs-32 -mshort-load-bytes -msoft-float -c -o init/main.o init

as: unsupported option `-mapcs-32' make: *** [init/main.o] Error 1

I refered to the cross-compiler gcc-2.95.2, it should supported the option '-mapcs-32', so why I got such error?

The version 2.95 ARM GCC is obsolete.

Get a version 3 GCC. The code generation in 2.95 was a hasty kludge and it contains several problems. IIRC, the code was for apcs-32 anyway.

If you're running a Windows host, the generation and setup of GNU cross-tools goes well under Cygwin.

Does your bootloader really need floating point (-msoft-float)?

The position-independent code option is also a little suspect in this context (-mPIC).

Here "info gcc" says that -mapcs-32 is a replacement for -m6 on older gccs. 2.95 is an awfully old gcc. You might try for a newer gcc, or try using the -m6 option.

Is it possible that gcc is invoking the wrong assembler? ('as' is the assembler stage.) Try running your compile with the -v option to see. Maybe gcc is trying to use the native assembler instead of the cross-assembler.
