cross compile bluez 4.40 for ARM

["Marcin Kijewski " <marcin.kijewski@pruftechnik.com.pl>]

Hello,

I have been trying to cross compile bluez 4.40 on ARM processor.

I configured bluez 4.40 by writing:
$ ./configure --host=arm-linux

Configuration seems to be ok.

Then I tried to make the library:
$ make

During compilation attempt I got following error:
(...)
arm-linux-gcc -DHAVE_CONFIG_H -I. -I.. -finline-functions
-fgcse-after-reload -funswitch-loops -funroll-loops -Wall -O2
-D_FORTIFY_SOURCE=2 -D_FORTIFY_SOURCE=2 -MT libsbc_la-sbc.lo -MD -MP -MF
.deps/libsbc_la-sbc.Tpo -c sbc.c  -fPIC -DPIC -o .libs/libsbc_la-sbc.o
cc1: unrecognized option `-fgcse-after-reload'
cc1: unrecognized option `-funswitch-loops'
make[2]: *** [libsbc_la-sbc.lo] Error 1
make[2]: Leaving directory `/projects/bluetooth/bluez-4.40/sbc'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/projects/bluetooth/bluez-4.40'
make: *** [all] Error 2

I tried to remove `-fgcse-after-reload' and `-funswitch-loops' from
"Makefile", "Makefile.in" and " Makefile.am" files.
In this case I got following error:
(...)
arm-linux-gcc -Wall -O2 -D_FORTIFY_SOURCE=2 -D_FORTIFY_SOURCE=2 -o sbcinfo

I use arm compiler version 3.2.1

Can anybody help me ?
Should I use arm-compiler newer than 3.2.1 ?

Best Regards,
