hi,
I have successfully cross compiled bluez-libs for my AT91SAM9260
which has arm926ej-s processor core.
VERSION:Bluez-utils-3.36 and 3.34
Linux-2.6.25
But when i compile Bluez-utils i am facing lot of errors.Inside the
bluez-utils i have read the README file.
It says Bluez-utils needs BISON,FLEX,USBLIBRARY and GCC.
Do i have to cross compile BISON,FLEX for the Bluez-utils to cross compile????
When i configure the bluez-utils without cross compiling bison and flex.
[root@localhost bluez-utils-3.36]# ./configure --host=arm-linux
--prefix=/opt/atmel/devkit-4.1.2-uclibc3/
--libdir=/opt/atmel/devkit-4.1.2-uclibc3/lib
--includedir=/opt/atmel/devkit-4.1.2-uclibc3/include
--with-kernel=/testing3/buildroot/project_build_arm/airbox/linux-2.6.24
it configures well.
But when i type make it gives the error.....
storage.c: In function 'encrypt_link':
storage.c:286: error: 'ENOKEY' undeclared (first use in this function)
storage.c:286: error: (Each undeclared identifier is reported only once
storage.c:286: error: for each function it appears in.)
make[2]: *** [storage.lo] Error 1
make[2]: Leaving directory `/bttesting/bluez-utils-3.36/input'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/bttesting/bluez-utils-3.36'
make: *** [all] Error 2
so i disabled the input option by supplying the key --disable-input.
[root@localhost bluez-utils-3.36]# ./configure --host=arm-linux
--prefix=/opt/atmel/devkit-4.1.2-uclibc3/
--libdir=/opt/atmel/devkit-4.1.2-uclibc3/lib
--includedir=/opt/atmel/devkit-4.1.2-uclibc3/include
--with-kernel=/testing3/buildroot/project_build_arm/airbox/linux-2.6.24
--disable-input.
Then the cross-compiling succeeds.But When i transfer the tools like
hciconfig,hciattach,,,etc to the target and try to execute it says
Segmentation fault.
Hence i thought i should cross compile BISON and FLEX.So i have cross
compiled BISON and FLEX using buildroot.
Again Bluez-libs has compiled properly.
But Bluez-utils failed in the configure step.
[root@localhost bluez-utils-3.36]# ./configure --host=arm-linux
--prefix=/opt/atmel/devkit-4.1.2-uclibc3/
--libdir=/opt/atmel/devkit-4.1.2-uclibc3/lib
--includedir=/opt/atmel/devkit-4.1.2-uclibc3/include
--with-kernel=/testing3/buildroot/project_build_arm/airbox/linux-2.6.24
it says.....

i don't know why it is failing with lex and flex??? .Is there any
patch i should apply to cross compile ?????
Please guide me to solve this error.
Any "How to document" on cross compiling bluez-utils for arm will be
helpful to me...
NOTE: I have exported the CC and other environment variables by using a script.
# source btscript
This is the script file.
#! /bin/bash

export CC=arm-linux-gcc
export CXX=arm-linux-gcc
export LD=arm-linux-ld
