samba - Oct 2010 - Cross-compile Samba 3.5.6 with STLinux 2.3 (SH4 CPU)

I need to generate a minimal Samba working in a SH4 cpu in a STLinux 2.3
environment. The goal is to have very very simple Samba server running in a
STLinux environment. STLinux Kernel has included the CIFS support.

Really I'm a newbie in Samba cross-compilation. And obviously I've
problems :-(
Any help will be appreciated. Thanks :-)


1) First of all I've set some env vars:
export PREFIX="sh4-linux"
export CC="${PREFIX}-gcc"
export CXX="${PREFIX}-g++"
export LD="${PREFIX}-ld"
export NM="${PREFIX}-nm -B"
export AR="${PREFIX}-ar"
export RANLIB="${PREFIX}-ranlib"
export LN_S="ln -s"
export CFLAGS="-g -O2"
export PKG_CONFIG_PATH=/opt/STM/STLinux-2.3/devkit/sh4/target/usr/lib/pkgconfig
export LD_LIBRARY_PATH=/opt/STM/STLinux-2.3/devkit/sh4/lib
export LDFLAGS="-L/opt/STM/STLinux-2.3/devkit/sh4/lib
-L/opt/STM/STLinux-2.3/devkit/sh4/lib/gcc/sh4-linux/4.2.4"
export CPPFLAGS="-I/opt/STM/STLinux-2.3/devkit/sh4/include
-I/opt/STM/STLinux-2.3/devkit/sh4/lib/gcc/sh4-linux/4.2.4/include
-I/opt/STM/STLinux-2.3/devkit/sh4/lib/gcc/sh4-linux/4.2.4/incl
ude/spp"

2) I've run configure
./configure --host=sh4-linux --target=sh4-linux --without-automount
--without-sendfile-support --with-included-popt --with-included-iniparser
--disable-cups --without-sys-quotas --without-ads --enable-static=yes
--enable-shared=no --prefix=/root/SAMBA/tmp

3) configure stop with error:
checking that the C compiler understands -errwarn... cross
checking that the C compiler understands -qhalt... cross
checking that the C compiler understands negative enum values... configure:
error: in `/root/SAMBA/samba-3.5.6/source3':
configure: error: cannot run test program while cross compiling
See `config.log' for more details.

4) config.log show this:
configure:13070: checking that the C compiler understands negative enum values
configure:13077: error: in `/root/SAMBA/samba-3.5.6/source3':
configure:13080: error: cannot run test program while cross compiling

I've read that I need to setup the "config.site" file. I've
read documentation but I've not understand how to set it.

I answer myself. I hope this can be useful.


1) create with a text editor the file config.site and write into it:
------------------config.site-----------
samba_cv_CC_NEGATIVE_ENUM_VALUES=yes
----------------------------------------
(I've tested the C code and sh4-linux-gcc supports negative enum)

2) set some env vars:
export CONFIG_SITE=/path/to/your/config.site

PREFIX="sh4-linux"
export CC="${PREFIX}-gcc"
export CXX="${PREFIX}-g++"
export LD="${PREFIX}-ld"
export NM="${PREFIX}-nm -B"
export AR="${PREFIX}-ar"
export RANLIB="${PREFIX}-ranlib"
export LN_S="ln -s"
export CFLAGS="-O2"

export PKG_CONFIG_PATH=/opt/STM/STLinux-2.3/devkit/sh4/target/usr/lib/pkgconfig

export LD_LIBRARY_PATH=/opt/STM/STLinux-2.3/devkit/sh4/lib
export LDFLAGS="-L/opt/STM/STLinux-2.3/devkit/sh4/lib
-L/opt/STM/STLinux-2.3/devkit/sh4/lib/gcc/sh4-linux/4.2.4"
export CPPFLAGS="-I/opt/STM/STLinux-2.3/devkit/sh4/include
-I/opt/STM/STLinux-2.3/devkit/sh4/lib/gcc/sh4-linux/4.2.4/include
-I/opt/STM/STLinux-2.3/devkit/sh4/lib/gcc/sh4-lin
ux/4.2.4/include/spp"

export LIBS="-L/opt/STM/STLinux-2.3/devkit/sh4/target/lib
-L/opt/STM/STLinux-2.3/devkit/sh4/target/usr/lib"

3) run configure:
./configure --host=sh4-linux --target=sh4-linux \
        --disable-fam --disable-avahi --disable-swat --disable-cups
--disable-iprint --disable-pie \
        --enable-static=no --enable-shared=yes \
        --without-ldap --without-ads --with-cifsumount --without-pam \
        --without-automount --without-sendfile-support --with-included-popt \
        --without-sys-quotas --without-utmp --without-cluster-support
--without-acl-support \
        --without-winbind --with-included-popt --with-included-iniparser \
        --prefix=/usr/local/samba

4) (remember to install gettext package in your i686 distro)
make
make install

5) strip binaries:
sh4-linux-strip /usr/local/samba/bin/*
sh4-linux-strip /usr/local/samba/sbin/*

That's all

Now you can copy /usr/local/samba/* in your SH4 device.
Many binaries are not useful: I suggest you to remove them.
Remove also man pages
Remember to set a user with smbpasswd and create /usr/local/samba/lib/smb.conf

This is a simple smb.conf :
----------------smb.conf---------------
[global]
workgroup = WORKGROUP
netbios name = SH4
security = share
deadtime = 60
load printers = no
log level = 0
max smbd processes = 6

[movie]
path = /media/hdd/movie
read only = no
guest ok = yes
browseable = yes

[root_dir]
path = /
browseable = yes
read only = no
guest ok = no
