カーネルの設定
If you are building this package to use bluetooth devices (rather
than as a build dependency), enable the following options in the
kernel configuration, also the options in the 「Cryptographic API」
section if you intend to run the tests, and recompile the kernel if
necessary:
General setup --->
# If it is disabled, [TIMERFD] and [EVENTFD] will be hidden and
# enabled implicitly. We DO NOT recommend to enable [EXPERT]
# unless you are really an expert user:
[ /*] Configure standard kernel features (expert users) ---> [EXPERT]
[*] Enable timerfd() system call [TIMERFD]
[*] Enable eventfd() system call [EVENTFD]
[*] Networking support ---> [NET]
<*/M> Bluetooth subsystem support ---> [BT]
[*] Bluetooth Classic (BR/EDR) features [BT_BREDR]
<*/M> RFCOMM protocol support [BT_RFCOMM]
[*] RFCOMM TTY support [BT_RFCOMM_TTY]
<*/M> BNEP protocol support [BT_BNEP]
[*] Multicast filter support [BT_BNEP_MC_FILTER]
[*] Protocol filter support [BT_BNEP_PROTO_FILTER]
<*/M> HIDP protocol support [BT_HIDP]
Bluetooth device drivers --->
# Select the appropriate drivers for your bluetooth hardware.
# There are more vendor-specific drivers not listed here:
< /*/M> HCI USB driver [BT_HCIBTUSB]
< /*/M> HCI SDIO driver [BT_HCIBTSDIO]
< /*/M> HCI UART driver [BT_HCIUART]
<*/M> RF switch subsystem support ---> [RFKILL]
-*- Cryptographic API ---> [CRYPTO]
Crypto core or helper --->
<*/M> Userspace cryptographic algorithm configuration [CRYPTO_USER]
Block ciphers --->
<*/M> AES (Advanced Encryption Standard) [CRYPTO_AES]
AEAD (authenticated encryption with associated data) ciphers --->
<*/M> CCM (Counter with Cipher Block Chaining-MAC) [CRYPTO_CCM]
Hashes, digests, and MACs --->
<*/M> CMAC (Cipher-based MAC) [CRYPTO_CMAC]
Userspace interface --->
<*/M> Hash algorithms [CRYPTO_USER_API_HASH]
<*/M> Symmetric key cipher algorithms [CRYPTO_USER_API_SKCIPHER]
<*/M> AEAD cipher algorithms [CRYPTO_USER_API_AEAD]
BlueZ のインストール
Now, make some changes needed for SystemV systems:
patch -Np1 -i ../bluez-5.71-obexd_without_systemd-1.patch
以下のコマンドを実行して BlueZ をビルドします。
./configure --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--enable-library \
--disable-manpages \
--disable-systemd &&
make
ビルド結果をテストする場合は make
check を実行します。
root ユーザーになって以下を実行します。
make install &&
ln -svf ../libexec/bluetooth/bluetoothd /usr/sbin
root ユーザーになって、主要な設定ファイルをインストールします。
install -v -dm755 /etc/bluetooth &&
install -v -m644 src/main.conf /etc/bluetooth/main.conf
API ドキュメントが必要な場合は root
ユーザーになって以下を実行します。
install -v -dm755 /usr/share/doc/bluez-5.71 &&
install -v -m644 doc/*.txt /usr/share/doc/bluez-5.71
コマンド説明
--disable-manpages: This
switch disables generating the manual pages because of the reliance
on 'rst2man' in docutils. Remove this switch if you have docutils-0.20.1 installed and wish to
generate the manual pages.
--enable-library: This
switch enables building the BlueZ
4 compatibility library which is required by some applications.
--disable-systemd: This
switch is needed because systemd
is not part of LFS/BLFS. If you are using systemd, remove this
switch.
ln -svf
../libexec/bluetooth/bluetoothd /usr/sbin: This
command makes access to the bluetooth daemon more convenient.
BlueZ の設定
設定ファイル
/etc/bluetooth/main.conf is
installed automatically during the install. Additionally, there
are three supplementary configuration files.
/etc/sysconfig/bluetooth is installed as a part of the boot
script below. In addition, you optionally can install the
following, as the root user:
cat > /etc/bluetooth/rfcomm.conf << "EOF"
# Start rfcomm.conf
# Set up the RFCOMM configuration of the Bluetooth subsystem in the Linux kernel.
# Use one line per command
# See the rfcomm man page for options
# End of rfcomm.conf
EOF
cat > /etc/bluetooth/uart.conf << "EOF"
# Start uart.conf
# Attach serial devices via UART HCI to BlueZ stack
# Use one line per device
# See the hciattach man page for options
# End of uart.conf
EOF
ブートスクリプト
To automatically start the bluetoothd daemon when the
system is rebooted, install the /etc/rc.d/init.d/bluetooth bootscript from the
blfs-bootscripts-20231119 package.
make install-bluetooth
