[ Need bluetooth] DIY Preamplifier with buildin Raspberry pi B streamer

[lykkedk]

Hi all.

I have been very busy, last few months creating my new Preamp., with raspberry pi buildin.

I allway's end up with some diy hifi equipment, with lots of features and boxes, with power switches  ... So i wanted something simple this time, which is easy for also my kids and wife to use.

This preamp, has no but a powerswitch at back, turning everything on with just one click. -When preamp. turns on, it automatic turns on my poweramp. -So piCore is the only usefull system, for such a system i guess 

So, while enjoying radio/music/streams, i thought it would be fun to have a bluetooth attached also, so i found one and plugged in the last spare usb-port of the PI.

I posted some quistions at another topic http://forum.tinycorelinux.net/index.php/topic,17945.0.html.
But i think it would be better to open up a new thread on this.

This i installed from tce :

tce - Tiny Core Extension browser

    1. bluetooth-3.12.36-piCore+.tcz
    2. bluez-hcidump-doc.tcz
    3. bluez-hcidump.tcz

But i need other tools, like bluez, bluez-utils, bluez-tools, blues-alsa etc...

Well i will wait and see, if someone chimes in here.

You can find the corepure64 instructions to compile bluez here:

http://www.tinycorelinux.net/6.x/x86_64/tcz/src/bluez/compile_bluez

..it should be relatively easy to modify these for your purposes.

Note that it is awkward to use bluetooth with alsa alone, but much easier to use it with pulseaudio at the cost of a lot of bloat.

Thank.. Will look into this.

  Apperantly i connot make it!

I think i need the GLIB2 >= 2.28... Maybe Bela' have an idea of why it does not compile.

You need to install pkg-config, and maybe other packages.

[lykkedk]

So.

I created pkg-config from this source http://pkgconfig.freedesktop.org/releases/

It compiled without problems, and therefore i created a .tcz for the sake of it. (Only pkg-config.list here, due to attachment size 

I loaded it, and tried to run ./configure on my bluez 5.30 once more, but no change. -Compiler stops at same error.

Rgds; Jesper.

[lykkedk]

So.

I now loaded my newly build pkg-config.tzc, and did export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig.

Now ./configure finds the GLIB 

It now stops at another error? -As i think udev is complicated, it might be hard to go pass this error.

What i have loaded is this :

libudev-dev
squashfs-tools
dbus-glib-dev
readline-dev
glib2-locale
glib2-python
glib2-dev
mc
nano
zip
bluetooth-3.12.36-piCore+
bluez-hcidump
usbutils
compile-essentials
linux-3.12.y_api_headers
/home/tc/pkg-config

Commandline snippet :

checking for GLIB... yes
checking for DBUS... yes
checking D-Bus configuration directory... /usr/local/etc
checking D-Bus system bus services dir... /usr/local/share/dbus-1/system-services
checking D-Bus session bus services dir... /usr/local/share/dbus-1/services
checking for UDEV... yes
checking for udev_hwdb_new in -ludev... no
checking udev directory... configure: error: udev directory is required

Rgds; Jesper.

If you compile pkg-config with:

Code: [Select]

--with-pc-path="/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/share/pkgconfig"..you won't need to set $PKG_CONFIG_PATH everytime.

Are /etc/udev/rules.d and /lib/udev present?

[curaga]

There's a pre-existing pkg-config extension, as well.

[lykkedk]

Juanito .

Are /etc/udev/rules.d and /lib/udev present?

Yes

Then I guess you'll need to look in config.log to see why you get this:

Code: [Select]

checking udev directory... configure: error: udev directory is required

[lykkedk]

Hi.

Not much :

configure:13415: checking udev directory
configure:13419: error: udev directory is required

Rgds; Jesper.

[Juanito]

How about line 13419 of the configure script?

[lykkedk]

Hi back...

First of, the link you gave me earlier, with instructions for compiling on core64, the line with
tce-load -i dbus-glib-dev libical-dev readline-dev udev-lib-dev

I better tell, that both libical-dev and udev-lib-dev is nonexistant on piCore (will try to build later maybee)

If i --disable -with udev, in configure, the scripts end at missing libical.

Anyway, you asked about line 13419 

Line 13419 is where the * is 

# Check whether --with-udevdir was given.
if test "${with_udevdir+set}" = set; then :
  withval=$with_udevdir; path_udevdir=${withval}
fi

if (test "${enable_udev}" != "no" && test -z "${path_udevdir}"); then
        { $as_echo "$as_me:${as_lineno-$LINENO}: checking udev directory" >&5
$as_echo_n "checking udev directory... " >&6; }
        path_udevdir="`$PKG_CONFIG --variable=udevdir udev`"
        if (test -z "${path_udevdir}"); then
        *       as_fn_error $? "udev directory is required" "$LINENO" 5
        fi
        { $as_echo "$as_me:${as_lineno-$LINENO}: result: ${path_udevdir}" >&5
$as_echo "${path_udevdir}" >&6; }
fi
UDEV_DIR=${path_udevdir}

[Juanito]

I guess it's called libudev-dev rather than udev-lib-dev in the raspberry repo and I'd also guess there's a ./configure switch to disable libical (check "./configure --help").

Do you have libudev-dev loaded?
