This may seem a bit ridiculous, but both MariaDB (fork of mySQL) and the Phidget interface drivers compile with little pain on Raspbian. I say rediculous because MariaDB eats half of the RAM (in 240/16 mode).

To compile MariaDB I did this (commands executed as root) :

Code: Select all

wget "http://downloads.mariadb.org/f/mariadb-5.5.25/kvm-tarbake-jaunty-x86/mariadb-5.5.25.tar.gz/from/http:/download.nus.edu.sg/mirror/mariadb"
tar -xvf mariadb
mv mariadb-5.5.25 maria
cd maria/BUILD
./autorun.sh
cd ..
aptitude install cmake libncurses5-dev bison
./configure
make
make install

adduser mysql
chown -R mysql /usr/local/mysql
cd /usr/local/mysql
scripts/mysql_install_db --user=mysql
cp support-files/mysql.server /etc/init.d/mysqld
/etc/init.d/mysqld start

./bin/mysql_secure_installation

Phidgets :

Code: Select all

wget "http://www.phidgets.com/downloads/libraries/libphidget_2.1.8.20120716.tar.gz"
tar -xvf libphidget_2.1.8.20120716.tar.gz
mv libphidget-2.1.8.20120716 libphi
cd libphi
apt-get install libusb-dev
./configure
make
make install

I am by no means an expert when it comes to Linux, so please correct me if you see something I could do better. Also, I had no idea how to set the compile options for Raspbian.

P.S. These are just cleaned up commands from my .bash_history.

Really helpful - thanks

Thanks for sharing!

Compiling MariaDB takes a long time. It's been bussy for 3.5 hours already, now at 87%. That's normal?

There isn't anybody who has a deb package for this? For Raspbian?

I just installed mysql... and so far it's working quite well for my project (Power meter reading).

I got some issues trying to run it from source. Compiling and make install works fine (I guess), but the rest of the commands doens't run quite well.

Code: Select all

root@raspberrypi:/usr/local/mysql# scripts/mysql_install_db --user=mysql

FATAL ERROR: Could not find mysqld

The following directories were searched:

    /usr/libexec
    /usr/sbin
    /usr/bin

I can run this if I add the basedir option like so:

Code: Select all

root@raspberrypi:/usr/local/mysql# scripts/mysql_install_db --user=mysql --basedir="/usr/local/mysql"

After that I try to run mysqld:

Code: Select all

root@raspberrypi:/usr/local/mysql# /etc/init.d/mysqld start
Starting MySQL
[FAIL] Couldn't find MySQL server (/usr/bin/mysqld_safe) ... failed!

Creating a symlink at that location doesn't really work. What does (half) is the following:

Code: Select all

root@raspberrypi:/usr/local/mysql# /usr/local/mysql/bin/mysqld_safe --user=mysql

From https://kb.askmonty.org/en/generic-build-instructions/

But this generates the following:

Code: Select all

root@raspberrypi:/usr/local/mysql# /usr/local/mysql/bin/mysqld_safe --user=mysql
121207 08:53:33 mysqld_safe Logging to '/var/lib/mysql/raspberrypi.err'.
121207 08:53:33 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
121207 08:53:33 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

Still no running mysql server.

Error file '/var/lib/mysql/raspberrypi.err' says:

Code: Select all

Can't find messagefile '/usr/share/mysql/errmsg.sys'

I got it all working now.

The first error (FATAL ERROR: Could not find mysqld) can be fixed to change the basedir in the config file:

Code: Select all

#basedir        = /usr
basedir         = /usr/local/mysql

This will also solve the second error.

The last error is the missing error message file. Dunno how to fix this a proper way so just copied the needed file from the compile directory. I created a dir on the location (/usr/share/mysql), it wasn't there, and put my language err file in there. You can find proper err file in your compile dir:

Code: Select all

My dir:
root@raspberrypi:/opt/mariadb#
root@raspberrypi:/opt/mariadb# cd sql/share/
charsets/            dutch/               hungarian/           norwegian-ny/        spanish/
CMakeFiles/          english/             italian/             polish/              swedish/
cmake_install.cmake  errmsg-utf8.txt      japanese/            portuguese/          ukrainian/
CMakeLists.txt       estonian/            japanese-sjis/       romanian/
CTestTestfile.cmake  french/              korean/              russian/
czech/               german/              Makefile             serbian/
danish/              greek/               norwegian/           slovak/
root@raspberrypi:/opt/mariadb# cp sql/share/english/errmsg.sys /usr/share/mysql/errmsg.sys

Now the mariadb will just run!

This will save you a bunch of headache if you add it as the last command when installing MariaDB

Code: Select all

sudo cp /usr/local/mysql/support-files/my-medium.cnf /etc/mysql/my.cnf

Most likely will fix any issues your having.

Hello everyone
I've been trying to compile mariadb 10.0.2 on my raspi debian wheezy :3
quite a mess, but finally worked out

Follow the steps by aquarat make the process go fine (thank you by the way...)
I've also got the issue of the messagefile (errmsg.sys) and still is, but I thought that it was the point of my problems with the server and but was not. When I start the service, it raises well, but when I tried to access thru the client, it never let me in.
I've resolved this by setting in the my.cnf where exactly was my database files by:
datadir=/var/lib/mysql
on [mysqld] of my.cnf
also there put the famous
basedir=/usr/local/mysql
I suposse that while mysqld was not finding the logins tables it would not allow me to login.
Remember that by default mariadb sock file changes to /tmp/mysql.sock, so change this directory in your php.ini file if you think to use it...
PS: excuse me about my english... and greetings form Spain!!!!
