HOWTO: Install Mysql 5.1 for SPARC64 under Debian Lenny

If you happen to own a SPARC64 box, you’ll probably already know that even if the kernel is 64bit the userland comes from the normal SPARC Debian port, so it’s 32bit. Mysql is no exception, with all the 32bit limitations – mainly the 4GB RAM per process limit.

This is really  a PITA because if you have a SPARC64 box probably it has got plenty of RAM and you want to use it at its full potential, without having to messing around with Solaris (yeah, I don’t like it very much, I’m sorry).

This guide covers Mysql 5.1 installation in Debian Lenny, so we have to use SID repositories.


# echo "deb http://ftp.de.debian.org/debian/ sid main" >> /etc/apt/sources.list
# echo "deb-src http://ftp.de.debian.org/debian/ sid main" >> /etc/apt/sources.list


then let’s edit our apt preferences to avoid massive update on next dist-upgrade :)

# vim /etc/apt/preferences
Package: *
Pin: release a=stable
Pin-Priority: 900
Package: *
Pin: release a=sid
Pin-Priority: 100


and then update our repo list

# aptitude update


And here we go:

# apt-get build-dep mysql-server-5.1
# mkdir /tmp/mysql-build; cd /tmp/mysql-build
# apt-get source mysql-server-5.1
# vim mysql-dfsg-5.1*/debian/rules


here we touch a little the rules for compiling cause there are a couple of things that are not going to work by default.

The MAKE_J variable doesn’t work very well, so you can modify the grep to look for “CPU” instead of “processor” or you could hardcode it to the number of processor you have. This will make compilation a lot faster.

MAKE_J = -j$(shell if [ -f /proc/cpuinfo ] ; then grep -c CPU* /proc/cpuinfo ; else echo 1 ; fi)


then edit the CFLAGS variable because it’s used to compile some library that will ignore the environment variables we are going to set later in this howto.

CFLAGS=$${MYSQL_BUILD_CFLAGS:-"-O3 -DBIG_JOINS=1 -m64 -mcpu=niagara2 ${FORCE_FPIC_CFLAGS}"} \

it should be about line 73. Please note that -m64 will make it 64bit so it’s mandatory while the mcpu flag it’s to optimize the executable for your CPU. In my case it’s a niagara2 chip but you can use another CPU as well. Check the GCC documentation for more details
Save and quit and then we can start with the compilation process:

# export CFLAGS="-m64 -mcpu=niagara2 -O2 -g"
# export CXXFLAGS="-m64 -mcpu=niagara2 -O2 -g"
# export CPPFLAGS="-m64 -mcpu=niagara2 -O2 -g"
# export LDFLAGS="-m64 -mcpu=niagara2 -O2 -g"
# export DEB_BUILD_OPTIONS="nocheck"
# debuild -us -uc --preserve-env


that’s it. After some minutes (depending on your HW), you should have in /tmp/mysql-build all your new DEBs which you can install with dpkg -i. I advice to install the stock mysql-server-5.1 with aptitude before to get all dependencies installed, then you can use dpkg with your new DEBs.
