For information about installing MySQL on Solaris using PKG distributions, see Chapter 4, Installing MySQL on Solaris.
On Solaris, you may run into trouble even before you get the MySQL distribution unpacked, as the Solaris tar cannot handle long file names. This means that you may see errors when you try to unpack MySQL.
If this occurs, you must use GNU tar (gtar) to unpack the distribution.
If you get the following error from configure, it means that you have something wrong with your compiler installation:
checking for restartable system calls... configure: error can not run test programs while cross compiling
In this case, you should upgrade your compiler to a newer
version. You may also be able to solve this problem by inserting
the following row into the
If you are using Solaris on a SPARC, the recommended compiler is gcc 2.95.2 or 3.2. You can find this at http://gcc.gnu.org/. Note that gcc 2.8.1 does not work reliably on SPARC.
The recommended configure line when using gcc 2.95.2 is:
CC=gcc CFLAGS="-O3" \ CXX=gcc CXXFLAGS="-O3 -felide-constructors -fno-exceptions -fno-rtti" \ ./configure --prefix=/usr/local/mysql --with-low-memory \ --enable-assembler
If you have an UltraSPARC system, you can get 4% better
performance by adding
-Wa,-xarch=v8plusa to the
CXXFLAGS environment variables.
If you have Sun's Forte 5.0 (or newer) compiler, you can run configure like this:
CC=cc CFLAGS="-Xa -fast -native -xstrconst -mt" \ CXX=CC CXXFLAGS="-noex -mt" \ ./configure --prefix=/usr/local/mysql --enable-assembler
To create a 64-bit binary with Sun's Forte compiler, use the following configuration options:
CC=cc CFLAGS="-Xa -fast -native -xstrconst -mt -xarch=v9" \ CXX=CC CXXFLAGS="-noex -mt -xarch=v9" ASFLAGS="-xarch=v9" \ ./configure --prefix=/usr/local/mysql --enable-assembler
To create a 64-bit Solaris binary using gcc,
CXXFLAGS and remove
--enable-assembler from the
In the MySQL benchmarks, we obtained a 4% speed increase on
UltraSPARC when using Forte 5.0 in 32-bit mode, as compared to
using gcc 3.2 with the
If you create a 64-bit mysqld binary, it is 4% slower than the 32-bit binary, but can handle more threads and memory.
When using Solaris 10 for x86_64, you should mount any file
systems on which you intend to store
files with the
forcedirectio option. (By
default mounting is done without this option.) Failing to do so
will cause a significant drop in performance when using the
InnoDB storage engine on this platform.
If you get a problem with
sched_yield, you can fix this by adding
LIBS=-lrt to the configure
For compilers older than WorkShop 5.3, you might have to edit the configure script. Change this line:
#if !defined(__STDC__) || __STDC__ != 1
If you turn on
__STDC__ with the
-Xc option, the Sun compiler can't compile with
pthread.h header file. This is
a Sun bug (broken compiler or broken include file).
If mysqld issues the following error message
when you run it, you have tried to compile MySQL with the Sun
compiler without enabling the
libc internal error: _rmutex_unlock: rmutex not held
CXXFLAGS and recompile.
If you are using the SFW version of gcc
(which comes with Solaris 8), you must add
/opt/sfw/lib to the environment variable
LD_LIBRARY_PATH before running
If you are using the gcc available from
sunfreeware.com, you may have many problems.
To avoid this, you should recompile gcc and
binutils on the machine where you are
If you get the following error when compiling MySQL with gcc, it means that your gcc is not configured for your version of Solaris:
gcc -O3 -g -O2 -DDBUG_OFF -o thr_alarm ..../thr_alarm.c: In function `signal_hand': ./thr_alarm.c:556: too many arguments to function `sigwait'
The proper thing to do in this case is to get the newest version of gcc and compile it with your current gcc compiler. At least for Solaris 2.5, almost all binary versions of gcc have old, unusable include files that break all programs that use threads, and possibly other programs as well.
Solaris does not provide static versions of all system libraries
so you cannot compile MySQL with
you try to do so, you get one of the following errors:
ld: fatal: library -ldl: not found undefined reference to `dlopen' cannot find -lrt
If you link your own MySQL client programs, you may see the following error at runtime:
ld.so.1: fatal: libmysqlclient.so.#: open failed: No such file or directory
This problem can be avoided by one of the following methods:
If you have problems with configure trying to
-lz when you do not have
zlib installed, you have two options:
If you want to be able to use the compressed communication
protocol, you need to get and install
Run configure with the
--with-named-z-libs=no option when building
If you are using gcc and have problems with
loading user-defined functions (UDFs) into MySQL, try adding
-lgcc to the link line for the UDF.
If you would like MySQL to start automatically, you can copy
/etc/init.d and create a symbolic link to
If too many processes try to connect very rapidly to mysqld, you should see this error in the MySQL log:
Error in accept: Protocol error
You might try starting the server with the
--back_log=50 option as a
workaround for this. (Use
-O back_log=50 before
To configure the generation of core files on Solaris you should
use the coreadm command. Because of the
security implications of generating a core on a
setuid() application, by default, Solaris
does not support core files on
programs. However, you can modify this behavior using
coreadm. If you enable
setuid() core files for the current user,
they will be generated using the mode 600 and owned by the
