    132 MySQL Technical Reference for Version 4.0.3 lib/cmds/aixcmds5/uname.htm.  This will give you a machine type and a machine model you can use to determine what type of CPU you have. If you have problems with signals (MySQL dies unexpectedly under high load) you may have found an OS bug with threads and signals.  In this case you can tell MySQL not to use signals by con guring with: shell> CFLAGS=-DDONT_USE_THR_ALARM CXX=gcc \ CXXFLAGS="-felide-constructors -fno-exceptions -fno-rtti \ -DDONT_USE_THR_ALARM" \ ./configure --prefix=/usr/local/mysql --with-debug --with-low- This doesn't a ect the performance of MySQL, but has the side e ect that you can't kill clients that are \sleeping" on a connection with mysqladmin kill or mysqladmin shutdown. Instead, the client will die when it issues its next command. On some versions of AIX, linking with libbind.a makes getservbyname core dump.  This is an AIX bug and should be reported to IBM. For AIX 4.2.1 and gcc you have to do the following changes. After  con guring,  edit  `config.h'  and  `include/my_config.h'  and  change  the  line  that says #define HAVE_SNPRINTF 1 to #undef HAVE_SNPRINTF And nally, in `mysqld.cc' you need to add a prototype for initgoups. #ifdef _AIX41 extern "C" int initgroups(const char *,int); #endif 2.6.6.5  SunOS 4 Notes On SunOS 4,  MIT-pthreads is needed to compile MySQL, which in turn means you will need GNU make. Some SunOS 4 systems have problems with dynamic libraries and  libtool.  You can use the following configure line to avoid this problem: shell> ./configure --disable-shared --with-mysqld-ldflags=-all-static When compiling readline, you may get warnings about duplicate de nes.  These may be ignored. When compiling mysqld, there will be some implicit declaration of function warnings. These may be ignored. 2.6.6.6  Alpha-DEC-UNIX Notes (Tru64) If you are using egcs 1.1.2 on Digital Unix, you should upgrade to gcc 2.95.2, as egcs on DEC has some serious bugs!
