If you are using egcs 1.1.2 on Digital Unix, you should upgrade to gcc 2.95.2, because egcs on DEC has some serious bugs!
When compiling threaded programs under Digital Unix, the
documentation recommends using the
option for cc and cxx
-lmach -lexc libraries (in addition
-lpthread). You should run
configure something like this:
CC="cc -pthread" CXX="cxx -pthread -O" \ ./configure --with-named-thread-libs="-lpthread -lmach -lexc -lc"
When compiling mysqld, you may see a couple of warnings like this:
mysqld.cc: In function void handle_connections()': mysqld.cc:626: passing long unsigned int *' as argument 3 of accept(int,sockadddr *, int *)'
You can safely ignore these warnings. They occur because configure can detect only errors, not warnings.
If you start the server directly from the command line, you
may have problems with it dying when you log out. (When you
log out, your outstanding processes receive a
SIGHUP signal.) If so, try starting the
server like this:
nohup mysqld [
nohup causes the command following it to
SIGHUP signal sent from the
terminal. Alternatively, start the server by running
mysqld_safe, which invokes
mysqld using nohup for
you. See mysqld_safe — MySQL Server Startup Script.
If you get a problem when compiling
mysys/get_opt.c, just remove the
#define _NO_PROTO line from the start of
If you are using Compaq's CC compiler, the following configure line should work:
CC="cc -pthread" CFLAGS="-O4 -ansi_alias -ansi_args -fast -inline speed \ -speculate all -arch host" CXX="cxx -pthread" CXXFLAGS="-O4 -ansi_alias -ansi_args -fast -inline speed \ -speculate all -arch host -noexceptions -nortti" export CC CFLAGS CXX CXXFLAGS ./configure \ --prefix=/usr/local/mysql \ --with-low-memory \ --enable-large-files \ --enable-shared=yes \ --with-named-thread-libs="-lpthread -lmach -lexc -lc" gnumake
If you get a problem with libtool when compiling with shared libraries as just shown, when linking mysql, you should be able to get around this by issuing these commands:
cd mysql /bin/sh ../libtool --mode=link cxx -pthread -O3 -DDBUG_OFF \ -O4 -ansi_alias -ansi_args -fast -inline speed \ -speculate all \ -arch host -DUNDEF_HAVE_GETHOSTBYNAME_R \ -o mysql mysql.o readline.o sql_string.o completion_hash.o \ ../readline/libreadline.a -lcurses \ ../libmysql/.libs/libmysqlclient.so -lm cd .. gnumake gnumake install scripts/mysql_install_db
