在装有mysql5的ubuntu上再安装mysql4


解压mysql4.0.26
root@www:/db# tar zxvf mysql-4.0.26.tar.gz
备份mysql5的数据目录
root@www:/db# tar czvf mysql5.data.tar.gz mysql5
编译
root@www:/db# cd mysql-4.0.26
root@www:/db/mysql-4.0.26# ./configure --prefix=/db/mysql4
最后提示:
checking "LinuxThreads"... "Not found"
configure: error: This is a linux system and Linuxthreads was not
found. On linux Linuxthreads should be used. Please install Linuxthreads
(or a new glibc) and try again. See the Installation chapter in the
Reference Manual for more information.
怎么会没有Linuxthreads?查看
root@www:/db/mysql-4.0.26# gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --
with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --program-suffix=-4.1
--enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --enable-checking=release i486-linux-gnu
Thread model: posix
gcc version 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
也许是gcc版本太新的原因?上网一查,是因为新内核使用了NTPL这种先进的线程处理方式,于是就这样:
root@www:/db/mysql-4.0.26# cp /usr/include/pthread.h /usr/include/pthread.h.bak
root@www:/db/mysql-4.0.26# echo '/* Linuxthreads */' >> /usr/include/pthread.h
然后编译,并且加了点参数
root@www:/db/mysql-4.0.26# ./configure --prefix=/db/mysql4 --with-unix-socket-path=/db/mysql4/mysql.sock --with-tcp-port=3304
--with-low-memory
在检测Linuxthreads地方显示为Found,但后来还是停下了,
checking whether signal handlers are of type void... yes
checking for tgetent in -lncurses... no
checking for tgetent in -lcurses... no
checking for tgetent in -ltermcap... no
checking for termcap functions library... configure: error: No curses/termcap li
brary found
看来要装ncurses,
root@www:/db/mysql-4.0.26# apt-get install ncurses
正在读取软件包列表... 完成
正在分析软件包的依赖关系树
Reading state information... 完成
现在没有可用的软件包 ncurses，但是它被其它的软件包引用了。
这可能意味着这个缺失的软件包可能已被废弃，
或者只能在其他发布源中找到
