編譯 MySQL 的 “Linux thread not found” 問題
Posted on October 31st, 2007 No comments今日安裝一台新 Server，系統是 RHEL 5，在編譯 MySQL 4.0.x 的時候出現問題：
# ./configure –prefix=/usr/local/mysql
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.看來 MySQL 4.0 不支援新核心使用了 NTPL 這種新的線程，最後用了這個方法解決：
# cp /usr/include/pthread.h /usr/include/pthread.h.bak
# echo ‘/* Linuxthreads */’ >> /usr/include/pthread.h然後重新編譯及加入 –with-pthread 及 –with-named-thread-lib 兩個參數：
# ./configure –with-pthread –with-named-thread-lib=-lpthread
# make && make install這樣就可以正常編譯及安裝 MySQL 4.0 了。
