続々Railsでデモを作れぇ! (T-T)
さてと、とりあえずCentOS4.4でRails2.0での動作は確認できたけど、
元々のcastleの環境をどうにかしたい。
/usr/local/lib/ruby/gems/1.8/gems/mysql-2.7配下でmysql.soをビルドし直すと、
ruby extconf.rb --with-mysql-include=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql checking for main() in -lmysqlclient... no checking for mysql_ssl_set()... no checking for mysql.h... yes creating Makefile [root@castor mysql-2.7]# make gcc -I. -I. -I/usr/local/lib/ruby/1.8/x86_64-linux -I. -DHAVE_MYSQL_H -I/usr/include/mysql -I/usr/local/include -fPIC -g -O2 -c mysql.c gcc -shared -L'/usr/lib/mysql' -Wl,-R'/usr/lib/mysql' -L'/usr/local/lib' -Wl,-R'/usr/local/lib' -L'/usr/local/lib' -Wl,-R'/usr/local/lib' -o mysql.so mysql.o -ldl -lcrypt -lm -lc [root@castor mysql-2.7]# ruby ./test.rb localhost root castle accident_test ruby: symbol lookup error: ./mysql.so: undefined symbol: mysql_get_client_version
mysql.hにはちゃんとmysql_get_client_versionの定義はある（コンパイル出来ているんだから当然）
rpm -qi mysqlとすると、

ちょこっとバージョンが上がった？
で、

で、何だかFailureになっているがmysqlにはアクセスできているようなので、とりあえずOK?

うん、何とかテーブルは出来たみたい。

ということで、結局は、mysqlのlibパスが/usr/lib/mysqlではなくて、/usr/lib64/mysqlが正解だったんじゃないか？（パッケージを入れ替えたのが良かったのかもしれないけど）
