安装mysql，mysql2 gems在fedora16上失败

Question

这是我的命令信息：

[root@Lil lib]# gem install mysql -- --with-mysql-config=/usr/bin/mysql_config
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.
        /usr/bin/ruby extconf.rb --with-mysql-config=/usr/bin/mysql_config
checking for mysql_ssl_set()... no
checking for rb_str_set_len()... no
checking for rb_thread_start_timer()... no
checking for mysql.h... yes

，当我输入命令“gem install mysql2”时，信息是：

[root@Lil lib]# gem install mysql2
Building native extensions.  This could take a while...
ERROR:  Error installing mysql2:
    ERROR: Failed to build gem native extension.

您安装了mysql开发包吗？将整个构建日志(包括所有内容到下一个shell提示符)

在安装yum.the时，我已经安装了“mysql-devel”，安装mysql2的总信息是:root@Lil zhanlgei#宝石安装mysql2构建本机扩展。这需要一段时间..。错误:安装mysql2时出错:错误:生成gem本机扩展失败。/usr/bin/ruby extconf.rb检查rb_thread_blocking_region().不检查rb_wait_for_single_fd().没有检查没药..。是的，检查一下.是的检查mysqld_error.h..。是的创造了Makefile ..。gcc -shared -o mysql2.so mysql2_ext.o client.o结果.o -L.-L/usr/lib64 64 -L.-Wl，-z，relro -rdynamic -Wl，-导出-dynamic -Wl，-rpath，/usr/lib 64/mysql -lruby -L/usr/lib 64/mysql -lmysqlclient -lpthread -lz -lm -lrt -lssl -lcrypto -ldl -lpthread -ldl -lcrypt -lm -lc /usr/bin/ld:当搜索-lz /usr/bin/ld:跳过不兼容的/usr/lib/libz.so时，搜索-lz /usr/bin/ld: find -lcrypto

将zlib升级到最新版本。
