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.

[root @Lil zhanlgei] #gem install mysql2构建原生扩展。这可能需要一段时间...错误：安装mysql2时出错：错误：无法构建gem原生扩展。 / usr / bin / ruby extconf.rb检查rb_thread_blocking_region（）...没有检查rb_wait_for_single_fd（）...没有检查mysql.h ...是检查errmsg.h ...是检查mysqld_error.h ...是创建Makefile

您是否安装了mysql开发包？放置整个构建日志（包括所有内容到下一个shell提示符）

我已经通过yum安装了'mysql-devel'。安装mysql2时的总信息是：[root @Lil zhanlgei] #gem install mysql2构建本机扩展。这可能需要一段时间...错误：安装mysql2时出错：错误：无法构建gem原生扩展。 / usr / bin / ruby extconf.rb检查rb_thread_blocking_region（）...没有检查rb_wait_for_single_fd（）...没有检查mysql.h ...是检查errmsg.h ...是检查mysqld_error.h ...是创建Makefile ..... gcc -shared -o mysql2.so mysql2_ext.o client.o result.o -L。 -L / usr / lib64 -L。 -Wl，-z，relro -rdynamic -Wl，-export-dynamic -Wl，-rpath，/ usr / lib64 / mysql -lruby -L / usr / lib64 / mysql -lmysqlclient -lpthread -lz -lm -lrt -lssl -lcrypto -ldl -lpthread -lrt -ldl -lcrypt -lm -lc / usr / bin / ld：跳过不兼容的/usr/lib/gcc/x86_64-redhat-linux/4.6.3/../../ .. /libz.so搜索-lz / usr / bin / ld时：在搜索-lz / usr / bin / ld时跳过不兼容的/usr/lib/libz.so：找不到-lz

将zlib升级到最新版本。
