# 2005-07-16  Solaris 下安装Perl的DBD-mysql模块失败的原因以及解决办法

Solaris下安装Perl的`DBD::Mysql`模块，已经出了两次问题了。现总结如下：

问题一：无法找到mysql\_config 1. 下载DBD-mysql-3.0000 2. 解压 3. make Makefile.PL 4. 提示找不到mysql\_config

解决办法： 出现这个问题是因为没有将`mysql_config`加入环境变量PATH中，只要将`mysql/bin`目录加入到路径中就可以了。

```
PATH=$PATH:/usr/local/mysql/bin
export PATH
```

然后重新 `make Makefile.PL`

问题二：无法找到库 `libmysqlclient.so` Solaris 的mysql发行版本的库文件都是.a的静态库，`DBD::Mysql`模块需要.so的动态库编译。可以下载带源码的Mysql自行编译出.so的动态库。

问题三：编译不通过 那是因为mysql*config给Makefile.PL的cflags参数不正确。在我的Solaris上，给的参数是 \`-I/usr/local/mysql/include -Xa -xstrconst -mt -D\_FORTEC* -xarch=v9`，gcc 版本是 3.4.0，而`-Xa -xstrconst -mt -xarch=v9\`这几个参数，solaris上的gcc不认。

因此我手工指定参数生成 Makefile：`perl Makefile.PL --cflags="-I/usr/local/mysql/include -D_FORTEC_"`，之后`make ; make install` 一切顺利。
