【问题描述】：

我正在尝试在我的 RHEL/CENTOS 7 机器上构建 mapnik 2.2.0 RPM 文件。所以我从 Fedora 22 获取了 RPM SRC 文件，即 mapnik-2.2.0-11.fc21.src.rpm （我的结果与 mapnik-2.2.0-5.fc20.src.rpm 相同）当我运行 rpmbuild 时，我收到以下错误消息：

Welcome to Mapnik...

【解决方案1】：

Mapnik 通常在其源代码树中带有 AGG 库的大量修补版本。然而，Fedora 构建禁用了这一点，而是将 Mapnik-AGG 补丁直接放在它自己的 AGG 包中（因为他们不喜欢在其他地方复制系统库）。

您要么需要一个与修补过的 Fedora 版本功能兼容的 CentOS AGG 库，要么您必须修改 Mapnik 构建以禁用“system_agg”补丁（并从规范文件）。
