任务是在 Red Hat 衍生产品上安装 rrdtool，并且禁止使用 yum 或软件包。将 rrdtool 的所有依赖项从源代码编译到单独的目录中：/apps/run/sepatare_folder

所以基本上我所拥有的一切看起来像这样：

ls
cairo        glib         pango        pixman
--
pwd
/apps/run

编译四个依赖项后，rrdtool 在 ./configure --prefix=/apps/run/rrdtool 期间抱怨

编译器找不到库 [因为我将它们编译到单独的文件夹中，而不是标准，因为这是被禁止的]

所有警告如下：

我确实有所有缺少的库，但需要告诉编译器如何找到它们是一个很大的痛苦。例如缺少glib-2.0 在这里：

有很好的建议，但不幸的是我无法理解它们：

  • 您可能希望将 PKG_CONFIG_PATH 变量设置为指向其位置。
  • 也许您需要适当地设置 LDFLAGS 和 CPPFLAGS 以便编译器和链接器可以找到 libglib-2.0 及其头文件。

不够熟练地将PKG_CONFIG_PATH设置为包含可以找到多个所需库 [例如 glib-2.0.pc、cairo-ps、cairo-png、..] 的目录。尝试过这样的事情：

export LD_LIBRARY_PATH=/apps/run/glib/lib;export LD_LIBRARY_PATH=/apps/run//apps/run/cairo/lib

但不工作。也不确定这是否足够，因为有关于适当设置LDFLAGS和CPPFLAGS的建议。试过这个：

export LDFLAGS='-L/apps/run/cairo/libs'

但这似乎不正确。或者我应该将 LDFLAGS 和 CPPFLAGS 指定为 ./configure 的一部分？语法应该是什么？请建议，寻找一般的howtos，但不能适应我的环境。谢谢

要设置路径，例如LD_LIBRARY_PATHof PKG_CONFIG_PATH，您应该使用单个export，并使用 分隔路径:。例如：

export PKG_CONFIG_PATH=/my/path:/my/other/path:/yet/another/path

一个接一个地运行多个导出，就像你展示的那样，LD_LIBRARY_PATH将覆盖它们，即只保留最后一个。一般来说，总是包含当前值是明智的（如果它是空的也没关系）：

export PKG_CONFIG_PATH=/my/path:/my/other/path:/yet/another/path:$PKG_CONFIG_PATH

尝试cairo-png.pc在您的系统上查找该文件，然后将其设置PKG_CONFIG_PATH为它所在的目录。

不需要摆弄LD_LIBRARY_PATHof LDFLAGS， pkgconfig.pc文件应该会为您处理好。
