对 xdr_float、...等的未定义引用

Question

链接到“rpc”库时遇到问题。我的系统是 OpenSUSE Leap 15.5。这是 shell (Bash) 的输出：

我正在从 reproducibility.org 编译 Madagascar 软件。完成配置，安装依赖项，开始编译过程。但是“build/user/gee”中的配置文件似乎有问题。配置文件如下：

其他目录中的其他配置文件也存在该问题。通过在 'env.Prepend' 行中将 'libtirpc' 添加到 'LIBS=[]' 中，到目前为止已经解决了问题。

请以简单的方式询问任何必要的信息！

别嫌我无能，我不是程序员！谢谢！

Answer 1

在Makefile中的gcc命令行中添加tirpc库：

   gcc -o build/..... -ltirpc

您必须找到并更改该文件。
