Answer 1

simple Google search on "rpl_malloc"找到许多对此问题的引用，并提供了解决方案的建议。问题是Autoconf配置脚本由于某种原因无法找到malloc，并试图回退到rpl_malloc。有几个建议可以解决这个问题：

1。）在运行ac_cv_func_malloc_0_nonnull=yes之前定义configure环境变量，例如通过运行configure（假设bash shell）：

ac_cv_func_malloc_0_nonnull=yes ./configure <your configure options>

或

2.。）手动更改配置脚本，以rpl_malloc problem AC_FUNC_MALLOC行为其添加注释，并在其前面添加#。
