在上述情况下，我收到以下编译错误。有人能告诉我为什么吗？我使用以下文档作为我的指导方针

对“rpl_malloc”进行简单的 Google 搜索会发现许多关于此问题的参考资料，并提供解决方案建议。问题是 Autoconf 配置脚本malloc由于某种原因无法找到，并试图回退到rpl_malloc. 有几个建议可以解决这个问题：

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

ac_cv_func_malloc_0_nonnull=yes ./configure <your configure options>

或者

2.) 手动更改配置脚本以通过在该行前面加上 . 来注释掉该rpl_malloc problem AC_FUNC_MALLOC行#。

（参考：这篇博文等）
