Erlang 开机失败产生故障转储，如何调试?

Question

我已经将Erlang移植到基于X86的操作系统上。尝试启动它会产生一些输出和故障转储。我需要帮助确定失败的原因。

我在启动时包含了 -init_debug，并查看了 Windows 上运行的 erlang 实例上的故障转储。在崩溃转储中，pid <0.2.0>不存在，我认为它应该存在。我欢迎提前提出任何建议。

Answer 1

尝试安装erlang-tools。例如，对于 Ubuntu：

$ sudo apt-get install erlang-tools

或者，您可以从操作系统中删除 Erlang 并通过 https://www.erlang-solutions.com/resources/download.html 重新安装

Answer 2

我取得了进步。 我用"-g"重建以添加符号，以便我可以调试，清理所有.o，重建...它开始工作。我猜我配置错误了。
