我正在x86上的Ubuntu Linux上的第三方C库上开发Erlang Package 器，所以我正在创建一个NIF。有时我的代码（我认为）崩溃，导致一个核心文件。不幸的是，stacktrace并没有真正的帮助：

(gdb) bt
#0  0x00007fc22229968a in ?? ()
#1  0x0000000060e816d8 in ?? ()
#2  0x0000000007cd48b0 in ?? ()
#3  0x00007fc228031410 in ?? ()
#4  0x00007fc228040b80 in ?? ()
#5  0x00007fc228040c50 in ?? ()
#6  0x00007fc22223de0b in ?? ()
#7  0x0000000000000000 in ?? ()

即使我使用调试信息构建了NIF.so文件：

ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=b70dd1f2450f5c0e9980c8396aaad2e1cd29024c, with debug_info, not stripped

beam还包含调试信息：

ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=e0a5dba6507b8c2b333faebc89fbc6ea2f7263b9, for GNU/Linux 3.2.0, with debug_info, not stripped

但是，info sharedlibrary既不显示NIF，也不显示第三方库：

我发现this回答提到 “Erlang VM不加载公开了全局符号的NIF库”。这可能是我看不到符号的原因吗？有没有办法告诉gdb从我的.so文件中查找符号？
