因为可执行文件依赖于很多动态共享对象(DSO),这个时候,可执行文件对于很多外部符号的引用还处于无效地址的状态,即还没有跟相应的共享对象中的实际位置链接起来,所以在映射完可执行文件之后,操作系统会先启动一个动态链接器(Dynamic Linker)
这时候,可执行文件里对于很多外部符号的引用还处于无效地址的状态,即还没有跟相应的共享对象中的实际位置链接起来。所以在映射完可执行文件之后,操作系统会先启动-个动态链接器(Dynamic Linker)。 4.动态链接情况下 在Linux下,动态链接器ld.so实际上是一个共亨对象,操作系统同样通过映射的方式将它加载到进程的地址空...
linker开关 -Wl,--export=print_callee, 表示该wasm module会输出一个函数print_callee可以被调用 __wasm_call_ctors 是一个初始化函数, 常常被用来做一些module的初始化工作, 如果你的动态库有一些全局变量的使用, 很有可能需要在运行时做一个reloc的工作, 那就export这个函数吧, 否则会被编译器删除. callee2....

During the course of our extraction and review of the strings from our suspect file,sysfile, we discovered references to/lib/ld-linux.so.2, the ELFDynamic Linker/Loader and to the shared librarylibc.so.6,which is often a reference to the GNU C Library or as it is commonly referred, “...
Sections below explain how the runtime linker uses and changes the tables to create memory images for object files. The .hash section with type SHT_HASH that holds a symbol hash table.Shared objects can occupy virtual memory addresses that are different from the addresses recorded in the file'...

I figure that this is error comes from the dynamic linker when the system installed library is missing something our executable expects. I don't know much about the internals of the dynamic linking process ... and googling the topic doesn't help much. :( Anyone know what causes...
The QuarkslaB Dynamic Linker (QBDL) library aims at providing a modular and portable way to dynamically load and link binaries. Documentation See here. Quick example Here is a quick example using the Python API to run simple MachO binaries under Linux: import pyqbdl import lief import sys imp...
