英文:
angr - project.loader.find_symbol("main") does not works on Windows
问题
我有一个非常简单的C代码 - 在MSVC上使用clang++编译器编译。当我在angr环境下运行它时 - 它简单地找不到main()函数，而对于其他像strcmp等函数，它可以找到。此外，在Linux（g++）下运行相同的程序没有任何问题。
另外，我可以在dumpbin.exe、gdb、x64dbg等工具中看到main()符号。
path_to_binary = "D:\\angr_project\\angr training\\angr_ctf\\00_angr_find\\00_angr_find.exe" # :string
print("Started execution")
project = angr.Project(path_to_binary, load_options={'auto_load_libs': False})
main_fn = project.loader.find_symbol('main')
if main_fn:
print("main found")
else:
print("main not found")

查看cle.pe的get_symbol源代码。它从导出表中获取信息。
看来angr不支持PDB。
英文:
See the cle.pe's get_symbol source code.
It gets from the export table.
It seems that angr doesn't support PDB.
