__libc_start_main()初始化运行环境后,调用main()函数执行 另外,我们可以自定义程序的入口函数,gcc提供-e选项,用于在链接时指定入口函数,自定义入口函数时,必须使用选项-nostartfiles进行链接。 【拓展】链接器有多种方法设置进程入口地址(编号越前,优先级越高): -e输入命令行选项; 链接器控制脚本中的ENTRY(symb...
delay-loaded DLL. Other cases include static TLS (thread local storage), declared using__declspec(thread), which isn't handled when the DLL is loaded viaLoadLibrary. Dynamic TLS, usingTlsAlloc,TlsFree,TlsGetValue, andTlsSetValue, is still available for use in either static or delay-loaded ...
A helper program for linking dynamic executables. Typically, the kernel loads this program because it's the PT_INTERP of a dynamic executable. This program can also be run directly to load and run a dynamic executable. The executable can be inside a zip file if it's stored uncompressed and...
LINK.exe links Common Object File Format (COFF) object files and libraries to create an executable (EXE) file or a dynamic-link library (DLL).The following table lists options for LINK.exe. For more information about LINK, see:Compiler-controlled LINK options LINK input files LINK output ...
patchelf --set-rpath /opt/my-libs/lib:/foo/lib program This causes the dynamic linker to search in/opt/my-libs/liband/foo/libfor the shared libraries needed byprogram. Of course, you could also set the environment variableLD_LIBRARY_PATH, but that’s often inconvenient as it requires a...
One of the libraries that makes up my application depends on -undefined dynamic_lookup to link, and has since at least Snow Leopard if not earlier. I think iOS hasn't liked this for a while, but with the new linker I'm getting deprecation warnings even on OS X. I don't entirely und...
