gcc 链接器错误 : undefined reference to `__security_cookie'

Question

与 gcc我想建一个DLL ，它使用 Curl 库。

后

$gcc -shared -o GA_TestLibV11.dll GA_TestLibV11.o GA_TestLibV11.def curllib_static.lib

$ gcc -shared -o GA_TestLibV11.dll GA_TestLibV11.o GA_TestLibV11.def curllib_static.lib -llibws2_32

我收到以下警告(多次出现)

警告:.drectve `/manifestdependency:"type='win32' name='Microsoft.VC90.CRT' v

以及以下错误:

curllib_static.lib(./Release/easy.obj):(.text[_win32_init]+0x7): undefined reference to `__security_cookie'

curllib_static.lib(./Release/easy.obj):(.text[_win32_init]+0x41): undefined reference to `@__security_check_cookie@4'

collect2.exe: error: ld returned 1 exit status

我还需要链接什么来解决这些问题？

谢谢。

您将需要与 bufferoverflow.lib 库之一链接，

bufferoverflowU.lib This library implements functionality for securitycookie verification that can be used in the user mode and inapplications that use the Win32 API. Most applications link to thislibrary.

bufferoverflowK.lib This library implements the check of asecurity cookie that works in the kernel mode of the operating system.Services and subsystems that run in the kernel mode have to be linkedto this library.

bufferoverflow.lib This library implementsfunctionality for security cookie verification that can be used in theuser mode. However, bufferoverflow.lib is different frombufferoverflowU.lib because bufferoverflow.lib can be used in servicesand in applications that do not use the Win32 API.

或者，您将不得不在没有 /GS 的情况下重建 curl编译器开关，

In Microsoft Visual Studio 2002, a new compiler switch that is named "/GS" has been introduced to the Microsoft Visual C++ compiler. Whenthe " /GS" switch is set, the compiler injects buffer overrundetection code in the compiled code.
