D2 gdc 链接错误 - 对 `_D3std6stdint12__ModuleInfoZ` 的 undefined reference

Question

我正在使用 https://bitbucket.org/goshawk/gdc/downloads/gcc-4.5.2-tdm-1-gdc-r575-20110723.zip使用 TDM GCC 4.5.2 在 -v2 模式下构建 DLL。在我做的一个模块中import std.stdint .所以我想我应该链接到 libgphobos2 来解决这个问题，但它给了我更多的错误:

这是一个错误还是我需要向 gdc 传递一些额外的标志？

Answer 1

我还在 -v2 模式下尝试使用来自 bitbucket 源的 GDC 来编译库，以尝试将某些 D 功能与 C++ 应用程序接口(interface)。

我发现缺少指向 _tlsstart 和 _tlsend 的链接也存在同样的问题。
部分解决方案是在库中包含一个“main”函数:

void main(){}

我正在使用 linux 上的静态库。我检查了生成的静态库:

nm libDexample.a

这表明上述简单的 main 向 libDexample.d 中插入了额外的符号(也最终出现在 c++ 可执行文件中):

_Dmain
_tlsend
_tlsstart

当然，如果在 D 应用程序中使用该库，这些符号会给出与多个定义相关的链接错误。因此，您可以定义一个单独的库，例如 libtls.d，其中包含:

extern(C) void make_it_link_please(){}
//inserts the _tlsstart and _tlsend stuff???????
void main()
{
}

在 C++ 应用程序而不是 D 应用程序的情况下与 libtls 链接。
