如何在 Ubuntu 上使用 DSFML2 和 D2 解决链接器错误？

Question

我正在运行带有 DMDv2.052 的 64 位 Ubuntu Linux，试图让应用程序与 DSFML2 一起工作，但我不断遇到链接器错误。

我使用共享库+发布版本构建了 SFML 和 CSFML 库，并安装了它们，然后构建了 DSFML 绑定，如下所示：

me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/system$ dmd -m64 -lib *.d -of../../../lib/libdsfml-system.a 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/system$ cd ../window 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/window$ dmd -m64 -lib *.d -of../../../lib/libdsfml-window.a 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/window$ cd ../graphics 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/graphics$ dmd -m64 -lib *.d -of../../../lib/libdsfml-graphics.a 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/graphics$ cd ../audio 
me@lappy486:~/devl/sfml2/bindings/d/import/dsfml/audio$ dmd -m64 -lib *.d -of../../../lib/libdsfml-audio.a 

当尝试构建项目以使用它们时，我收到以下错误：

me@lappy486:~/devl/d/Gossamer$ dmd -m64 *.d game/*.d graphics/*.d -L"-L/home/me/devl/sfml2/bindings/d/lib -ldsfml-system -ldsfml-window -ldsfml-graphics -ldsfml-audio"

有人可以帮忙吗？我还没能让它发挥作用。

Answer 1

我不知道出了什么问题，但我首先要消除所有可能的复杂性：

1. 在 D 中使用 .so 是...“有问题”，如果可能，请使用静态链接。
2. 尝试以 32 位模式构建它（我上次听说 64 位仍然是 alpha）
3. 尝试使用相同的 lib 设置构建一个 hello world 应用程序。
4. 不要从 DMD 进行链接，而是通过 ld 显式进行链接。 （编译已经在详细模式下运行的内容，以获得您需要的命令行的起点。）
