windows - 如何在 Windows 中使用 Waf 引用本地 DLL？

Question

在 example given in The Waf Book 之后,我有下面描述的设置，它构建了一个共享库和一个静态库，然后将它们链接到一个 exe。我的系统是使用 VS2013 MSVC 运行 Windows 7。

当我使用示例 wscript 构建时，构建失败并显示:

Build failed
-> missing file: 'D:\\src\\waf-example\\demo\\build\\lib1.lib'

我注意到，尽管使用了 bld.shlib(它添加了一个任务来构建共享库，名为“lib1”，来自 a.c)，但构建输出显示同时一个 DLL 和一个 LIB 条目，而我只希望有一个 DLL 条目。

[5/8] cshlib: build\a.c.1.o -> build\lib1.dll build\lib1.lib build\lib1.dll.manifest

Waf Book 显示了没有此问题的 Linux 系统的构建输出:

[6/8] cshlib: build/a.c.0.o -> build/liblib1.so

我该如何解决这个问题？谢谢。

来自 The Waf Book 的 wscript

def options(ctx):
    ctx.load('compiler_c')

def configure(ctx):
    ctx.load('compiler_c')

def build(bld):
        bld.shlib(
                source = 'a.c',
                target = 'lib1'
                )

        bld.stlib(
                source = 'b.c',
                use    = 'cshlib',
                target = 'lib2')

        bld.shlib(
                source = 'c.c',
                target = 'lib3',
                use    = 'lib1 lib2')

        bld.program(
                libpath='.',
                source = 'main.c',
                target = 'app',
                use    = 'lib3')

看来 waf 需要您指定一个 .def file对于 Windows 上的共享库。使用 .def 文件是一种很好的做法，但不应该是强制性的，所以这可能是您发现的 Waf 中的错误。

我刚刚将 lib1 和 lib3 目标更改为:

bld.shlib(source = 'a.c', target = 'lib1', defs = 'a.def')
bld.shlib(source = 'c.c', target = 'lib3', 
          use = 'lib1 lib2', defs = 'c.def')

def 文件只是像这样的虚拟文件:

EXPORTS
    foo

这似乎足以让构建运行。
