在Visual Studio中构建和链接V8

Question

我正在努力弄清楚如何在Windows上构建Google的V8.

到目前为止,我有:

• 已安装depot_tools
• 获取v8: fetch v8
• 创建项目文件: gn gen --ide=vs2015 out/Default
• 在VS2015中构建了整个解决方案

我的问题是,这只会产生大量.obj文件而没有.lib文件.

我已将项目(v8,v8_base,v8_libbase等)设置为Configuration type: Static library (.lib):

我不确定如何让Visual Studio生成库文件.任何帮助赞赏!

更新

我已设法使用以下步骤生成库文件:

• 打开VS Developer命令行
• 导航到包含OBJ文件的目录v8_base,v8_libbase,v8_external_snapshot和v8_libplatform.
• 对于其中的每一个.lib,使用lib命令手动构建,例如lib /o:v8_base *.obj
• 将所有这些lib文件复制到一个目录中icui18n.lib和icuuc.lib(这些在构建期间创建得很好.)

我现在正试图实际使用这些库,并遇到一个新的问题,我将非常感谢帮助.我在VS中链接了以下库:v8_base.lib; v8_libbase.lib; v8_external_snapshot.lib; v8_libplatform.lib; icui18n.lib; icuuc.lib; winmm.lib;但是我遇到了一些未解决的符号问题:

所有错误似乎都与v8::sampler- 任何帮助再次受到赞赏!

Answer 1

看起来我又在回答我自己的问题了。我希望我在问题中列出的信息对像我这样与过时文档苦苦挣扎的人有用。

我的更新涵盖了所需的所有内容，除了我什至没有注意到该v8_libsampler项目并且忘记为其生成库文件这一事实。一旦我做到了这一点并将其链接起来，我就可以启动并运行了！
