Question

我正在尝试使用Xoreax Incredibuild（v 8.01）使用“BuildConsole”来建立LLVM解决方案文件，但我没有看到构建时间有任何加速。

在LLVM日志中，我可以看到消息达到的最大并发构建数。等待构建完成
我相信这可能是我没有看到使用Incredibuild构建LLVM的好处的原因。
Incredibuild用于构建解决方案文件的Visual Studio版本是2015。

有没有其他人遇到过这样的消息，如果有的话是什么原因/解决方案？

我还尝试使用 IB_profile.xml 文件来构建LLVM，看看它是否有助于摆脱上述消息但在使用XML文件将Incredibuild与LLVM集成时，我看到了相同的消息。

这是我使用构建带有Incredibuild的LLVM 的 Make命令：

BuildConsole LLVM.sln /build "Release|x64" /prj="INSTALL" /AvoidLocal=On /profile=IB_profile.xml

这是 IB_profile.xml文件：

的内容

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Profile FormatVersion="1">
  <Tools>
    <Tool Filename="devenv"  AllowIntercept="true" AllowRemote="true" AllowPredictedBatch="true" VCCompiler="true" OutputFileMasks="*.exe,*.dll" />
    <Tool Filename="cl" AllowRemote="true" AllowPredictedBatch="true" VCCompiler="true" OutputFileMasks="*.exe,*.dll" />
  </Tools>
</Profile>

以下是 LLVM日志的摘要：

BuildConsole LLVM.sln /build "Release|x64" /prj="INSTALL" /AvoidLocal=On /profile=IB_profile.xml

我的名字是Yoni Davidson，我来自IncrediBuild支持团队。使用BuildConsoel构建LLVM解决方案不应该需要profile.xml，因为它是Visual Studio解决方案，IncrediBuild应该处理它。因此，您可能没有远程计算机（Helpers）和/或您可能没有足够的并行任务，因此性能或多或少与Visual Studio一样，因为一切都在本地运行。 “达到最大并发构建数”意味着您尝试使用IncrediBuild启动另一个构建，而前一个构建仍在运行。这是不允许的，因此，您收到此消息。无论如何，这不是您拥有构建性能的原因。

我很乐意帮助您解决这个问题所以我建议您直接与我们联系：support@incredibuild.com或者只需右键点击IncrediBuild托盘图标 - ＆gt;联系支持。

期待您的回复。
