I am trying to use Xoreax Incredibuild(v 8.01) to buid LLVM solution file using “BuildConsole” but I am not seeing any speedup in the build times.
- In the LLVM logs I can see a message Maximum number of concurrent builds reached. Waiting for a build to complete
- I believe this could be the reason that I am not seeing the benefit of using Incredibuild to build LLVM.
- Version of Visual Studio used by Incredibuild to build the solution file is 2015.
Has anyone else encountered such a message and if so what is the reason/solution?
I have also tried using IB_profile.xml file to build LLVM and see if it helps in getting rid of the above message but I am seeing the same message when using XML file to integrate Incredibuild with LLVM.
This is the Make command that I am using to build LLVM with Incredibuild:
BuildConsole LLVM.sln /build "Release|x64" /prj="INSTALL" /AvoidLocal=On /profile=IB_profile.xml
This is the content of IB_profile.xml file:
<?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>
Below is the snippet of LLVM logs:
BuildConsole LLVM.sln /build "Release|x64" /prj="INSTALL" /AvoidLocal=On /profile=IB_profile.xml

My name is Yoni Davidson and I am from IncrediBuild support team. Building the LLVM Solution using BuildConsoel shouldn't require profile.xml since it is a Visual Studio Solution and IncrediBuild should handle it. Therefore, it is possible that either you dont have remote machines (Helpers) and/or perhaps you dont have enough parallel tasks so the performance is more or less as you have with Visual Studio since everything runs locally. The "Maximum number of concurrent builds reached" means that you are trying to start another build with IncrediBuild while the previous one is still running. This is not allowed and therefore, you receive this message. In any case, this is not the reason for the build performance you have.
I will be happy to assist you with this problem so I suggest that you will contact us directly: [email protected] or simply right click on IncrediBuild tray icon -> contact support.
Looking forward hearing from you.
