Error: Cannot specify -o when generating multiple output files

[netx123]

VS2019 16.8.5
CPT 7.01

I have found that for some projects, both Tidy and Compile fail with the following error message:

--- CLANG COMPILE STARTED ---

PROJECT: F:\REDACTED\redacted.vcxproj [Release|x64]
clang++: error: cannot specify -o when generating multiple output files
Errors encountered during PCH creation

--- CLANG COMPILE FINISHED ---

I have not yet been able to identify anything special with these projects that might be triggering this issue.

Hello @netx123

A verbose log here would be very helpful. You can activate it from the Clang Power Tools setttings pane. Please attach it to this thread.

Also, can you make a stripped-down version of the project that we can work with in order to investigate this? That would be very helpful.

[netx123]

The issue occurs when using the latest LLVM (12.0.0) snapshot.

If i switch CPT back to use LLVM 11.0.0 the issue goes away.

I do not yet have a stripped down project, but I have been able to create a verbose log for you:

Hello again @netx123 ,

Can you please retest this scenario now that the public release of LLVM 12.0 is available?

Thank you.

[netx123]

Hi @hero101111 , I've tried again using the public release of LLVM 12.0 and I receive exactly the same error as before.
Interestingly I also tried adding the 12.0.0 version through CPT->Settings->LLVM->Add Existing LLVM , however browsing to the folder "C:\Program Files\LLVM\bin" did not display any error messages, however it failed to insert LLVM 12.0.0 into the list of available LLVMs as I would have expected.

[hero101111]

Hello @netx123 ,

This issue has been addressed in the latest Clang Power Tools release (v7.4.0). It brings support for LLVM 12.
Thank you for bringing it to our attention, your feedback has been very helpful.

Regards,
Gabriel.
