Disallowed file accesses

[jyoungman19111]

I have an msbuild project that is getting an error when creating a pdb file. How can I fix this? Thanks.

BuildXL requires by default that all outputs (writes) be declared. Unfortunately symbol files are sometimes not considered "real outputs", so probably this write is not declared in the spec and you're getting these errors.

Some stuff you can try:

• Use the /Z7 switch for cl to inject the debug symbols into the object file (which will be a declared output for the process) instead of outputting to a (non-declared) .pdb.
• Untrack the cl.exe accesses to the v:\code\win32\Debug\pdb directory by adding it to an allowlist. Allow lists are meant for these cases but are a technically unsafe option because they may lead to non-deterministic builds. In your case the directory looks pretty safe to untrack because it looks only meant for symbol files anyways and will not affect the main build outputs.

Thank you for your suggestions. I am new to BuildXL and want to use it in our build. I was able to proceed by using the additionalOutputDirectories directive but now I’ve come upon a mismatch of “NTDDI_VERSION setting conflicts with _WIN32_WINNT setting”. Thanks.

Thanks for using and exploring BuildXL, it is much appreciated. Please send any valuable feedback our way so we can keep improving the user experience.

You last error looks more like a compilation error rather than being related to the build configuration, are you hitting it before the execution starts? Refer to the documentation for those headers: [1] [2] [3]

[jyoungman19111]

I’m still having trouble putting together a complete build. I have individual pieces working but a build from the root does nothing. Can you help with this? Thanks.
