System.IO.PathTooLongException

[Noah]

Hello,

I am running into the following path length error, it looks to be something within the cmake cache of visualgdb:

-- Generating done (1.9s)

========== Project Configuration Summary ==========
<strong>*****</strong> configured in 00:13
========== Configuration: 1 Succeeded, 0 Failed, 0 Skipped ==========

Note that I have obscured some details, in bold. It looks like the json file name is the full CMake module include trace, which inevitably produces a huge file name.

This error seems to cause a ‘clean rebuild’ every time I build, presumably because the build system does not believe that the previous clean rebuild was successful, even though it is).

I have long-file-names enabled on my computer and no errors appear in the visualgdb diagnostics console. I am also using a ReFS dev drive.

 

Thank you for your help,

Noah

I also found that the file that it is looking for in the CodeModelCache,

directory-modules.hal_nxp.mcux.mcux-sdk-ng.devices.RT.RT1064.MIMXRT1064.devices.RT.RT1064.MIMXRT1064.drivers.devices.RT.RT1050.MIMXRT1052.drivers.flexram-DEBUG-532024778a5771ea2c83.json

does not seem to exist.

The file does exist in

<PathToBuildOutput>\VisualGDB\Debug\.cmake\api\v1\reply
