	I think spawned processes would run as admin too but there is an easier way to test with admin mode... I am trying to rule out a permissions issue. I notice arduino is building off the temp folder. You can tell visual micro to do same. Please set "Tools>Options>Visual Micro>Compiler>Build Cores Folder" to this folder then build C:\Users\mafav\AppData\Local\Temp\vmicro\core Thanks

	Build Cores Folder set as indicated, then project cleaned and rebuilt. Same problem as usual. I include the file. Patrizia

	Don't know whether may be of help, but in the moment I'm using a Teensy 4.1, in debug mode. Compilation under Visual Micro completed successfully. Is the inconvenient possibly specific to "some" boards and not others?

	Thanks. It is an issue related to the string.cpp in the mbed core. That's why teensy builds okay. The attached can be run from cmd prompt. The only change is to uppercase the c:\ and swap the quotes outside of the -I params. Neither of which should have any effect at all. However, it would be useful to rule out those things with this test.

	Command executed: job completed successfully (no error indication) in about 1s. (FYI: in the project I'm involved in I switched from Portenta to Teensy, and use it with Visual Micro infrastructure: so, please do not feel some special pressure. For me it was a problem in "important .AND. urgent" class. Now it is just "important" (but also my (not Arduino-related) "data-driven advection-diffusion particle model" is, and is quite late, so I will not cry if analysis will require some time ) (anyway, I'm here, and will continue to provide you feedback as needed - I'm really curious, on one side; on the other, we all are responsible of the working of engineering objects...)

	Thanks, we are just intrigued. Are you working on a case sensitive operating system?

	No, it's a regular (although used since a lot of time) Windows 11 (formerly 10) machine. Operates case-insensitively. It has many app installed, so the environment string is quite overfull. I could consider removing some stuff however, would that be a problem.

	Ok thanks. It is a simple command to compile a single file. You don't need to change aything. Does the attach work or fail with error?
