Shared project is compiled but output is sent to "nul" (Read 974 times)

	My solution builds, loads and runs (on R4 Minima) successfully on all machines except one. On this particular machine, the same codebase and project (pulled from GIT) fails to build. Specifically, each file in one of my shared projects, is successfully compile but for some reason the generated object file is being sent to "nul" i.e. the following flag is being used: -o "nul". As far as I can tell the VS and VMicro extension environments (all latest) are identical. What could possibly be causing this? Code i-g++" -c -w -Os -g3 -fno-use-cxa-atexit -fno-rtti -fno-exceptions -nostdlib... a\Debug.Messaging\DisconnectResponseMessage.cpp" -o "nul"

	If you set "vMicro>Global Options>Compaibility>Compile ALL Project Folder Sources" to FALSE.

	Thanks, yes I noticed that after I posted and remove the request about the build properties. Did you try changing the property I mentioned to "False"?

This worked even though the compiler still is using -o "nul". How strange is that? And why does it work on every other machine where this option is set to TRUE?

	The need to set that property to false is a bug in the last release due to be updated within the next couple of days. Your change will continue to work after the update. The NULL option relates to the deep search for libraries, not to the compiler. If your other machines have deep search disabled or have cached the previous deep search output then you won't see an attempt to run the NULL command in the output.

	OK. Thank you very much! Let's close this for now.
