Hi Michael,

I have created the trace files for remote compile and rgrep for you and attached them.
For the remote compile I invoke a shell script called 'my_remote_compile.sh', which in turn calls a script 'my_compile.sh'. The script is called with two arguments, the build directory and the target name, which are lost, when the script is actually called. This works in Emacs 27.1.
For the rgrep invocation I simply used a pattern 'mytest' and '*' for the file pattern.

Regarding the error message about recursive invocation, I have not seen this anymore.

Best Regards,

Martin
