No files created on build runner

I am using the runner on a windows machine using the shell to execute a make file.

When running the make file from a command line everything works. When run from a runner it goes through the build process but no output files are generated, as a result the build fails when it gets to the link.

Is there some sort of permissions issue with the runner, it is a service running as SYSTEM so should it not have access to all user space?

OK, I have found my problem. I didn’t realise that each build output is put into a separate folder to the source. Because I had a custom linker script with absolute paths in it then it didn’t work. Changing this to relative paths meant that the re-directed build output was now successfully linked.
