You're using something that is tied to what's used in EPICS that dates from a while back.  I'm not an EPICS user, but I know "GeSys" is some sort of "generic system" for RTEMS on EPICS.  Again, EPICS is at

When you executed "mkdir(test)" without quotes around "test" you created a directory on whatever you are using as a file system that used the address of the symbol "test" as a character string and the "mkdir" function dutifully created that directory.  Don't worry about that, if you figure out how to use the system you can get rid of it.  Actually, "rmdir(test)" (without quotes around test) will probably remove it.

I'm getting very curious.

- What is the application?  What does "alt-rotator" do?
- "cexpr" expects C language a C language compatible command line, your "mount -t.." command will definitely not work.  If you are not a C language programmer you face a major challenge and will need an awful lot of help to continue.
- I'm really interested: How did you inherit this application and what do you need to do?
- The function I suggested you try wasn't "ikup", it was "lkup".  That's short for "look up".  Try 'lkup("mount")' and see what you see.
