Hi Rikki,

  No, it is not working, rather getting an error, and the user i 
executed is the root user. if i compile the program as dmd 
<program name> and then execute it as ./<program name> it works 
fine, so is rdmd not supported in Linux.

Error:
/tmp/dmd_runqfz3ul: Permission denied

That sounds like your /tmp is mounted with noexec. which won't work with
rdmd or any other program that expects to be able to create a file in /tmp
and run it. Presumably, you'll need to change the settings in /etc/fstab so
that /tmp is not mounted with noexec.

Hi Jonathan,

   Yes the /tmp is mounted with noexec option , we should not 
change this option as it is a security violation so is there any 
other way we can make it work, it tried setting the tmp env 
variable to a local FS which is mounted with the noexec option 
but it did not work.

Modify rdmd to use another directory which is more acceptable for your 
setup.

Or just set an environment variable like TMP, if you don't want 
to append the flag Jonathan gave each time, as rdmd simply calls 
std.file.tempDir:

Whether it's really a security risk is up for debate, though I'm sure that
concerns over that would be why /tmp is mounted with noexec on your system.

Looking at rdmd --help, it does list a --tmpdir flag, so if you have another
directory that is not mounted noexec where you would consider it acceptable
to have temporary files be created and executed, then you can use --tmpdir
to tell rdmd to use it. So, presumably, the shebang line would then be
something like



though I haven't tested it.
