I've added it to list of issues for the next release.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/toolbox-on-a-different-windows-drive-causes-a-failure-to-start-c-program#post-4363 Fri, 07 Mar 2014 16:53:41 +0000 KHO 4363@http://www.k-wave.org/forum/ <p>We came across another tiny bug, that only occurrs on very rare occasions.</p> <p>To reproduce it, a windows system with at least two drives is necessary (one can be a USB stick). If the toolbox is on one drive, but the (arbitrary) script that is executed is on the other, the execution using the C Binary fails, because the system cannot find the binary.</p> <p>The reason for this is the change directory command in the script <em>kspaceFirstOrder3DC.m</em></p> <p>Windows will change the directory, but since the current directory is on a different drive, the change will not take effect unless the drive is also changed. </p> <p>For example, if the toolbox is on the C drive ("C:\kwave-path\") and the script (and also the active directory of matlab) is on D ("D:\scripts\"), a command "cd C:\kwave-path\" will result in the current directory still being "D:\scripts". Only an additional "C:" as a command will result in "C:\kwave-path\" becoming the active directory.</p> <p>I would suggest simply adding the drive change to the command as well by extracting it from the <em>path</em> variable first. This is possible also by enabling the <em>/d</em> option of the cd command.</p> <p>The background of this odd behavior seems to be that windows allows for multiple active directories (one per drive). I don't see the benefit of this, since you still have to tell it which drive should be active, but that's how it is. </p>
