There is a problem with our design.<br>
<br>
If the user has used --download-xxxx and then later deletes everything in $PETSC_ARCH/lib then the next use of --download-xxx will fail because it will find the file<br>
in $PETSC_ARCH/conf/xxxx that indicates the last download succeeded but the libraries won't exist so the check for the packages libraries fails with a not particularlly useful error message.<br>
<br>
How can we fix this? Not just check for $PETSC_ARCH/conf/xxxx but also check for $PETSC_ARCH/lib/libs associated with xxxx before deciding to rebuild? Shoot the user who deletes everything in $PETSC_ARCH/lib?<br></blockquote>
<div><br></div><div>I am against additional checks, which are always fragile and provoke more pain than they dismiss. However, we</div><div>can improve the error message. After the 'conf' check, we remember that the library should be installed. If its not</div>
