"Dennis Jones"
Just prior to the error, the following is visible:
c:\source\3rdParty\boost\boost_1_34_0\tools\jam\src>.\bootstrap\jam0 -f build.jam --toolset=borland "--toolset-root=C:\Program Files\Borland\CBuilder5\Bin\..\ "
Indicating that a path containing spaces ("Program Files") apparently confuses the script.
The lack of responses to my query indicates that either nobody knows the answer or I am the only person that thinks this is a problem. If this really is a problem, I would have expected Boost developers to comment or suggest alternative solutions. On the other hand, if it is not a problem, I would have expected someone to quickly point out an error in my use of the script. But neither has happened, so I'm left wondering... Can anyone offer any insight, or confirm or reject my assertion that a problem exists? - Dennis
