Because this seems random, it reminds me a known-issue we have: http://software.intel.com/en-us/articles/compile-time-error-cant-open-file-cuserslocaltemp772811srcs...
There is an internal option to help with this. Let me know if it is the case.
Yes. note for this optio though - it may change without notice.
So it's a different issue then. could youcheck the output window to see what caused the basic lib not being created? any error msg?
Under tools -> option dlg, what do you have for the value of "Max Number of Parallel Project Build" under "Build and Run"?
Let me also check if there is a known issue about it.
