Hi,
Recently, my advocation for ggooooooggggling has been questioned !
I offer a proof by demonstration ;-)
IPO stands for the InterProcedural Optimizer.
This is a stage of compilation that many compilers including ifort may
invoke depending on the optimization level. Sometimes these intermediate
compilation stages produce scratch files. Thus, straightforward
suggestions are to make clean, remove scratch files (ifc was fond of
creating files with names like ifc2wKeIf), turn down the optimization level
via -O1 or -O0, etc.
Now because of my advocation for ggooooooggggling, I didnt stop here; I put
IPO link: can not find "("
into the search bar. Behold! The first hit was to intel with some IPO
C++ known problem; the next hits did not look promising. So I added
ifort to the front of the previous search.
Whamo!!!! A bevy of birdies were hit:
The first hit is a bloody condor:
http://softwareforums.intel.com/ids/board/print?board.id=11&message.id=2749&format=one
The fourth one is to an Amber Reflector post.
The fifth hit is another raptor; it leads to an intel page:
