<p class=MsoPlainText>Hello<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Having read the papers on Nested Data Parallelism in the
Haskell I wanted to play around with the de-sugared implementation in the GHC
library NDP. I have built GHC from source, on RHE5, and then installed the NDP
library from the tar ball. Following the build instructions in the README I got
to building the library which resulted in the following error being reported:<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>ghc-6-6.1: combination not supported: Threaded/Profiling<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>This seems to be down to the fact that -prof and
-threaded have been specified on a particular build line, although I emit not
to be completely sure about this.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Looking through the GHC page on its SMP support it seems
to imply that the option -threaded is not needed when building code, rather
when linking a parallel program, but it is unclear if this is the case when
building a library such as NDP. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Having scanned through the GHC source tree it seems that
-prof is referenced in numerous places such that it would be a bit of a pain to
have to remove these over removing the single reference to -threaded in the
ndp.mk file. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thanks for any help that you can provide on this.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Many Regards,<o:p></o:p></p>
