Hi all,
I need some help with building Boost.MPI. My system is a Debian testing (lenny) system and I'm following the instructions at [lenny uses 1.35 and not 1.36]:
... [snip]
Firstly, I'm not sure if I have everything installed... But I also don't know what the "top-level Boost directory" is. I've tried these locations:
/usr/share/boost-build/ /usr/share/boost-build/build/ /usr/share/boost-build/tools/ [it had an mpi.jam file in it] /usr/include/boost/
Ray,
I think your trouble is with the "top level directory." It is the directory that holds the initial boost download. It has things in it like a directory called "boost" (that holds the actual code for the libraries), one called "doc" (that holds a few documents, but not most of them), one called "lib" (that holds most of the documentation and examples for the libraries), and most importantly the top level jamfile for bjam to create boost libraries. That is where you need to be when you run bjam to make the MPI library. The rest sounds like it is probably fine, and we can look at it more closely if this doesn't work.
Thanks for the tip! I did more searching and as I installed from the official Debian packages, there doesn't seem to be a directory structure like this. i.e., documentation is in /usr/share/doc, it seems. I guess this is standard for Debian packages. Anyway, I thought I'd Google more as maybe I'm missing a package. As it turns out, as late as July 2008, someone has reported a bug [in the libboost1.35-dev package, for anyone interested] that says the Jamfiles are missing. :-( Maybe something further up (i.e., Debian unstable) might have it, but I don't think I want to be using anything from "unstable" with my limited knowledge. Is it terribly hard to download Boost 1.35 [again, because that is what Debian testing is using], take the Jamfile and edit it for my purposes (but not get it "perfect" enough for distributing to someone else)? I downloaded 1.36 and am looking at the Jamfile [I see what you mean now...if I had downloaded the source, the Jamfile just jumps out at you...can't miss it] -- looks difficult, but not impossible. But I'm sure there's plenty of non-Debian-specific information out there on how to do this. Or maybe I should just go with installing from source into a separate directory. This latter option seems easiest right now, I guess... Thanks a lot for your help, John! Ray PS: Link to the bug report -- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=490380
