CMake Error at /usr/share/cmake/Modules/FindBoost.cmake:1128

I also have the gmp and gmp-devel packages installed. What should I change to get dorsal to find those?

I'm not sure DOLFIN uses GMP anymore, but, if you really need it, add -DDOLFIN_ENABLE_GMP:BOOL=ON to CONFOPTS in FEniCS/packages/dolfin.package. If GMP is installed in a non-standard location, you may also need to define GMP_DIR in your .platform file.

Regarding libboost_math_tr1: Have you tried to install the boost-math package?

BTW, I don't know much about Fedora, but should boost-openmpi-devel be listed among the packages that Dorsal assumes to be installed?

The only reason I mention it is because Dorsal noted it in the output. I'm
happy to ignore it if Doin no longer uses GMP.

I have that one installed. Maybe there's a *-devel package I'm missing.

Yes, I think you should add this one (I installed it after the first time I
got the boost_mpi error).

Thanks for your help. I will let you know if I find what Fedora package
hides the libboost_math_tr1. I have a math_tr1.hpp, but no library that I
can locate so far.

This failed build has the same error that I'm seeing: https://launchpad.net/~fenics-packages/+archive/fenics-dev/+build/2899860

"""

On Fedora the boost-devel package provides boos/math/tr1.hpp; but I haven't found any package that includes a libboost_math_tr1.so (if such a thing exists?).

I have looked into this and it seems that the Boost.Math libraries are not in any of the Boost packages in Fedora. The packaging file (http://goo.gl/oo37k) states that the Boost.Math library is header-only and that the package (boost-math) is empty:

180 %package math
181 Summary: Stub that used to contain boost math library
182 Group: System Environment/Libraries
183
184 %description math
185
186 This package is a stub that used to contain run-time component of boost
187 math library. Now that boost math library is header-only, this
188 package is empty. It's kept around only so that during yum-assisted
189 update, old libraries from boost-math package aren't left around.

This was changed early in 2010:

1152 * Thu Jan 14 2010 Petr Machata <email address hidden> - 1.41.0-2
1153 - Replace a boost-math subpackage with a stub

I guess Boost should therefore be built by Dorsal on Fedora. Harish?

The fedora platforms now build boost.

By "now", do you mean Fedora 16? As I mentioned above, on Fedora 14 all you get is the header. Fedora 14 just reached end-of-life last Friday (9 Dec 2011). Has anyone successfully built on Fedora 15 or 16?

Upgraded to Fedora 16. This seems to have worked:
./dorsal.sh FEniCS/platforms/supported/fedora15.platform

I spoke too soon. I get this error: OSError: The Boost math library was not found, trying to run 'python demo_navier-stokes.py'.

"yum info boost-math" gives:
Description :

So I'm left wondering (with my shiny new Fedora 16 install, very nice btw) for which values of "now" does Fedora build the libraries?

By "now" we mean that the latest Dorsal now builds boost on Fedora platforms (since the boost-math package in Fedora is broken).

Thank you Johannes; I understand what you mean now. I updated dorsal to the latest development version (bzr branch lp:dorsal), and executing the script does indeed grab and build the Boost libraries. I sourced the dolfin.conf file as stated at the end of the script output, and then tried python -i demo_navier-stokes.py.

I get:
  OSError: The Boost math library was not found.
  If Boost math library is installed in a nonstandard location,
  set the environment variable BOOST_DIR.

It looks like the boost libraries were installed in ~/Work/FEniCS/lib/. So I set BOOST_DIR=${HOME}/Work/FEniCS/lib, then export BOOST_DIR. I still get the same error when I try the demo.

What should I set the BOOST_DIR variable to? Should this be something that is set by dolfin.conf?

Sorry, the error I get now that I've set BOOST_DIR is different:
  OSError: The Boost headers was not found.
  If Boost is installed in a nonstandard location,
  set the environment variable BOOST_DIR.

Thanks Johannes Ring, that solved my question.
