Boost libraries?

[Steven DeCaluwe]

Okay, basic question, here - I’m trying to update my cantera installation, and keep getting the following error:

scons: Reading SConscript files ...

INFO: SCons is using the following Python interpreter: /usr/local/opt/python/bin/python2.7

Configuration variables read from 'cantera.conf' and command line:

    matlab_path = '/Applications/Matlab_R2012a.app'

    sundials_include = '/usr/include/sundials/include'

    sundials_libdir = '/usr/include/sundials/lib'

Checking for C++ header file cmath... yes

Checking for C++ header file fmt/ostream.h... no

INFO: Using private installation of fmt library.

Checking for C++ header file gtest/gtest.h... no

Checking for C++ header file Eigen/Dense... no

Checking for C header file sys/times.h... yes

Checking for C header file unistd.h... yes

Checking whether __GLIBCXX__ is declared... no

Checking whether _LIBCPP_VERSION is declared... yes

INFO: Found Boost version ''

ERROR: Boost could not be found. Install Boost headers or set 'boost_inc_dir' to point to the boost headers.

See 'config.log' for details.

This occurs whether I download the source code and build from scons, or build using homebrew (“brew install cantera --HEAD --with-matlab=/Applications/MATLAB_R2012a.app/ --without-sundials”).

A little confounding, since the installation instructions no longer mention needing boost, but even when I download and reinstall boost, it is not remedied.

Thanks for any help,

Steven

I had the same issue on my Mac (for the most recent cantera build) and I downloaded boost via homebrew and included this in the cantera.conf file:

boost_inc_dir = '/opt/local/include'

Hope this works for you as well

Steven,

The dev-docs (which are relevant for the HEAD commit) do mention that Boost is required: http://cantera.github.io/dev-docs/sphinx/html/compiling.html#other-required-software Can you send a link to the docs you're looking at, to make sure we've caught all the required places?

How did you install Boost? You'll need to set boost_inc_dir in cantera.conf to point to the include directory where the header files got installed.

Best,
Bryan

Steven,

If you install Boost using Homebrew (making sure that it is 'linked', not just in the 'Cellar'), it should be in /usr/local/include (not /opt/), in which case it should be on the default search path of the compiler and you should not need to specify boost_inc_dir. You can double-check that /usr/local/include is on the search path by running:

clang++ -E -x c++ - -v < /dev/null

and making sure that '/usr/local/include' appears in the list toward the end of the output from this command.

Right now, installing the development version of Cantera using Homebrew (using hte --HEAD option) is broken because Homebrew installs an old version of Cython that doesn't work with the current version of Cantera as part of the build process. I have already filed a Pull Request to fix that, so this should work again once that has been merged.

Regards,

Ray

Thanks for the update, Ray - I think I've been struggling with that very issue, the past 10-20 minutes (mixing and matching homebrew builds but then trying to build cantera from the source code… currently running into cython problems).

Boost is in fact in /usr/local/include, but the Homebrew install wasn't finding it (even when I added the link in my 'cantera.conf' file).  I'm guessing perhaps I didn't link it in Homebrew?  Not sure - 'brew doctor' does not indicate any problems, but knowing that the Homebrew install of the development version is currently broken, I'm not going to worry about that, at the moment, and just re-start the whole process from the source code.

Thanks again, to you, Bryan, and Santosh.

FYI - uninstalled and re-installed cython using pip, and the install from source code went smoothly, after that.

Thanks, all, for your help.
