Sphinx executable not found with cmake 3.2

[Philipp Hübner]

Hi,

it seems to me that with cmake 3.2.2 (instead of 3.0.2) ceres solver fails to find the sphinx executable,
which hasn't changed and is /usr/bin/sphinx-build.

These are the relevant lines from the log:

[...]
-- Building Ceres as a shared library.
-- Enabling CERES_USE_OPENMP in Ceres config.h
-- Enabling CERES_HAVE_PTHREAD in Ceres config.h
-- Enabling CERES_HAVE_RWLOCK in Ceres config.h

-- Enabling CERES_TR1_MEMORY_HEADER in Ceres config.h
-- Enabling CERES_TR1_SHARED_PTR in Ceres config.h
-- Enabling CERES_USING_SHARED_LIBRARY in Ceres config.h
-- Documentation building is enabled

-- Configuring incomplete, errors occurred!




Help greatly appreciated!

Philipp,

I can’t replicate this issue on OS X, albeit with 2.8.12.2 & 3.2.2, I assume you are running some version of Debian?  FindSphinx is pretty basic, and there aren’t any changes between CMake 3.0 & 3.2.2 that should break it.

I take it you are starting from a clean build directory for Ceres after updating CMake?  I would expect you to see some other warnings / errors related to a CMake version mismatch if this was not the case, but if not then perhaps this might be due to some old CMake cache data.

I'm using git-buildpackage with pbuilder/cowbuilder on Debian Sid, this
means I'm using a clean Debian chroot each time I attempt to build the
debian package I created.
But something's wrong with that combination at the moment.

For comparison I tried building on my own system without
pbuilder/cowbuilder, and it works like it should (and did before).

So you were right that it has nothing to do with cmake (or ceres solver).

Thanks!
