If an alternate compiler is specified, then check if this is actually
executable before assigning it so that we don't end up with specifying
an empty name to CMake. If the path does not exist, it will be preserved
so that CMake will complain with an easily identifiable error message.
Previously, specifying the compiler name with a variable
to configure ("configure CC=gcc") lead to CMake complaining
that <builddir>/$CC was not a valid path. This patch fixes
this by extracting the full path with "which <compiler>".
Should fix issue #355.
As of 2013-09 the DUNE code that reads dune.module is not MultiArch-
aware. Thus, for a 64-bit platform it will look in lib/ on Debian and
lib64/ on RHEL.
Some components are not yet MultiArch-aware and installs to either
lib/ (Debian) or lib64/ (RHEL) on 64-bit platforms. If we need to
interface with these components, then it is nice to have such a
variable set together with the regular detection code.
There is some code in place now to create wells for the no-deck case,
but since it does not work correctly yet, the simulator intercepts this
and throws.
this is required to use the exception code of opm-core in
opm-material. Also, the Dune prerequisites of opm-material can be
removed once PR #345 is merged into opm-core...
If we have checked out a newer Eigen3 directory in a sibling directory
to ours, assume that this is because the system version is obsolete and
that we want to use this one instead.
Eigen3 is a template-library, so we must compile the source code
directly together with ours instead of linking to a library.
If the build script gives us the location of a "built" Eigen3,
meaning a directory in which CMake has been run, locate the true
source directory from the cache entries.
The previous version may have ended up in lib64/ instead of lib/;
now we remove the arch-specific suffix from the path, and always
use the no-arch version.
dune.module does not contain any paths to architecture-specific
binaries. It is therefore always installed in no-arch lib/ directory.
Thus, there is no need to have a variable for this, and there was
no other users of this variable either.
If Boost is installed in say /usr/include/boost141 and
/usr/lib64/boost141, then there is no root you can specify to pick
them both up. However, whereas Autotools uses --with-boost and
--with-boost-libdir, FindBoost in CMake changes to using two different
variables: BOOST_INCLUDEDIR and BOOST_LIBRARYDIR. Using the header
directory for BOOST_ROOT will not work (in particularily not with
old CMake versions).
CMake does not like that you specify the compiler with the environment
variables, instead preferring that you set them as cache variables.
This layer translate between the names of the the two.
