既知の問題¶
This is a list of known bugs in Spack. It provides ways of getting around these problems if you encounter them.
Variants are not properly forwarded to dependencies¶
Status: Expected to be fixed in the next release
Sometimes, a variant of a package can also affect how its dependencies are
built. For example, in order to build MPI support for a package, it may
require that its dependencies are also built with MPI support. In the
package.py, this looks like:
depends_on('hdf5~mpi', when='~mpi')
depends_on('hdf5+mpi', when='+mpi')
Spack handles this situation properly for immediate dependencies, and
builds hdf5 with the same variant you used for the package that
depends on it. However, for indirect dependencies (dependencies of
dependencies), Spack does not backtrack up the DAG far enough to handle
this. Users commonly run into this situation when trying to build R with
X11 support:
$ spack install r+X
...

Package cairo requires variant ~X, but spec asked for +X
A workaround is to explicitly activate the variants of dependencies as well:
$ spack install r+X ^cairo+X ^pango+X

spack setup doesn't work¶
Status: Work in progress
Spack provides a setup command that is useful for the development of
software outside of Spack. Unfortunately, this command no longer works.
See https://github.com/spack/spack/issues/2597 and
https://github.com/spack/spack/issues/2662 for details. This is expected
to be fixed by https://github.com/spack/spack/pull/2664.
