+# NumPy include directory - needed in all submodules
|
|
+# The chdir is needed because within numpy there's an `import signal`
|
|
+# statement, and we don't want that to pick up scipy's signal module rather
|
|
+# than the stdlib module. The try-except is needed because when things are
|
|
+# split across drives on Windows, there is no relative path and an exception
|
|
+# gets raised. There may be other such cases, so add a catch-all and switch to
|
|
+# an absolute path. Relative paths are needed when for example a virtualenv is
|
|
+# placed inside the source tree; Meson rejects absolute paths to places inside
|
|
+# the source tree.
|
|
+# For cross-compilation it is often not possible to run the Python interpreter
|
|
+# in order to retrieve numpy's include directory. It can be specified in the
|
|
+# cross file instead:
|
|
+# [properties]
|
|
+# numpy-include-dir = /abspath/to/host-pythons/site-packages/numpy/core/include
|
|
+#
|
|
+# This uses the path as is, and avoids running the interpreter.
