Issue 1030250: distutils' dry-run wants to create some real build dirs (original) (raw)

[forwarded from http://bugs.debian.org/270127]

When using the distutils to build a python extension module while using the dry-run option the build fails. It goes like this:

frigg:/FEMesh/mesh$ ./setup.py --dry-run build running build running build_py creating build creating build/lib.linux-sparc64-2.3 creating build/lib.linux-sparc64-2.3/Mesh copying Mesh/init.py -> build/lib.linux-sparc64-2.3/Mesh creating build/lib.linux-sparc64-2.3/Mesh/Delaunay copying Mesh/Delaunay/init.py -> build/lib.linux-sparc64-2.3/Mesh/Delaunay running build_ext building 'Mesh.Delaunay._qhull' extension creating build/temp.linux-sparc64-2.3 error: could not create 'build/temp.linux-sparc64-2.3': No such file or directory frigg:/FEMesh/mesh$

build/temp.linux-sparc64-2.3/Mesh/Delaunay: frigg:/FEMesh/mesh$ rm -rf build/ frigg:/FEMesh/mesh$

This should show it all.

The third parameter to mkpath() is 'verbose', not 'dry_run'! Correction is trivial:
