Package: automake1.10
Version: 1:1.10.3-1
Severity: normal
AM_PATH_PYTHON from /usr/share/aclocal-1.10/python.m4 doesn't return the
right directory for Python 2.6 extensions on Debian: It returns
${prefix}/lib/python2.[67]/site-packages/ instead of .../dist-packages/.
This is because of /usr/share/aclocal-1.10/python.m4:98
AC_SUBST([PYTHON_PREFIX], ['${prefix}'])
which defines PYTHON_PREFIX as the un-expanded string '${prefix}'
Notice that this is quoted and does not get expanded!
This then gets passed to /usr/share/aclocal-1.10/python.m4:120
[am_cv_python_pythondir=`$PYTHON -c "from distutils import sysconfig; print
sysconfig.get_python_lib(0,0,prefix='$PYTHON_PREFIX')" 2>/dev/null ||
echo "$PYTHON_PREFIX/lib/python$PYTHON_VERSION/site-packages"`])
which then calls Python with the unexpanded '${prefix}'
/usr/lib/python2.6/distutils/sysconfig.py:110 just checks the prefix for
/usr and /usr/local, but not for '${prefix}', thus returning
'.../site-packages' instead of '.../dist-packages'
See the difference when calling it directly from commandline:
/usr/bin/python2.6 -c 'from distutils import sysconfig; print
sysconfig.get_python_lib(0,0,prefix="${prefix}")'
${prefix}/lib/python2.6/site-packages
/usr/bin/python2.6 -c 'from distutils import sysconfig; print
sysconfig.get_python_lib(0,0,prefix="/usr")'
/usr/lib/python2.6/dist-packages
(I switch ' and " for easier shell quoting)
dh_python2 later complains about the wrong directory, but moves the
files to the right directory, so this is currently not critical.
It would be nice if the interaction between python.m4 and
python/distutils/sysconfig.py could be fixed. I'm unsure if this is
acrually a bug in autoconf or python.
