Summary: Multiple chosen python modules are not built due to
missing header files in include path
Product: buildroot
Version: 2014.08
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
AssignedTo: unassigned at buildroot.uclibc.org
ReportedBy: cma at vtxnet.ch
CC: buildroot at uclibc.org
Estimated Hours: 0.0
Python doesn't build some of the requested modules because the setup.py script
is unable to locate the respective header files. The affected modules are
sqlite3, ssl, zlib and bsddb. The build completes successfully and the target
images are correctly generated, but these modules will not work in python.
Buildroot target is i686. Buildroot version is 2014.11-git-00330-g6712213.
Chosen modules in .config:
BR2_PACKAGE_PYTHON_BZIP2=y
BR2_PACKAGE_PYTHON_BSDDB=y
BR2_PACKAGE_PYTHON_CODECSCJK=y
BR2_PACKAGE_PYTHON_CURSES=y
BR2_PACKAGE_PYTHON_PYEXPAT=y
BR2_PACKAGE_PYTHON_READLINE=y
BR2_PACKAGE_PYTHON_SSL=y
BR2_PACKAGE_PYTHON_UNICODEDATA=y
BR2_PACKAGE_PYTHON_UCS2=y
# BR2_PACKAGE_PYTHON_UCS4 is not set
BR2_PACKAGE_PYTHON_SQLITE=y
BR2_PACKAGE_PYTHON_ZLIB=y
BR2_PACKAGE_PYTHON_HASHLIB=y
BR2_PACKAGE_SQLITE=y
# BR2_PACKAGE_SQLITE_READLINE is not set
# BR2_PACKAGE_SQLITE_STAT3 is not set
# BR2_PACKAGE_SQLITE_ENABLE_FTS3 is not set
# BR2_PACKAGE_SQLITE_ENABLE_UNLOCK_NOTIFY is not set
# BR2_PACKAGE_SQLITE_SECURE_DELETE is not set
# BR2_PACKAGE_SQLITE_NO_SYNC is not set
Relevant build log snippet (python-2.7.8-build.log:2878):
Python build finished, but the necessary bits to build these modules were not
found:
_bsddb _sqlite3 _ssl
_tkinter bsddb185 dbm
dl gdbm imageop
linuxaudiodev nis ossaudiodev
sunaudiodev zlib
To find the necessary bits, look in setup.py in detect_modules() for the
module's name.
After booting the target, importing these modules will result in an
ImportError:
# python -c "import sqlite3"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python2.7/sqlite3/__init__.py", line 24, in <module>
from dbapi2 import *
File "/usr/lib/python2.7/sqlite3/dbapi2.py", line 28, in <module>
from _sqlite3 import *
ImportError: No module named _sqlite3
Note: sqlite3 library is installed on the target and the sqlite3 shell is
working as excepted.
# python -c "import ssl"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python2.7/ssl.py", line 60, in <module>
import _ssl # if we can't import it, let the error propagate
ImportError: No module named _ssl
As a temporary workaround, copying the sqlite header file in the python include
directory before building python permits the module compilation (here for
sqlite):
$ cp output/build/sqlite-3080500/sqlite3.h output/build/python-2.7.8/Include/
For the other modules, I haven't tested.
