Python argument types in DatasourceCache.register_datasources(str) did not match C++ signature #103

filotti · 2016-06-13T19:52:15Z

Hi,

I'm trying to build mapnik with python bindings on Ubuntu 16.04. I cloned the mapnik and python-mapnik repositories, installed all the required dependencies, and compiled both projects successfully.

But when I try to import mapnik from python, I get the following error:

Python 2.7.11+ (default, Apr 17 2016, 14:00:29)
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import mapnik
Traceback (most recent call last):
File "", line 1, in
File "mapnik/init.py", line 1075, in
register_plugins()
File "mapnik/init.py", line 1057, in register_plugins
DatasourceCache.register_datasources(path)
Boost.Python.ArgumentError: Python argument types in
DatasourceCache.register_datasources(str)
did not match C++ signature:
register_datasources(std::string)

I tried again with a fresh Ubuntu 15.10 install, and I got the same error. Then I tried again on Centos 7 and it worked.

I noticed that the libboost versions were different, 1.58 for Ubuntu and 1.53 for Centos.

gunjanmodi · 2016-06-22T13:34:57Z

For me, on Ubuntu 15.10, I am getting the same error while running testcase python setup.py test as well as on doing import mapnik

File "python-mapnik/mapnik/__init__.py", line 1075, in <module>
    register_plugins()

  File "python-mapnik/mapnik/__init__.py", line 1057, in register_plugins
    DatasourceCache.register_datasources(path)

+1 Im also getting this error

Regressor · 2016-07-08T13:39:45Z

Got this error too trying to install python-mapnik on ubuntu 16.
Also I tried apt-get install python-mapnik and got link error at python - import mapnik.

Is there any way to get working mapnik on ubuntu16 ?

bsamorodov · 2016-07-21T09:48:09Z

Import mapnik works for me, but running the example world.py does not (with the error similar to the OP's one):
Traceback (most recent call last): File "world.py", line 6, in <module> polygon_symbolizer = mapnik.PolygonSymbolizer('#113355') Boost.Python.ArgumentError: Python argument types in PolygonSymbolizer.__init__(PolygonSymbolizer, str) did not match C++ signature: __init__(_object*)

This result I get with the latest python-mapnik <origin/master> code at both:

CentOS-7, boost-1.53.0-25.el7, mapnik-g85a6ef9 (as of 2016-07-19)
FreeBSD-12, boost-1.55, mapnik-3.0.9.

bsamorodov · 2016-07-27T14:02:27Z

I went ahead, at CentOS-7. I built and installed boost-1.61, recent mapnik, python-mapnik. The result is the same.

henrythasler · 2016-07-30T19:01:27Z

Same here (Ubuntu 16.04, libboost 1.58). Anyone know a solution/workaround?

edit: I used the egg-file from https://pypi.python.org/pypi/mapnik#downloads and it works w/o any problems.

nurgasemetey · 2016-09-20T12:11:31Z

+1 Same issue (Linux Mint 18, libboost 1.58, mapnik 3.x)

leifole · 2016-09-27T20:19:30Z

Same here on Ubuntu 16.04

fxmzb123 · 2016-09-30T06:09:47Z

Same here on Ubuntu 16.04. Does anyone have a solution for this yet?

rem260 · 2016-10-04T05:23:41Z

Also looking at how we can fix this on Ubuntu 16.04. Rebuilding a machine that had a huge mapnik program and now I can't get it to run.

nurgasemetey · 2016-10-04T07:42:26Z

@rem260 I didn't know how but pycharm automatically installed mapnik when it was not found in my system.

benboughton1 · 2016-10-17T06:24:57Z

Same problem today.

tomse · 2016-10-20T11:03:39Z

+1 for problem
henrythaslers solution seems to work. Import no longer causes errors, but I haven't tried it calling it yet.

benboughton1 · 2016-10-21T03:58:58Z

tomse: It worked for me no worries.

jonatanhjul · 2016-10-26T17:40:30Z

Somebody who has a hint to fix this bug. I am trying to use Python 3, so the pip wheel won't work for me?

cahytinne · 2016-12-30T13:52:55Z

Same problem.

nobohan · 2017-02-07T20:41:44Z

Same problem.

nobohan · 2017-02-09T11:20:28Z

I managed to make the python bindings working (at least import mapnik in python is working). I just deleted the .egg folder in the python-mapnik repository as it is advised in the README.txt of this folder ("However, it is safe to delete this directory."). However, the unit test are not working (python setup.py test) because they rewrite this .egg folder.

talaj · 2017-08-18T15:46:52Z

I hit this while building with MASON_BUILD=true. The python module got linked with system version of boost-python instead of the mason one. The system I'm on uses GLIBCXX_USE_CXX11_ABI=1 so it was not compatible.

I fixed it by export BOOST_PYTHON_LIB=boost_python to pass correct version of boost-python here.

Make sure you are not mixing incompatible libraries during linking. If you are linking dynamically, check that by:

ldd mapnik/_mapnik.so

skasberger · 2017-11-22T13:09:38Z

I have the same problem too. mapnik tests run without an error, but can not import python-mapnik cause of the error reported on top.

ubuntu 16.06
python 2.7.12
mapnik 3.1.0

any news on this?

d3netxer · 2018-01-16T23:59:20Z

I am getting an error too

ghost · 2018-04-22T07:57:47Z

same issue here
ubuntu 16.04
mapnik 3.x compiled exactly by the instructions.
~/mapnik$ make test ---> Works
~/python-mapnik$ python setup.py test --> Does not work

this bug is kinda important isn't it? any ideas?

ghost · 2018-04-22T15:55:03Z

@talaj can you explain a bit more how did you manage to compile this? I don't quite understand how your suggested solution works

did you something like
$export BOOST_PYTHON_LIB=boost_python
$python setup.py install

?

talaj · 2018-04-22T16:41:45Z

@jucajuca I did it as you wrote. There were two boost-python libraries on my system and setup.py has chosen the bad one. I noticed these boost-python versions have different name so I set correct name in BOOST_PYTHON_LIB. I think that setting LD_LIBRARY_PATH should work as well.

Can multiple versions of libraries be also your case?

ghost · 2018-04-23T10:27:29Z

It never worked by compiling it by myself.

Hoewever, I discovered that some dependencies where pulled from a ppa:ubuntugis/ubuntugis-unstable.
That repo has a newer version of mapnik and it broke everything. I removed the repo and:

sudo apt-get clean
sudo apt-get install autoconf apache2-dev libtool libxml2-dev libbz2-dev libgeos-dev libgeos++-dev libproj-dev gdal-bin libgdal1-dev libmapnik-dev mapnik-utils python-mapnik

hope this helps

One interesting issue is with installation process. why I get this log

Installed /usr/local/lib/python3.6/dist-packages/mapnik-3.1.0-py3.6-linux-x86_64.egg Processing dependencies for mapnik==3.1.0 Finished processing dependencies for mapnik==3.1.0
mapnik 3.1.0 ? I have installed last mapnik from source and also I have installed mapnik-python version 3.0.x what is 3.1.0?I have no idea where it was came from

soccerdroid · 2019-03-06T00:35:33Z

Same issue. I installed mapnik from source using python3 (branch master), and the python bindings (using the master branch too).

import mapnik
Traceback (most recent call last):

python3 setup.py install output has a final line:

Which is interesting as noted by @am2222 . The $mapnik-config --version outputs 4.0.0.
Any ideas/hints?

I executed bootstrap.sh, and now mapnik-config --version outputs 3.0.22, but I still get the same error.

am2222 · 2019-03-08T02:31:17Z

@soccerdroid Hi,
I managed to install it using mason_packages=true parameter but it seems if you build mapnik from source it has conflict with mapnik-python.

am2222 · 2019-03-08T02:39:31Z

@soccerdroid As I tried this issue somehow is related into this one
#194
the lboost_python must be the same while compiling python and mapnik-python. I tried but no got no chance.

soccerdroid · 2019-03-19T17:16:17Z

hi @am2222
I don't understand quite well why, but the error disappears if I export PYTHONPATH="/usr/bin:$PYTHONPATH"
I tried adding "/usr/bin" to sys.path, but that doesn't work, possibly because that puts /usr/bin at the end of the list.
Any hints/ideas?

soccerdroid · 2019-03-19T17:31:17Z

Well, I solved the issue by moving /usr/local/lib/python3.6/dist-packages/mapnik-3.1.0-py3.6-linux-x86_64.egg to a different location, not included in PYTHONPATH (same as if I had just deleted the folder). Potentially related to @nobohan 's comment.

am2222 · 2019-03-20T01:39:40Z

@soccerdroid Wow It is great I will try your method. But Does removing 'mapnik-3.1.0-py3.6-linux-x86_64.egg' from that directory ended up with compiling mapnik-python using its mason version of mapnik not the mapnik you have compiled installed on your machine from source?

soccerdroid · 2019-03-20T04:49:17Z

I never built mapnik with mason_packages=True. I don't know if that answers your question. Let us know how did it go for you!

am2222 · 2019-03-20T13:44:48Z

@soccerdroid Yes that was exactly my question, I'll check your solution and will let you know about the results.
Thanks so much
