Never mind, those single quotes looked like one double quote on my screen....

Does the name of the module defined in your BOOST_PYTHON_MODULE section match
the name of the .so file (assuming you are using Linux)? That's usually the
error I get when I have a name mismatch.
Also, I haven't really used scons, but shouldn't this:
env.SharedLibrary(target='cylucene', source=FILES, SHLIBPREFIX='')
be:
env.SharedLibrary(target='cylucene', source=FILES, SHLIBPREFIX=''") ?

Subject: [C++-sig] Building with Scons
Hello,
I am trying to build a python extension with scons but the resulting
library cannot be loaded:
ImportError: dynamic module does not define init function (initcylucene)
I am using the following SConstruct file:
FILES = ['typeconversion.cpp', 'document.cpp', 'search.cpp', 'queryparser.cpp',
'analysis.cpp', 'index.cpp', 'store.cpp', 'util.cpp']
def python_tool(env):
pybase = 'python%s' % sys.version[0:3]
env.Append(CPPPATH=[os.path.join(sys.prefix, 'include', pybase)],
LIBPATH=[os.path.join(sys.prefix, 'lib', pybase, 'config')],
LIBS=['lib%s' % pybase])
if env['PLATFORM'] not in ['cygwin', 'win32']:
env.Append(LIBS=['util'])
def boost_python_tool(env):
env.Append(CPPDEFINES=['BOOST_PYTHON_DYNAMIC_LIB',
'BOOST_PYTHON_DYNAMIC_MODULE'],
CPPPATH=['$boostIncludes'], # boostIncludes is a PathOption
LIBS=['boost_python'])
def clucene_tool(env):
env.Append(CPPPATH=['/usr/local/lib/CLucene/',
'/usr/local/lib/'],
LIBS=['clucene'])
import os
env = Environment(ENV=os.environ, tools=['default', python_tool,
boost_python_tool, clucene_tool])
env.SharedLibrary(target='cylucene', source=FILES, SHLIBPREFIX='')
Previously I was using the following Makefile, which worked but was
statically linked:
SHELL = /bin/bash
SRC = ./src/
BUILD = ./build/
INCLUDES = -I/usr/include/python2.6/ -I/usr/local/lib/ -I/usr/local/lib/CLucene/
LIBS = -lboost_python -lpython2.6 -lclucene
CFLAGS = -shared -fPIC -g -pedantic -Wall -Wextra
OBJECTS = document.o search.o queryparser.o analysis.o index.o store.o util.o
LOBJECTS = $(BUILD)typeconversion.o $(BUILD)document.o
$(BUILD)search.o $(BUILD)queryparser.o $(BUILD)analysis.o
$(BUILD)index.o $(BUILD)store.o $(BUILD)util.o
all: cylucene
cylucene: $(OBJECTS)
mkdir -p $(BUILD) && cp $(SRC)initfile.py $(BUILD)__init__.py
$(CC) $(SRC)cylucene.cpp $(LOBJECTS) $(INCLUDES) $(LIBS) $(CFLAGS) -o
$(BUILD)cylucene.so
document.o: typeconversion.o
mkdir -p $(BUILD)
$(CC) $(SRC)document.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o
$(BUILD)document.o
queryparser.o: typeconversion.o
mkdir -p $(BUILD)
$(CC) $(SRC)queryparser.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o
$(BUILD)queryparser.o
analysis.o:
mkdir -p $(BUILD)
$(CC) $(SRC)analysis.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o
$(BUILD)analysis.o
search.o:
mkdir -p $(BUILD)
$(CC) $(SRC)search.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o $(BUILD)search.o
index.o:
mkdir -p $(BUILD)
$(CC) $(SRC)index.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o $(BUILD)index.o
store.o:
mkdir -p $(BUILD)
$(CC) $(SRC)store.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o $(BUILD)store.o
util.o:
mkdir -p $(BUILD)
$(CC) $(SRC)util.cpp $(INCLUDES) $(LIBS) $(CFLAGS) -o $(BUILD)util.o
typeconversion.o:
mkdir -p $(BUILD)
$(CC) $(SRC)typeconversion.cpp $(CFLAGS) -o $(BUILD)typeconversion.o
clean:
rm -Rf build/
Does anyone have experience working with scons and boost::python? Can
anyone help?
Thanks in advance!
