The operator= stuff is usually innocuous. The compiler died because it couldn't find 'vector', which is reasonable, since it thought it was compiling a C file.
Probably because you swigged the file without the magic "-c++" option -- I'm not sure how distutils passes arguments to swig, but if you do it from the command line, you'll do something like swig -c++ -python -I<path to python> <file> and it will generate a .cpp file and a .py file, which will (hopefully) compile. I'd focus on doing it manually, then getting distutils to work properly. -----Original Message----- From: Hyuga [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 27, 2008 10:01 AM To: python-list@python.org Subject: Re: first time use of swig, python and c++ .. it's a mess ... please advice On Feb 26, 3:38 pm, Eric von Horst <[EMAIL PROTECTED]> wrote: > Hi, > > we have a third-party product that has a C++ api on HP-UX. > > I would like be able to use the API in Python (as I remember Python is > good at doing this). > > I have no experience with this so I Googled and tried to find some > info on what I had to do. > > So, I installed Python 2.4.4 and Swig 1.3.33 > > The header file to the library is '/opt/OV/include/opcsvcapi.h'. > > I created a SWIG file with the following content: > " > %module opcsvcapi > %{ > /* Includes the header in the wrapper code */ > #include "/opt/OV/include/opcsvcapi.h" > %} > > /* Parse the header file to generate wrappers */ > %include "/opt/OV/include/opcsvcapi.h" > " > Then I ran the cmd: > # swig -c++ -python opcsvcapi.i > with output: > " > /opt/OV/include/opcsvcapi.h:41: Warning(362): operator= ignored > /opt/OV/include/opcsvcapi.h:46: Warning(503): Can't wrap 'operator > Type' unless renamed to a valid identifier. > " > > The result are two files: > opcsvcapi.py > opcsvcapi_wrap.cxx > > I created a 'setup.py' file with the following content: > " > import distutils > from distutils.core import setup, Extension > > setup(name = "opcsvcapi", > version = "1.0", > ext_modules = [Extension("_opcsvcapi", > ["opcsvcapi.i","opcsvcapi.cxx"])]) > " > > Then I run: python setup.py build > > This results in an extra file: > opcsvcapi_wrap.c and a 'build' directory > > and the following errors: > " > running build > running build_ext > building '_opcsvcapi' extension > swigging opcsvcapi.i to opcsvcapi_wrap.c swig -python -o > opcsvcapi_wrap.c opcsvcapi.i creating build creating > build/temp.hp-ux-B.11.11-9000-800-2.4 > gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict- > prototypes -fPIC -I/usr/local/include/python2.4 -c opcsvcapi_wrap.c -o > build/temp.hp-ux-B.11.11-9000-800-2.4/opcsvcapi_wrap.o > In file included from /usr/local/include/python2.4/Python.h:8, > from opcsvcapi_wrap.c:118: > /usr/local/include/python2.4/pyconfig.h:851:1: warning: > "_POSIX_C_SOURCE" redefined > <command line>:1:1: warning: this is the location of the previous > definition In file included from opcsvcapi_wrap.c:2490: > /opt/OV/include/opcsvcapi.h:12:18: error: vector: No such file or > directory In file included from opcsvcapi_wrap.c:2490: > /opt/OV/include/opcsvcapi.h:15: error: expected '=', ',', ';', 'asm' > or '__attribute__' before 'SvcAPI' > opcsvcapi_wrap.c: In function 'Swig_var_SvcAPI_set': > opcsvcapi_wrap.c:2505: error: 'SvcAPI' undeclared (first use in this > function) > opcsvcapi_wrap.c:2505: error: (Each undeclared identifier is reported > only once > opcsvcapi_wrap.c:2505: error: for each function it appears in.) > opcsvcapi_wrap.c:2505: error: 'namespace' undeclared (first use in > this function) > opcsvcapi_wrap.c:2505: error: expected expression before ')' token > opcsvcapi_wrap.c: In function 'init_opcsvcapi': > opcsvcapi_wrap.c:3064: error: 'Swig_var_SvcAPI_get' undeclared (first > use in this function) > error: command 'gcc' failed with exit status 1 " > > and that's it. > > Any idea what I am doing wrong? > > Any help much appreciated > > Kris Well, the errors you got from the compiler are just confusing to me, but I suspect it goes back to the warning you got from SWIG. Some class in there is overriding the = operator, but since that can't be done in Python, you need to give it some special instructions on how to handle that. For example, if you have Foo::operator=, in your SWIG header include a line like: %rename(assign) Foo::operator= Then in the Python module, the Foo class will have an assign method.
