C++ extention

I have a python extention implemented in C/C++
- the extention itself is internally implemented in C++, but
the interface is pure C, so that it can easily be called from
a python C-wrapper.

The extention is compiled with distutils, and this has worked
well in both Windows and Linux environments.

Now, however, I get an

undefined symbol _ZTVN10__cxxabi v117__class_typ e_infoE

when I try to import the extention on Linux (only linux).

I think this has happened after gcc was upgraded to gcc 3.2.2

Has anyone seen this? What could be the problem?

I don't know why this tedious problem has cropped up with the new
gcc - but anyway I have fixed it now by "manually" forcing it to
choose g++ as the linker - on linux platforms.
It would be nice if distutils could take care of this itself...

I am embedding python in my C++ application. I am using Python *2.3.2* with a C++ extention DLL in multi-threaded environment. I am using SWIG-1.3.19 to generate C++ to Python interface. Now to explain it in details, 1. Python initialization and finalization is done in the *main* thread. 2. For each new thread I create a separate sub-interpreter . 3. Using PyRun_String("import myModule"...) before execution of python

I am currently writing an extention module that needs to recieve a list of characters that might vary in size from 0 to 8. This is written as a list of characters rather than a string because it's easier to manipulate. However, when I pass this list of characters into the extention module, it keeps giving errors. Is there a way to do one of the following? A. Change a list of chars to a single string or B. Read a list of chars in an...

I'm do meore and more with extention methods, totally cool. They are making life much easier for IU developers. I'm trying to add a return type of struct to a asp.net DropDownList of type struct. The idea is that if the conversion to say Int32 failed and a default value was used i can also return a Pass/Fail bool, int code to let the developer know that it failed or the reason for the failure. Where should the struse be defined for the...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
