shared-libraries

Is there a way for a Shared Object file written in C and built on Unix to be called from C# P/Invoke? Or do I need to use Java or something like that? Mono has the ability to integrate with native libraries from within C# built on top of dlopen(3). You just have to use the DllImport statement with the name of the library (i.e. 'libform.so.5'), then wrap the native code and data types with a friendly C# class that takes care of all the low-level stuff. This page has a good overview with lots of information on how to deal with marshaling pointers and other unsafe types. Once you've got your

We've been building a large open source software on a variety of platforms (Linux, Windows, Mac OS X, 32-bit and 64-bit) for several years without troubles. Lately however, the Mac OS X build (64-bit) stopped working correctly and started to crash randomly. It more or less coincided with an update of Mac OS X on our build machine from 10.7 to 10.8.2 (but the compiler toolchain didn't change, it's still llvm-gcc 4.2.1). Our application is made of a couple of dynamic (shared) libraries and many executables using them. One of the shared library overrides the new and delete operators for a variety

When using gcc to build a shared library, it's possible to limit the visibility of the symbols using -fvisibility=hidden . I also just learned you can limit visibility using the version-script option to ld . Now I want to know if it's possible to combine these. Say I have a program with the following: void foobar() {} void say_hello() {} Then I have the version script file with: { global: foobar; } And I compile this with: gcc -fvisibility=hidden -Wl,--version-script=<version-script> test.c -shared -o libtest.so When I run nm on this afterwards, I find that no symbols are exported. Is there

I am using Python 2.7 and trying to use dateutil as follows: from dateutil import parser as _date_parser However, I get the following error: Traceback (most recent call last): File "<pyshell#17>", line 1, in <module> from dateutil import parser as _date_parser File "C:\Python27\Lib\dateutil\parser.py", line 24, in <module> from six import text_type, binary_type, integer_types ImportError: No module named six Could you please let me know what is the six module for and how to get it installed in a Windows 7 machine? You need to install this https://pypi.python.org/pypi/six If you still don't

We have been converting our Java and .NET API library to C++, and are trying to figure out what is the best way to distribute a compiled version to other developers to use with their custom applications. Should it be a static library or dynamic library? We need to create for both Win32 and Win64 (and I suppose both a Debug and Release version of each target OS). Given all the frustration I've encountered trying to make sure all referenced libraries are matched (/MT versus /MD), I'm wondering if there is a decision to make here which will simplify it for other developers. When I run dumpbin
