Calling C# from C++
by silent wind on Mar.30, 2012, under C Sharp, C++, Windows
Most of the post on the internet about interoperability is the other way around (Calling C++ from C#) since C# is apparently the superior language in terms of developer friendliness. But a part of research work is to make weird combinations of system work regardless of the reason.
I succeeded in doing just that thank to this Visual C++ example (documentation is available in part 1 of the tutorial).
One thing to add is, I needed a tool to export .NET 4.0 to .tlb files so I can use the same assemblies in C++ (pure C++ and not C++.NET). The tool is called tlbgen, and the syntax is quite simple:
tlbgen System.Net.dll
Installing subversion support for Eclipse on Linux

You have two choice: subversive (Belongs to the Eclipse project) or subclipse (hosted on tigris.org).
Even though Subversive is the more ‘official’ option, I find it prohibitively confusing to install. You have to go to an external site (polarion) and download a bunch of stuff nobody told you what. It took me 2 hours fiddling back and forth between Eclipse site and Polarion site only to install the wrong stuff. Highly not recommended! Agrh!
I have a better start with subclipse. The only URL from their site worked perfectly with eclipse’s ‘install new software’ dialog. Better still, you don’t really need to install JavaHL (which is also ridiculously hard to install), you can use the SVNKit package in the same repository and everything will work.
To install subclipse, go here
For those of you who prefer JavaHL, here is how to install JavaHL on Fedora 16. JavaHL is another middle layer required between any Eclipse plugin and SVN (I don’t know why things are so complicated when it come to designing on Linux). Most of the sites on the internet recommends you to install that by
sudo apt-get install libsvn-java
But there is no such package on Fedora, so I tried to use add/remove software and searched for various part of the name. I finally found it when searching for ‘JavaHL’, the correct package name is
subversion-javahl
Documentation and tutorial and another thing the Linux community didn’t do well!
