Is there a Source Insight alternative?
Solution 1:
Code::Blocks might be an option.
Code::Blocks is a free C++ IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable.
An IDE with all the features a developer need, having a consistent look, feel and operation across platforms.
Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin. For instance, compiling and debugging functionality is already provided by plugins!
Runs on windows too
I'll let someone else post about codelite and widestudio so you can pick one
Solution 2:
I think what you want is a Source-Navigator
if you still don't like this, you can wine your source insight.
