Visual Studio need to rebuild solution for every change

问题

I am currently working on a game engine in c++. As I have progressed further into the project, I have noticed that the resulting executable often does not reflect the latest code changes. But completely cleaning the solution and rebuilding it, fixes the problem. Unfortunately a complete rebuild is not a viable option for a larger code base anymore.

I have already checked different solutions on stackoverflow:

• I have checked that my "Build and Run" setting is set to "Always build"
• The Configuration Manager is also set to "Build"

Additional information:

• It is an OpenGL project with GLFW and glad in c++
• I use Visual Studio Community 2017 Version 15.2

This is a really annoying issue that causes a lot of productivity loss, since I have to completely rebuild the entire solution every time I want to see a change. I would be grateful for any input. Please ask if more information is required.

I don't know if this is of any relevance, but this is what I get when making a small change to TestScene.cpp and rerunning the code:

UPDATE

Here is an in depth explanation of the issue:

1. I have a class that allows to rotate an object TransformerScript.cpp
2. I have set the rotation speed to 1.
3. The object rotates as expected.

4. Now I change the speed float value from 1 to 0.
5. I press run (Local Windows Debugger)
6. This is the output log:

========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

7. The compiled executable starts
8. The result is the same figure rotating at the same speed.
9. Expected behavior: No rotation, since the float was set to 0.
10. I am forced to "clean solution" and "Rebuild solution"
11. This takes about 1 to 2 minutes on my laptop
12. VS finishes rebuilding the new solution
13. I press run (Local Windows Debugger)
14. The Object is not moving. (This is as expected)

Alternative approach

1. Set break point at the position of the speed float value
2. I press run (Local Windows Debugger)
3. Sometimes (90% of the cases) an error Prompt pops up. Other times (10% of the cases) everything works as expected

4. I press ok
5. The compiled executable starts
6. The result is the same figure rotating at the same speed.
7. Expected behavior: No rotation, since the float was set to 0.
8. The break point is not triggered!

回答1:

I had the same issue with one of my C# projects and solved it like this:

1. Go to Solution > Properties
2. Check Configuration Properties > Configuration
3. In my case, the Build flag was not checked for one Project in the Solution

If the changes are in a header file you will need to full rebuild for the changes to be reflected I think.
