Speeding up build times

[IBNobody]

What can I do to speed up build and debug times on my programs? Right now, the program I'm working on takes 45ish seconds to complete the build and execute steps.

I'm using a workspace with multiple projects present at once. Only one project gets compiled. I've noticed, though, that the generated build.ini lists a bunch of include files in the [Included Headers] section. (123 to be exact.) Could this be slowing down the build steps?

Hello IBNobody,

Do you get the same slow build time when you create a release executable?  Also, you mentioned that it takes 45 seconds to build and execute.  Does this mean that it takes that long for CVI to display your user interface?  In the build.ini file, you should only see include file references for those files/libraries you include at the top of your source file.  Do you see any extraneous entries, or those that refer to the other projects in your workspace?

Thanks.

45 seconds was incorrect. It just seemed like a long time.

Creating a release executable and running it takes 10 seconds.

Creating a debuggable version takes 15 seconds for the program to reach the first statement in MAIN.

Yes. See below.

My project doesn't even use "c:\Shark_Software/30004-1 SK3/_Engine_Setup.h". It uses its own "_Engine_Setup.h" file that is located in the current active project.

Hello IBNobody,

What I would suggest is for you to create a new workspace and project.  The add all the necessary files to the new project and workspace.  Then recompile the project and see if the build and execution times improve and also if the reference to the Shark_Software header files go away.

Thanks.

Is there any other way to get CVI to not include the header files? I have roughly 30 individual projects, and it would make things difficult to have 30 individual workspaces for each project.

Hello IBNobody,

Say for instance, we have project 1 and project 2 included in our workspace.  I do see the behavior that the build ini file for project 1 will have references to the include files in both project 1 and project 2, and vice versa.  For test purposes, If you add your project to a new workspace without the other projects, then compile and run your project in this new workspace, do you see an increase in build time?

Thanks.

Wendy,

I figured out why my build times were so slow for these projects. I'm using DAQmx, and the libraries have a negative speed impact on compile/execution times. (I'm running everything on an old 800 MHz monster.)
