Question about items changing in .cproject file

stevenh
Guru 20045 points
Other Parts Discussed in Thread: CCSTUDIO

Hello,

My .cproject file has changed.  I included a part of the old and new .cproject files below.  

The items that have changed are related to the compiler tools.  Both the old and new .cproject files list the codegen version as 6.2.11, so why are the version numbers of the other items changing, i.e. .C2000_6.2.compilerID.UNIFIED_MEMORY.654325883 changes to .C2000_6.2.compilerID.UNIFIED_MEMORY.1314806860?

    Everything I know about the .cproject file is here.  Which is to say, I don't know very much.  I'm pretty sure this file is controlled by the CDT extension to Eclipse.  That extension was not contributed by TI.  So I don't know that anyone at TI knows the contents of this file to that level of detail.

    Do you know what you did that caused this change to occur?

    Thanks and regards,

    Hello,

    The "New" part I posted did show the compiler version, so I am posting it again with that part.

    I just noticed that the old .cproject file was based on a debug build and the new one is based on a release build.  Could that be causing the issue?

    Hello George,

    Changing the Configuration to "Debug" did not change the .cproject file significantly.

    Yes different build configurations could have different metadata.

    There really isn't any detailed specs about  this project file and it is meant to be treated by the user as an opaque metadata file.  Of course, if there is a specific scenario where the file changes in an unexpected manner causing the build to break, for example, then we could treat those individual cases as bugs.

    Hello AartiG,

    Thanks for reply.

    My concern is that a change in version number of any of the build items (i.e. com.ti.ccstudio.buildDefinitions.C2000_6.2.compilerID.OPT_FOR_SPEED.102016672 , com.ti.ccstudio.buildDefinitions.C2000_6.2.compilerID.UNIFIED_MEMORY.1758079454 and etct) will change the executable in an unexpected way.

    I may think that I am only making a simple change to my code and that I only have to test that simple change.  However, that's may not be true if the version changes to one of the above items.

    What does changes to the version of the above items mean?

    He Stephen,  

    The random number suffixes, that you're referring to, are not versions.  They're just meant to ensure that each build-flag setting has a unique ID within the scope of the .cproject file and its super-class hierarchy.  Any changes in these IDs do not directly cause changes in the executable, because these ID changes do not necessarily mean that the generated build-flags also change.  

    A change in the executable can be more directly caused by changes in the actual build commands that are executed during the project build.  If you are concerned about unexpected changes to the executable, you could copy the console output of the build, source-control that in a plain text file, and track any changes in it as you make small changes to the project and build.  This may not work well in a team environment though, because the build-output contains machine-specific absolute paths...

    Hello Baltasar,

    Thanks.

    Is any place I can go to learn more about the .cproject file settings?
