Project Explorer fails to display one particular source file

Roy Jackson
Intellectual 820 points

I have CCS Version: 6.0.1.00040 and it has been working fine with a medium-large project. Today, I used my code generator tool (EA) to add a new cpp file and hpp file to the project like I've done many times before but only the hpp file appeared in the Project Explorer (in the includes folder, as normal) The cpp file is visible in Windows Explorer, but not in Project Explorer.

That's odd, but this is weirder : if I rename the file (add or change one letter) it appears in Project Explorer in the source folder, where it should be. Pretty much any name seems to work. But if it's called MessageDecoder_t.cpp it doesn't display.  Is this a forbidden filename?

    Hi Roy,
    Nothing is wrong with that name. I tried it myself and it shows up in the Project Explorer view. I tried copying it to the project folder and also linking it. If have a file of some other name in the Project Explorer view and then rename it to 'MessageDecoder_t.cpp' using the rename option by right-clicking on the file in the Project Explorer view, does the file then disappear from the view?

    Thanks

    Interesting.  If I rename another file to MessageDecoder_t.cpp it DOES disappear, and reappears when the name is changed back. However, when I do that in a different source folder it DOESN'T disappear. Only one of my source folders behaves oddly!  It doesn't make any difference whether the rename operation is carried out inside Project Explorer, or outside CCS.

    Well, provided the problem doesn't get any worse, I can live with it. It does make me feel concerned though.

    Are each of the source folders in separate CCS projects, or are they part of the same CCS project?


    For the CCS project which contains the source folder which behaves oddly, can you check the project properties to make sure there is no resource filter to hide files? E.g. in the following example I applied a filter to "hide" main.c from a project:

    If a resource filter doesn't explain the problem, can you post the .cproject, .project and .ccsproject files from the CCS project for the source folder which behaves oddly, to see if there is some other project attribute(s) which are causing the problem?

    Thanks. Both folders are in the same project, and I have no resource filters in that project - the window is empty.

    However, looking in the .cproject file turns up something interesting:

    <sourceEntries>
    <entry excluding="Vcast|Vcast/mingw/CCAST_.CFG|Vcast/CCAST_.CFG|CppLibrary/Includes|NonaSource" flags="VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name=""/>
    <entry excluding="MessageDecoder_t.cpp|NonRecursiveFilter_t.cpp|MorphFilterTop_t.cpp|MorphFilterBot_t.cpp|MedianFilter_t.cpp|Maths.cpp|GpioTest.cpp|UppTest3.c|includes" flags="VALUE_WORKSPACE_PATH|RESOLVED" kind="sourcePath" name="NonaSource"/>
    </sourceEntries>

    Removing MessageDecoder_t.cpp from that exclude list fixes the problem.

    It leaves me wondering how the exclude list came to exist and how MessageDecoder came to be in it. I suppose I'll never know exactly, but most of the other files in that list were at one time in the problematic folder (NonaSource) before they were removed to a library folder.

    Thanks again for your help. I'd be grateful if you could confirm that the best resolution is to remove MessageDecoder_t.cpp from the list. Or would it be better to remove the entire list?

    Thanks

    Roy - it looks like somehow those files/folders were specified to be excluded from the project and the view filter for the Project Explorer had the below option enabled:

    That would include filtering out all excluded folders/files from the view.


    The question is how did this happen if you didn't explicitly do this? Are you using some Eclipse plug-in (like VectorCAST) that might have mucked around with your settings automatically?


    Thanks

    I don't know, Ki, it's a mystery.  I haven't used that dialog to set up any filters, and Non-C elements isn't checked

    Someone setup Vector Cast for me a few months ago, but I don't use it. And I can't imagine why VCast would finger one particular file.

    So, is there any reason why I shouldn't remove the whole of the exclude list using a text editor? None that I can see!

    What I have discovered is that if you R-click on a file in Project explorer and select 'Exclude from Build' that file is added to this exclude list in .cproject.  The file doesn't completely disappear though - it goes grey and moves to the bottom of the list where it's a little harder to see. That's probably how it happened.

    Thanks to you both, especially Chester for the hot tip about looking in .cproject.
