Problem while compiling with a customized header

TURJASU PYNE1
Expert 1310 points
Other Parts Discussed in Thread: TM4C123GH6PM

Dear all,

 I was trying to configure and initialize ILI9341 display controller with 240 X 320 Pixels of Color TFT display using the TM4C123 and the program has worked perfect. However, after checking a sample prototype software, I tried to create individual header called LCD2_2SPI.h and an associated c file named: LCD2_2SPI.c . After doing this, I have included the header file in the main program given below:

Now the problem is that, when the functions TivaInit(); Lcd_Init(); LCD_Clear(BLACK); (highlighted below in light blue) was directly defined inside this main.c file, there were no compilation error. However, when I created a header and shifted the definitions and declared the functions in the header and defined them in LCD2_2SPI.c , there are errors coming (compilation errors) saying: #10234-D unresolved symbols remain in these three functions. The Problems window is screenshot below:

 

 

Please help as to what might be going wrong. I have tried a lot checking everything. I am using TivaWare_C_Series-2.1.1.71 and the configurations in CCS project and libraries are fine. The project runs successfully when the functions are defined in main.c and declared in main.c But errors show up when moved to the header LCD2_2SPI.h and an associated c file named: LCD2_2SPI.c

    I noted this post hours earlier - hoped that someone familiar w/this vendor's (singular) IDE would respond.

    I checked all 3 of the error creating functions - iirc I could not find the closing brace for the last one.  (last appearing in your code - yet I don't believe that's the cause of your error.)

    Vendor's compiler reports (only) those first 3 "now external" functions are flawed - yet I wonder about "all others."    And I note that those failing are the very first one's called - after you set system clock.  Would it not prove useful to "switch those 3 - error causing external functions" with 3 other external ones?   (i.e. those not flagged as, "in error")     Such would reveal that your compiler can handle - at least some - of your added, external functions.

    In addition - might you greatly shorten at least one of those failing external functions - and repeat your test?   I'm aware that the program cannot (then) perform to your liking - but such signals "if" the issue is within the external function itself or requires some added file notification or dependency.

    Each of those failing functions appear reasonably large - perhaps you must notify other files w/in your program of the presence of (both) added SPI functions.  (.c & .h)

    Hi Turjasu,

    Also in addition to CB1 notes please check for remaining or typo existing in the exports moved and clean the project before compile. Past had a typo in an moved export cause the same kind of errors. Took long time to see but one day the exported variable name was noticed very odd. Ended up being a label of an exported struct classified name in the resource was incorrectly being called by another name in the export.

    Greatly shortening each of the errant functions - as far earlier suggested - eliminates the "search for typo."

    It's hard to know where to start.

    The header file does not belong in driverlib
    The initializations do not belong in the header
    You are missing a lot of brackets in your defines
    Indentation is missing but that may be because you didn't use the code paste facility
    The protective header define could be better named. The chance of the current definition colliding is high
    What every one else complained about

    Finally the error you are complaining about is from the link and locate step. It suggests you haven't linked and/or compiled the file containing the functions

    Thanks cb1 for your reply.

    I understand that the last function has no closing }, but i just forgot to copy paste it here. otherwise it is there in the actual code.

    Now coming to the point that the failing functions are the ones which are called initially under main.c . This is true! That is why i tried blocking all of them and created a simple function called useless as given below:

    void useless(void)

    {

    }

    And tried calling this in main.c and the same error appeared. Proving it that the compiler was totally unable to handle any external functions.

    Also I tried calling other external functions from other libraries previously defined by TI in its tivaware and they worked fine. But in the same header and corresponding .c file when i am defining a small function and calling it in main.c, It failed to compile and generated the same error!

    I do not understand why this is happening!

    And finally I created a blank project called TEST and included a new header called test_header.h and defined the function

    extern void useless(void)

    and defined it in test_header.c :

    void useless(void)

    {

    }

    and called it in main.c

    And the Error still happened. This proves it is independant of the function, the compiler has some issues.

    I am using Windows 8.1 PRO, is it someway related to the OS? I might be wrong, but still...

    No, it does not.

    There are alternative and far more likely explanations considering that others are successfully compiling multiple source projects. I thin kthe most likely is that you are simply specifying your build incorrectly.

    You can make a simple check of whether you are at least compiling test_header.c Add a line like

    never_declared = 35qr;

    to the useless function.

    If this does not produce a compiler error, then you are not compiling the test_header.c module.

    Hi,

    Both Robert and Amit told you, but not sufficiently imperative: do not place your files in driverlib folder! place them in your project root folder, even make your "drivers" folder into your project root - see Tiva examples. Otherwise you need to recompile driverlib - but this method is prone to further problems - if you change the driverlib version, your files will be lost, even forever.

    Second, when declaring/writing your own files, do not use double underscore prefix, use a single underscore postfix, aka instead __LCD2_H use LCD2_H_. The double underscore prefix is to be used by compiler internal names; do not interfere with them!

    Hi,

    That log appears truncated and please confirm you do clean this project after moving the code from (main.c) into you new file?

    Clean project close CCS & reopen, rebuild the index, Check for and resolve missing includes: right click on project folder for all tools.

    The problem seems to be in (main.c) judging from truncated log. My find has been the very first warning or error tends to be a pointer to the problem. For instance having an include (main.h) in the new header file pointing to code left behind referenced by exported variable or function in the new header file sometimes makes the compiler throw many errors, refuse to continue linker is never invoked.

    Hello Turjasu,

    My apologies but I am sorry to say that I have never seen such a code which is highly unstructured. I would strongly advise to follow a good coding structure to make sure that variables and functions are well defined and exported.

    Regards

    I do agree with you. But it was created in a haste by my colleague and then handed over to me. I fully accept your observation.
    The header and the c file both are not done by me and is just a result of doing things in haste. All my codes are much better and commented as well as structured.

    Hello Turjasu

    I would suggest re-doing it since the functions may be correct but syntax structures are not correct.

    But the problem also persists even if I am making a blank program as I said before. And the c file is not getting compiled at all.

    > But the problem also persists even if I am making a blank program as I said before. And the c file is not getting compiled at all.

    The program is actually trying to compile, "check debug folder (main.obj) is being renewed on the next compile after you cleaned the project. Notice the debug folder is emptied during clean. Compiler stops at main.obj and is not even getting to linking due to encountered export errors during compile.

    The tough part is locating where the exports are going amuck. Like I pointed out earlier if you have even one export in the new file pointing to a function in (main.h) that was moved from (main.c) into your new C file the compiler can not locate the symbols. An improper name given for an exported variable can also cause the same symbol errors.

    Hello Turjasu

    Attached is a simple hello program which uses a function in file clockfunc.c and clockfunc.h which can be called in main.c. You can use this as a reference.

    hello.zip

    Hi Amit,

    Bravo - believe this type/style example (as you've just furnished) properly "models" user's issue/requirement...

    Mefears that "own project" issues may remain - thus new (further) complications may lurk...

    Hello cb1,

    I wanted to establish a baseline for any further complications.

    Dear Sir,

    Thanks a lot for your help. Now I have developed the headers and the entire project is structured as it should be and is working fine. Figured out the problem which was relating to the creation / consolidation of the declared array as well as the functions in a single header. Moreover, as per your hello example, I have restructured the header inclusions in the c file and not under main. Also I have segregated the font header as a separate header for the project so that the functions related to the LCD were in separate header, which helped remove the compilation problem.
    I will upload the entire project shortly along with the sampled header so that others facing this issue may get it solved.
    Thanks to everyone who has helped me.

    Hello Turjasu

    You may still want to keep your project to yourself unless as it may be your organization's propitiatory information.

    The template in my post may be useful to others.

    Thanks sir. I will share what can be shareable. Apart from your template, it has a good way of initializing ILI9341 based lcd that is not available in forum and might be helpful

    Hmm, well that would be a good pointer to folks doing or planning to do the same.
