slow XC16 compile with blockset v.3.46.03

Hi,
 
I'm experiencing slow compile times when building the MCHP examples.  The model I am testing currently is Explorer1632_LCD.  It seems to build the Simulink model in good time, but when it begins to compile in XC16, it is very slow.  It seems to take about 1 second per line of text output to the diagnostic window, even when displaying stuff that should be very fast (like "printing" the compile summary at the end).
 
The total build time is around 4 minutes.
 
Samsung laptop
Gen 2 Core i7 quad core
12 GB ram
R2019b
XC16 v.1.50 (in "free" mode [max optimization=1])
blockset v.3.46.03
ICD3 connected, "flash after build" off
 
Any ideas, please?
 
Thanks,
Justin

    Hi Justin,
     
    For completness, below is the sum-up of our email discussion:
    Compilation process is usually faster than the code generation when the html report is activated with link to model etc... 
     
    The generated .X folder contains a <modelname>.bat file which allows to compile the .c file from a dos command.
    On your setup,
    - compiling from dos was fast.
    - compiling from the matlab command prompt using !<modelname>.bat command was fast either.
     
    - compiling with the diagnostic windows closed did not solved the speed issue (message are still beeing captured in the diagnostic windows anyway).
    It seems the compiler msg outputs captured in the diagnostic windows mechanism is the bottleneck.
     
    Could you try unchecking the multithread compilation in the compiler block ? Using only one CPU core for compilation might keep others core free to handle Maltab & Java underneath.

    Thanks for adding the comprehensive history of this issue, Lubin.
     
    I had actually tried that before (disabling multithread compilation) but I tried it again, this time without the diagnostics window open.  It took about 15 seconds longer than with multithread enabled, so it doesn't seem to help.
     
    Is there anyway to disable the text output to the diag window completely (just as a test to see if it speeds it up)?

    Hi Justin,
     
    Replace the attached file in the mchp folder. (for v3.46.0x ONLY)
    Compilation output are redirected to a file "out.txt" in the .X folder.
     
    Compilation will always be notified as fail in the diagnostic windows even if it is ok.
     
    Check the out.txt file or check the timestamp of the binary file to make sure compilation is ok, and program the file using the Microchip->Flash from the  Simulink menu bar.
    Is compilation time any better?

    Hi Lubin,
     
    Thanks for the update. Yes, that made a major difference!
     
    Build + compile times went from about ~3:40 to:
     
    Single thread: 1:06
    Multi thread: 1:17
     
    The weird thing is, when running in multi thread mode, it seems to produce an error that is not seen in single thread mode. Please see diag output below.
     
    Also, I tried to save the model with multithread and reopen it (to see if that made any difference in the compile times), but it would always open with single thread (even if it were saved in multi thread before).
     
    Single thread diag window output:

    Hi Lubin,
     
    Would it be possible to add a switch to "send compile output to out.txt" or something in the upcoming blockset release?  Your solution in post #4 seems to have solved the compile time issue.
     
    Also, do you have any ideas as to why multi-thread produces errors?  I'd be happy to try anything you can think of.
