RE: Compilation with multiple jobs fails

[Ramya S Ganesh (RBEI/ETC5)]

Hello,
            We made use of the below command for starting parallel build 
process with an intent to solve the "Waiting for unfinished jobs" issue.
            make --output-sync=recurse -j $parallel_process -f

*        We used --output-sync=recurse to synchronize the parallel tasks.

*        -j $parallel_process( where parallel_process=$NUMBER_OF_PROCESSORS-1) 
it automatically detects the cores in the system.

But still we face the issue, Can you suggest a solution for the problem?
Are the options we are using the right ones or are there any other alternatives.


Best regards

It looks like your GUI covered up the actual error in the line above the "Error 
code 1."

The "Waiting for unfinished jobs" is just telling you that other parallel tasks 
are still executing.

Hello,

           We have a build tool that uses make scripts with GHS compiler. I had 
attached the GUI of the tool.

Kindly find below the steps in the build process of our tool.

1)         Basic file configurations like setting paths and updation of batch 
folder.

2)         Deletion of all the object files generated in previous build.

3)         Creation of source files(.c) for measurement variables and constants 
in the project.

4)         Conversion of  all the compiler and linker flags from the project 
folder into.ccf,.lcf in the workspace.

5)         Creation of a .c file with user, project, time of build details.

6)         Compilation of .c files in the project, along with the c files 
generated in step 2 and 4 by making use of compiler and linker flags in step3 
and finally generation of library files.

7)         Linking all library files to generate .hex, .mot and .elf files.

8)         Creation of .a2l files for the measurement variables and constants 
in the project.

9)         Merging all the .a2l files.

10)       Creation of delivery software.

11)       Container generation.



We made use of parallelism along with synchronization for starting the build 
process and got the error message I had attached .

[cid:image004.png@01D2E10C.C1F65850]



Kindly find below the command used for parallel build process.

make --output-sync=recurse -j $parallel_process -f



Just for information - the error message occurred on different PCs not always, 
but with high probability.



Could you please have a look into it a suggest a reason for the problem.



Thank you,
Best regards
