RE: Compilation with multiple jobs fails

Again, you need to show the actual error, the PNG file you sent covered 
the actual error.

You may want to send the data as text.

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.

                                                      [
cid:image003.png@01D2E10C.C1F65850]

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
