Looking for example of "Post-build steps"
Pavel_47:
Hello,
I want to integrate arm-elf-objdump tool in Code::Blocks, that disassemble an object file.
I want it to runs immediately after build is terminated.
So I considered that "Post-build steps" option is the best location to integrate arm-elf-objdump into processing flow.
But unfortunately I didn't find any document that would help me to resolve the problem.
Anyway I've just tried command-line case for arm-elf-objdump (this way this command is executed from command line).
Without surprises it didn't work ... none disassembly file was generated.
Certainly, the Post-build step command have a particular syntax that probably uses placeholders for input/output and flags.
Is someone aware of such kind of things ?
Thanks.

Small correction: the correct name of the command is arm-none-eabi-objdump, the name I used in previous message is from old version of "GNU Tools ARM Embedded"

I'm not sure, if output redirection works directly from the post-build steps.
You probably can call objdump within it's own cmd instance like:
--- Code: ---cmd /C "arm-elf-objdump ... "
--- End code ---
but then you have to set the paths to the compiler executable and the object files. You can use Code::Blocks variables for this (cf. http://wiki.codeblocks.org/index.php/Variable_expansion).
Alternatively, you can put the whole command in a batch file and start it from the post-build steps (again, with the full path to the compiler and object files).
The result of the post-build step execution is shown in the Build Log. Just check the messages there if anything doesn't work as expected.

Thanks Christobal,
I've tried your suggestion. For the moment it doesn't work.
But I think it's a right way to explore.
At least I've found a conformation of your idea (please, see the screenshot from Block::Code help).
But in order to accelerate workaround, indeed it would be nice to consult with build log.
But I couldn't find it. Have you en idea where it's located ?
christobal:
Post-build messages are displayed in the "Build log" tab or in the generated Build Log html file.
Right at the end of the Build log, you should see something like:
--- Code: ---Output file is ..\result\Core0.elf with size 406.01 KB
[100.0%] Running target post-build steps
tricore-objcopy -O ihex ..\result\Core0.elf ..\result\Core0.hex
Process terminated with status 0 (0 minute(s), 9 second(s))
0 error(s), 0 warning(s) (0 minute(s), 9 second(s))
Build log saved as:
--- End code ---
