I am trying to build my project using Cmake to replace the work of the IDE（S32DS for GHS）.

How to modify IDE makefile scripts to adapt to C make syntax?

> post-build:  
> -gstrip -r=.debug\_frame S32K344\_DEMO\_20.elf  
> -@echo ’ ’

Script statements are used to address: The GHS toolchain does not generate DWARF Call Frame information that is suitable for unwinding the call stack.

I have already tried the C make statement：

> set(CMAKE\_STRIP “-gstrip”)  
> add\_custom\_command(TARGET ${target\_name}.elf POST\_BUILD  
> COMMAND ${CMAKE\_STRIP} -r=.debug\_frame ${target\_name}.elf )

Does anyone have similar experience and can you give me some advice? Thank you very much.

How about this:

> [@Bruce\_Ye](#):
>
> set(CMAKE\_STRIP “gstrip”)  
> add\_custom\_command(TARGET ${target\_name}.elf POST\_BUILD  
> COMMAND ${CMAKE\_STRIP} -r=.debug\_frame “$\<TARGET\_FILE:${target\_name}.elf\>” )

The `-` prefix is a Makefile syntax that won’t work as a straight command in CMake. Then the other change is to use `$<TARGET_FILE>` instead of hoping that the command is executed in the same directory as the file.

Thank you for your suggestion. But it did not solve the problem as expected. Cmake error: ‘gstrip’ is not an internal or external command, nor is it a runnable program or batch file.

In S32DS IDE，during the compilation process, the statement works like this:

> Building target: S32K344\_DEMO\_20.elf  
> Invoking: GHS C Linker for ARM Standalone  
> ccarm --gnu\_asm -g -dwarf2 -T “D:/D/workpalce/S32k344/S32K344\_DEMO\_20/Projectcode/Mcal/Platform\_TS\_T40D34M10I0R0/build\_files/ghs/linker\_flash\_s32k344.ld” -e Reset\_Handler -nostartfiles -cpu=cortexm7 -thumb -o “S32K344\_DEMO\_20.elf” ./src/main.o ./RTOS/Platform/Arch\_Extend.o ./RTOS/Platform/Arch\_Irq.o  
> …  
> Finished building target: S32K344\_DEMO\_20.elf  
> **gstrip -r=.debug\_frame S32K344\_DEMO\_20.elf**

Once again, I’m grateful for your support.

Can you please share the command line that is failing? Digging into the generated makefiles to find the actual written command would help too.

I also tried to modify CMAKE-STRIP to “strip” and “- gstrip”, but it also failed

There are quotes somewhere they shouldn’t be. It is looking for a file named `"gstrip"` in `PATH`.

In make syntax a leading `-` is used to ignore the exit code of a command line.  
So the program to use, is definitely `gstrip`.

The IDE adds one ore more path variables, so the program can be found when it calls its make.  
You can see in your log, that it simply calls `ccarm` without absolute path.

So you need to search for the `gstrip` executable, or give it an absolute path. It’s most likely in the same path as your `ccarm`, but may be in a different utility directory. I would suggest to do it similarly as you specify the compiler.

I have searched for the `gstrip` executable, give it an absolute path, like this:

Now, it wroks. Thank you for your help.

I did not specify the correct path for gstrip. After modification, it wroks. Thank you for your help.
