Strip error: Unable to recognise the format of the input file

strip --strip-unneeded ButtonLED_ti_reloc_strip.out 
BFD: ButtonLED_ti_reloc_strip.out: warning: sh_link not set for section `.mspabi.exidx'
strip: Unable to recognise the format of the input file `ButtonLED_ti_reloc_strip.out'

I tried to strip a file compiled with the CCS. The project was set with -g and -r (debug info and relocatable).

I wanted to strip the file and check the differences since I am working with ELF files and having a reduced amount of sections would help me a lot.

Unfortunately, seems like I can't do it due to the error in the title, can anyone tell me why is that happening ?

Thank you.

Use "strip430" instead. Note that a "relocatable executable" file is not a normal ELF file, so it's not terribly surprising that generic ELF tools might have a few problems with it.

There is not msp430 command in my OS. How are you able to use it ?

strip430 --strip-unneeded ButtonLED_ti_reloc_strip.out 
strip430: command not found

I assume that when you said "compiled by CCS" you meant with the TI compiler. The strip utility that ships with the TI compiler is called strip430.

If you're using GCC to compile, make sure that the version of strip that you are calling is the version that gets built with the MSP GCC. To be safe, invoke it through its long name, which should be something like msp430-non-eabi-strip

You were right, I changed directory to /opt/ti/ccsv6/tools/compiler/ti-cgt-msp430_4.4.5/bin and executed it again.

cd /opt/ti/ccsv6/tools/compiler/ti-cgt-msp430_4.4.5/bin/
./strip430 --strip-unneeded [file_to_strip]

Thanks !
