.elf not found

[lixu]

Hi,

I am using S32DS working on MPC5748G.

The same project I was debugging, the first time it successfully, but the second time it showed :    

make: *** [makefile:80: lwip_uart_.elf] 

D:\S32_DS\workspaceS32DS.power.21\lwip_uart_\Debug_FLASH\lwip_uart_.elf not found

Indeed my .elf files have disappeared under this path. 

Could you tell me how to solve this problem， please.

Thanks and best regards,

Li Xu

Hello,

are you able to recompile the project? If yes, then simply compile it and the elf is automatically generated by default.

compile failed. It shows:

make: *** [makefile:80: lwip1.elf] Error 1    lwip1    C/C++Problem

D:\S32_DS\workspaceS32DS.power.21\lwip1\Debug_FLASH\lwip1.elf not found

Its hard to say.

Could you share whole output from console? So I can see where is the issue?

best regards,

Hi, 

your project can't be compiled because of linker error(s). You need to fix the multiple "buffer" definition first. 

It is your custom project or example?

Hi,

Yes, that's the question.

I always thought it was an error during "debug", so I always thought it had nothing to do with the code. But it was actually an error during "building".

Thank you very much for your reminding.

Hello,

elf file is a product of compilation. So I guess you cleared your build and then elf is deleted.

Simply compile the project with elf as output file set.

You can have a look on out HOW TO guides:
