Hi, Dear NXP guys

as below screenshot, when I specified "--no-as-need" in S32DS C Compiler settings,

the powerpc-eabivle-gcc.exe told me that it can NOT recognized this option.

I have to fix some lib link order issue by using this gcc option.

how can I archive this ? or is there other ways that S32DS supported ?

Hi, 

the "no-as-needed" is linker (ld) option and can be added into linker settings:

Hi, 

I tried both the "--no-as-need" and "--no-as-needed" option in Linker, but seem neither of them work.

1. put fmc_bsp_os lib before fmc_sm, build project, many "undefined reference to FmcBspXxxx" error, those FmcBspXxxx functions should be already in fmc_bsp_os lib.

2. put fmc_bsp_os after fmc_sm, the "undefined reference to FmcBspXxxx" disappeared,

    this means that FmcBspXxxx exist in fmc_bsp lib,

    but the linker can not find it if the fmc_bsp_os lib is located before fmc_sm lib (no matter that --no-as-need is added or not).

Hi, 

I'm assuming that the error is not related to any linker option. Can you please share your project here or you can send it on jiri.kral@nxp.com ?
