S32 DS,libraries support

zhouzy — Fri, 15 Sep 2023 02:52:30 GMT

when I bulid a project using S32 DS,there are some problems like:

Ld errors:undefined reference to 'floors'

Actually,floors is a function which is defined in <math.h>

FAE from agent gives me a solution and it works:

change the configuration in libraries support(properties->settings->Target Processor)：

newlib no I/O (-specs=nosys.specs) -> ewl_c no I/O(-specs=ewl_c9x_noio.specs)

sysroot is also modified automatically.

**********************************************

My Question is what are the meanings of these configurations about libraries support.

and can i get a detail documentation about all the settings of S32 DS

thanks a lot.

Hi,

you switched STD C library from NewLIB to EWL (old STD C library maintained by NXP) and there is included math library, normally is math library standalone lib archive. .

I recommend use NewLIB and simply add math library into your project like on screensthot. Right click on project name -> Properties -> C/C++ Build -> Settings -> Libraries:

Hi,

this settings is not related to S32DS itself - it is tool-chain dependent. This menu is different for IAR or for GCC in this case. It is standard GCC configuration - you can add compiler options, include paths, library paths, libraries, preprocessor macros and So on.

You can find more details in Help ->: Help Contents and search for Project Properties.
