Unable to use headers CW IDE v10.5 for MPC56xx

[gregorykabila]

Hello, I want to use headers such as stdio.h, math.h ... and so on.

However, whenever i use headers, errors occured.

example errors using math.h - sin fuction :
Link failed.
mingw32-make. *** [project.elf] Error 1
undefined: '_d_dtof' Referenced from 'main' in main_c.obj
undefined: 'sin' Referenced from 'main' in main_c.obj

What should i do??

Hello Gregory,

The problem with the undefined routines might be caused by missing EWL/Runtime libraries.

Can you please check if your project properties includes libc* and librt*? (Project Properties -> C/C++ Build -> Settings -> PowerPC Linker/ Input -> Library Files):

You should see two e.g.

.../libc_E200z750_VLE.a

.../librt_E200z750_VLE.a
