PXS2010 Maths libraries not functioning

twp — Thu, 04 Jul 2013 14:51:52 GMT

I'm using Codewarrior 10.4 with a PXS2010 board and have enabled floating point support in the project by adding:

#define _EWL_FLOATING_POINT 1

to the build prefix files. The project is set to SPFP floating point support, however logf(x) is giving very strange results. Following on from comments in this thread...

https://community.freescale.com/message/302198#302198

I tried adding:

#pragma dont_inline on

...

#pragma dont_inline reset

around the code using the maths libraries which has fixed the problem. The previous thread mentioning problem this marked this issue as solved in version 10.3 libraries but I seem to be having this problem with 10.4 libraries. Is there a fix for this issue?

Hi twp,

Can you perhaps post the example project? I cannot reproduce it at the moment on my side.

Did you select "SPFP" or "SPFP_Only" in Floating point support dialog when the project was created?

Did you add #include <math.h>?

What results do you get with and without #pragma dont_inline?

Thanks for additional details.

Stan
