System Workbench for STM32


Type make: *** [blablabla.elf] Error 1 when using math.h acos() and co.

Hello,
I had this problem now for days and am close to suicide. I tried all i could, but did not solve it.
I use SW4STM32 in combination with STM32CUBEMX and do create a simple project for an MCU.
Everything works fine except when I want to use some functions of “math.h” sin(x) works but acos(x) does throw the error: Type make: *** blablabla.elf Error 1.
This does not work:
float x = 123;
float y = acosf(x);
This works:
float x = 123;
float y = sin(x);
y = sinf(x);

Can someone please help me? I do not know what extra information I need to give you so please tell me if there is something missing.

Hi,

There is a small bug in the linker invokation when using the math library; could you add explicitly option -lm on Project >> Properties >> C/C++ Build >> Settings >> MCU GCC Linker >> Libraries in the Libraries section on top of pane? You may leave the Use C math library (-lm) option at bottom of pane checked, it does no harm but, currently, it does no good either.

In next release the checkbox will be working OK and the explicit reference will no more be needed (but leaving it in will not harm either...)

Thank you very much, you saved my day!
