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