Errors when linking math lib. - pdaragon - 25-09-2020 Hello, I try to import a Keil project published by Semtech (firmware of the LoRa SX1261 evaluation kit). I almost succeeds, but face 5 remaining errors when the linker searches for <math.h> following functions: rint, round, floor, ceil. I tried to change several options in "Linker setttings/Library selection", but without success. Please could you help. I attach the .ebp project with this post (STM32L476RG HAL source files has been removed to limit zip file size to less than 1Mb). Thanks and regards Pascal RE: Errors when linking math lib. - Polarisru - 14-04-2022 (25-09-2020, 06:59 PM)pdaragon Wrote: Hello, You probably need to define math library under project libraries, I don't see any definition there. I mean Build options->Linker settings->Libraries Just put a single "m" there (without quotes). You will see "-lm" in you compiler output then. |
