regex implementation for arm-none-eabi toolchain

[newbie_stm32]

Hi Community, I am using a cross-compiled library with STM32CubeIDE which uses regcomp, regexec, and regerror methods and gives linker error while building.

Is there a way to cross-compile the regex library separately and link it to the current project?

Why is only regex.h distributed with toolchain and not with its definition?
