_impure_ptr and __locale_ctype_ptr undefined
Hi,
I am trying to link a library built with arm-none-eabi-gcc with ARMC6 under MBed Studio. During link time I have _locale_ctype_ptr and _impure_ptr which are undefined.
After googling them It looks like they are coming from the newlib used by gcc.
Is there any chance to have armcc linking with this library ?

Hi!
Unfortunately linking to a library built with GCC_ARM using a different compiler is not a supported method. If the library is not using a compatible ABI I would recommend either recompiling the library in ARMC6, or compile your application using GCC_ARM.
Mbed CLI by default will install the GCC_ARM toolchain as the default compiler:
https://os.mbed.com/docs/mbed-os/v5.11/tools/installation-and-setup.html
how was the library compiled? Looks like does not use compatible ABI . Can you recompile the lib?
