C Library for FuSa

RTL

Hello!

First of all, I am very new to Keil uVision.

I downloaded Arm Compiler 6.6 C Library for Functional Safety 6.6.B. Did the installation and saved it to Keil_v5/ARM/ARM_Clib. Then added the ARM_Clib/include to Options->C/C++ (AC6)->Include Paths.

I am trying to use the isinf(x) function from math.h, but when I try to compile I get this error:

.\Objects\myproject.axf: Error: L6218E: Undefined symbol __ARM_isinff (referred from mylibrary.o).
Not enough information to list image symbols.
Not enough information to list load addresses in the image map.

extern of this __ARM_isinff is defined in the end of the math.h file, but from there it leads to nowhere (nothing happens when I try to go to the definition of it).

Am I missing some steps in my setup?

    Hi again Reimo,

    Apologies, I was wrong, __ARM_isinf and __ARM_isinff _are_ present in the FuSa C library, but are declared as "helper" functions so are not listed in the user documentation.

    Have you added the FuSa C library to your link line and turned off linking with the standard libraries?
    The docs have a section called "Using the FuSa C Library" which you need to follow.
    Here's an example extract showing what to do:

    armclang --target=arm-arm-none-eabi -march=armv7-a -c entry.S
    armclang --target=arm-arm-none-eabi -march=armv7-a -fno-builtin -ffp-mode=full -nostdlibinc -nostdlib -I /ArmCLib6.6.AArmv7A+R/include -c test.c
    armlink --no_scanlib --no_startup /ArmCLib6.6.AArmv7A+R/lib/fusa_clib_armv7a_softfp_ropi.l entry.o test.o --entry=entry_point

    Hope this helps,

    Stephen
