Description
I'm attempting to compile libc for an STM32L4R5 (Cortex-M4F) on a Linux system running kubuntu 22.04
I cloned the latest libc from the GitHub repo.
I am completely new to using the meson build system, but am willing to learn.
Any help would be appreciated.
After cloning the libc repo...
$ make distclean
$ make default CROSS=arm:cortex-m4_hardfloat
It seems to fail trying to compile cmocka for the ARM STM32 complaining about a missing setjmp.h which I assume should be provided by the local libc headers not the system. setjmp.h is in the libc/include directory.
The compiler invocation to compile cmocka.c does not include any reference to the local header files.
Is there a simple way to add the local libc headers to the cmocka.c build command ljne ?
The complete meson-log.txt file is attached here, but I don't see any reference to cmocka.c there so I'm not sure how helpful that will be.
Here is the final line of output from the build attempt
...
