Hi,
we're using a library which is written in C++ and is using exceptions. As stated here Zephyr has C++ support including exceptions.
Following the docs I set

...
CONFIG_CPLUSPLUS=y
CONFIG_LIB_CPLUSPLUS=y
CONFIG_NEWLIB_LIBC=y
CONFIG_EXCEPTIONS=y
CONFIG_NEWLIB_LIBC_NANO=n
...
But this leads to a linker error:
fini.c:(.text.__libc_fini_array+0x20): undefined reference to `_fini'
When removing
CONFIG_NEWLIB_LIBC_NANO=n
the code is being compiled with a warning that CONFIG_EXCEPTIONS is set to 'n' because of unsatisfied dependencies (!NEWLIB_LIBC_NANO). In this case thrown exceptions are not catched. Instead of running the catch-path the code is running into _exit in libc-hooks.c which is part of newlib.
So, does anybody know how to enable the exception support? Am I missing some more CONFIGs?
Regards,
Oliver
