L6665W: Neither Lib$$Request$$armlib Lib$$Request$$cpplib defined and Anonymous Symbol cause by weak functions (RVDS60)

I'm trying to port code that has been compiled using ADS5.8 to a new beta compiler RVDS6.0 (LLVM based).

I have 2 problems:

1. weak function

I got the following error during linking:

Error: L6654E: Rejected Local symbol [Anonymous Symbol] referred to from non group member my_main.o(.debug_info)

Error: L6654E: Rejected Local symbol [Anonymous Symbol] referred to from non group member my_main.o(.debug_info)

I think the errors above caused by weak functions

extern int my_init_device(void) __attribute__ ((weak));

int my_init_device(void) __attribute__ ((weak))

{    return(0); }

Currently, to bypass it, I temporarily commented out the above and made it as a non-weak function.

2.

Warning: L6665W: Neither Lib$$Request$$armlib Lib$$Request$$cpplib defined, not searching ARM libraries.

Error: L6411E: No compatible library exists with a definition of startup symbol __main

I have something like the following in my init code:

IMPORT __main 

B __main

Also, I created an archive and this init code is part of the archive, then I linked this archive with a user object code.

The code was compiled and linked with earlier RVDS or ADS.

Thanks,
