Error: hammer ABI contains Genode-internal symbol '__bss_start'

Hi Guido,

thank you for clarifying your posting. Don't worry. It's all fine.

In my experience, the creation of the ABI-symbols file is a step that
comes not before the actual porting work is finished. A target can
use/link a library without an ABI symbols file when built from the build
directory (not from a depot source archive). So during the repetitive
porting process, the library can be repeatedly linked and tested from
within the build directory using a regular target. The packaging does
not stand in the way here.

The creation of the symbols file it is typically a one-off task with
subsequent manual curation - at packaging time, not at library-porting
time. As far as I remember, I have rarely called the abi_symbols tool
more than once while porting/packaging a library.

It is clear by now, that our typical workflow needs to be better documented.

Would the following command possibly work for you?

  abi_symbols <your-library>.lib.so | grep -v '#' > <your-symbols-file>

Cheers
Norman
