rust not linking on Linux

["Dr. Thomas Orgis" <thomas.orgis%uni-hamburg.de@localhost>]

Hi,

for lang/rust from CVS head to build on Linux, I need this patch:

Otherwise, it doesn't find libunwind during linking or at some point at runtime.

This is on both Linux setups I test, consistently. I wonder: Is there
someone that is able to build rust without these changes? Some other
library directory magic? This is both with a custom toolchain and the
system compilers from Ubuntu.

I do not need these changes for the rust in 2023Q4.


Alrighty then,

Thomas
