libunwind fail

Post by lamer »

Before libunwind i had nice stacktraces within my C++ AI (but not 100% accurate +- 2-3 lines).
But with 98.0.1-xxx i got only "??:0 ??" instead of stacktrace.

Code: Select all

How to use libunwind with AI, or how to revert CrashHandler?

These are paths where CrashHandler tries to find debug symbols.

Code: Select all

<DEBUG>1 /home/user/.spring/engine/98.0.1-test/AI/Skirmish/CircuitAI/0.1//libSkirmishAI.soso.dbg
<DEBUG>2 /home/user/.spring/engine/98.0.1-test/AI/Skirmish/CircuitAI/0.1//libSkirmishAI.so.dbg
<DEBUG>3 /usr/lib/debug/home/user/.spring/engine/98.0.1-test/AI/Skirmish/CircuitAI/0.1//libSkirmishAI.soso
<DEBUG>2 /home/user/.spring/engine/98.0.1-test//spring.dbg
<DEBUG>3 /usr/lib/debug/home/user/.spring/engine/98.0.1-test//spring
<DEBUG>1 /usr/lib//libc.so.66.dbg
<DEBUG>2 /usr/lib//libc.so.6.dbg
<DEBUG>3 /usr/lib/debug/usr/lib//libc.so.66
Apparantly something wrong is going on there
