Subject: [PATCH] Proper detection of cxxabi.h and execinfo.h
|
|
|
|
The current code in webrtc/base/checks.cc assumes that if __GLIBCXX__ is
|
|
defined and __UCLIBC__ is not defined, then both cxxabi.h and execinfo.h
|
|
will be available.
|
|
|
|
Unfortunately, this is not correct with the musl C library:
|
|
|
|
- It defines __GLIBCXX__
|
|
- It does not define __UCLIBC__ (it's not uClibc after all!)
|
|
- But it also doesn't provide execinfo.h
|
|
|
|
Therefore, in order to make things work properly, we switch to proper
|
|
autoconf checks for cxxabi.h and execinfo.h, and only use the backtrace
|
|
functionality if both are provided.
