- Subject: [PATCH] add proper check for detecting header <execinfo.h>
- domoticz.cpp currently assumes that on GNU/Linux systems header
- <execinfo.h> is available. But that is not true. Since it provided by
- C library and uClibc can be built without backtrace support. And in
- such cases we get following build error.
- domoticz-3.4834/main/domoticz.cpp:48:22: fatal error: execinfo.h: No such file or directory
- #include <execinfo.h>
- ^
- compilation terminated.
- Instead of depending on __gnu_linux__, add check for detecting
- presence of <execinfo.h> and guard code for dumpstack accordingly.
- This build failure is detected by Buildroot autobuilder.
