Subject: [PATCH] stacktrace_libgcc-inl.h: fix build for some ARM toolchains
|
|
|
|
On OpenWrt when bulding for arm_cortex-a15_neon-vpfv4 or
|
|
arm_cortex-a9_vfpv3-d16, the build errors out due to an undefined symbol
|
|
_URC_NORMAL_STOP. This usually happens when the required header
|
|
(typically <unwind.h>) is not included, or the toolchain's unwind
|
|
implementation does not provide this definition.
|
|
|
|
Error:
|
|
src/stacktrace_libgcc-inl.h: In function '_Unwind_Reason_Code libgcc_backtrace_helper(_Unwind_Context*, void*)':
|
|
src/stacktrace_libgcc-inl.h:69:12: error: '_URC_NORMAL_STOP' was not declared in this scope
|
|
69 | return _URC_NORMAL_STOP;
|
|
|
|
|
|
|
A work-around is to use URC_END_OF_STACK.
