Bug ID: 103166
Summary: [12 regression] wrong dependency on getentropy on
newlib-based targets
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
Since r12-5066, I've noticed numerous link failures on aarch64-none-elf like:
FAIL: g++.dg/concepts/expression.C -std=gnu++17 (test for excess errors)
Excess errors:
/libstdc++-v3/src/c++11/random.cc:179: undefined reference to `getentropy'
/libstdc++-v3/src/c++11/random.cc:179:(.text._ZNSt12_GLOBAL__N_117__libc_getentropyEPv+0x10):

Maybe there's something wrong with the detection of HAVE_GETENTROPY in
configure?
