Buildroot commitfabcd7c8ccbumped the package from 28.0 to 30.0 which includes upstream commita01cb6e63fthat was first included in version 29.0 and added among others -fstack-protector-all to cxx_flags guarded with a new configure option ENABLE_HARDENING which default to ON. This commit causes build errors with toolchains with SSP support: [ 44%] Linking CXX executable ../bin/bitcoin /home/autobuild/autobuild/instance-40/output-1/host/lib/gcc/i686-buildroot-linux-musl/15.2.0/../../../../i686-buildroot-linux-musl/bin/ld: CMakeFiles/bitcoin.dir/bitcoin.cpp.o: in function `fs::PathToString(fs::path const&)': bitcoin.cpp:(.text+0x4c): undefined reference to `__stack_chk_fail_local' Upstream later removed the forementioned configure option with commit00ba3ba303that was first included in version 30.0 so we need to remove -fstack-protector-all from CMakeLists.txt.

Subject: [PATCH] CMakeLists.txt: Don't force -fstack-protector
|
|
|
|
This allows the environment to decide whether SSP should be used or
|
|
not, for example to support toolchains that don't have SSP support.
