| Subject: [PATCH] Makefile: add -fno-builtin |
| |
| Build with gcc 10 fails on: |
| |
| /srv/storage/autobuild/run/instance-2/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: src/foundation/startup.o: in function `reset_handler': |
| /srv/storage/autobuild/run/instance-2/output-1/build/am33x-cm3-11107db2f1e9e58ee75d4fe9cc38423c9a6e4365/src/foundation/startup.c:177: undefined reference to `memcpy' |
| |
| This is due to the fact that gcc 10 replaces the following statement by |
| a memcpy call: |
| |
| *puldest++ = *pulsrc++; |
| |
| To fix this build failure, add -fno-builtin |
| |
