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
