Fix build with gcc 10
|
|
Add missing extern to gBm to fix the following build failure with
|
-fno-common which is enabled by default with gcc 10:
|
|
/usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-0/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: bookmark.o:(.bss+0x10): multiple definition of `gBm'; gpshare.o:(.bss+0x24): first defined here
