Hello everyone, I am using OpenWrt 19.07. I got the following error while compiling the "olsrd" package.
error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O)
After doing some research, I saw that it might be related to the compilation flags and I changed the
TARGET_CFLAGS += $(FPIC) to
TARGET_CFLAGS += -O2 in the makefile of the "olsrd" package. But this time I got the following error.
collect2: error: ld returned 1 exit status
What could be the solution to these problems?
