mysql already makes sure that the compiler emits position-independent code when appropriate, namely when compiling shared objects. The mysql build system puts its own flag behind the CFLAGS, overriding whatever was set before. Additionally, forcing applications into PIC mode will just slow them down (mysql not only provides shared objects but also applications). Last but not least OpenWrt's $(FPIC) can cause build failures. This is the case currently for AARCH64: net_serv.o: In function `my_net_init': net_serv.cc:(.text+0x28): relocation truncated to fit: R_AARCH64_LD64_GOTPAGE_LO15 against symbol `my_malloc' defined in .text section in ../mysys/libmysys.a(my_malloc.o) net_serv.cc:(.text+0x28): warning: Too many GOT entries for -fpic, please recompile with -fPIC /data/bowl-builder/aarch64_cortex-a53/build/sdk/staging_dir/toolchain-aarch64_cortex-a53_gcc-7.3.0_musl/bin/../lib/gcc/aarch64-openwrt-linux-musl/7.3.0/../../../../aarch64-openwrt-linux-musl/bin/ld: final link failed: Symbol needs debug section which does not exist collect2: error: ld returned 1 exit status Makefile:955: recipe for target 'mysqld' failed make[7]: *** [mysqld] Error 1 Remove $(FPIC) from TARGET_CFLAGS to address all of the above.
