Hi, I am using GCOV for test coverage in a project using instructions for freestanding environment Below are the flags i use. CFLAGS += -fprofile-arcs -ftest-coverage -fprofile-info-section LFLAGS += -lgcov --coverage With these flags, thigs works fine with toolchain version 12.3 but i am facing below error if i upgrade to toolchain version 14.2 (AArch32 bare-metal target). /opt/arm-gnu-toolchain-14.2.rel1-x86_64-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/14.2.1/../../../../arm-none-eabi/bin/ld: /opt//arm-gnu-toolchain-14.2.rel1-x86_64-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/14.2.1/thumb/v8-m.main+fp/softfp/libgcov.a(_gcov.o): in function `gcov_read_bytes': libgcov-driver.c:(.text.gcov_read_bytes+0x10): undefined reference to `fread' I found that if i pass '-lgcov --coverage' before '-lc' in linking, then my problem is fixed. + LFLAGS += -lgcov --coverage LFLAGS += -lc - LFLAGS += -lgcov --coverage Need help to understand why such changes/library order is are not required for toolchain version 12.3 ? Regards, Wasim
