Regarding u-boot 2010.03 compilation with gcc 7.3(latest gcc in yocto)

Praveen Reddy

Hi All,

When I am compiling u-boot 2010.03 with gcc 7.3 in yocto, It is throwing errors regarding multiple definition of the all extern inline functions in u-boot. It seems this gcc version is not supporting external inline functions.

Below is sample error log

---/build/tmp/work/tng-poky-linux-gnuspe/u-boot-qoriq/2018.03+fslgit-r0/u-boot-2010.03/include/asm/bitops.h:256: multiple definition of `find_next_zero_bit'
hello_world.o:/home/praveen/tng-bsp/build/tmp/work/tng-poky-linux-gnuspe/u-boot-qoriq/2018.03+fslgit-r0/u-boot-2010.03/include/asm/bitops.h:256: first defined here
libstubs.a(stubs.o): In function `ext2_test_bit':
---/build/tmp/work/tng-poky-linux-gnuspe/u-boot-qoriq/2018.03+fslgit-r0/u-boot-2010.03/include/asm/bitops.h:330: multiple definition of `ext2_test_bit'

below is piece of code from bitops.h from where error is coming

extern __inline__ int ext2_test_bit(int nr, __const__ void * addr)
    __const__ unsigned char    *ADDR = (__const__ unsigned char *) addr;

    return (ADDR[nr >> 3] >> (nr & 7)) & 1;

coming Any idea what is wrong and how to fix the problem?

Is it the right place to ask question about freescale u-boot compilation in yocto.
