hi ：

in the gcc-arm-none-eabi-6-2017-q1-update-win32 ver

gcc-arm-none-eabi-6-2017-q1-update-win32/bin/../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/lib/thumb/v7-m\libc.a(lib_a-fini.o): In function `__libc_fini_array':
fini.c:(.text.__libc_fini_array+0x26): undefined reference to `_fini'
collect2.exe: error: ld returned 1 exit status

but in gcc-arm-none-eabi-6_2-2016q4-20161216-win32 is ok

What's your command-line?

[lzyr (lzyr163)]

arm-none-eabi-gcc.exe -mcpu=cortex-m3 -ffunction-sections -fdata-sections -fno-exceptions -DSTM32F10X_HD -DUSE_STDPERIPH_DRIVER -D__ASSEMBLY__ -DSTM32F103VC -mthumb -Os

arm-none-eabi-g++.exe -s -Wl,-Map -Wl,--gc-sections -n -Wl,-cref -mcpu=cortex-m3 -mthumb -Xlinker --gc-sections -nostartfiles -Wl,-Map,link.map --specs=nano.specs -TSrc/BSP/Start/Flash.ld

when use --specs=nano.specs link is ok

dont use --specs=nano.specs link is fini.c:(.text.__libc_fini_array+0x26): undefined reference to `_fini'
collect2.exe: error: ld returned 1 exit status

Hi lzyr,

Why would you not want to use the specs file? The specs file is necessary to tell the linker what library(s) and startup file(s) to link in what order.

Thanks,
Tejas.

Hi lzyr,

Have you tried using -specs=nosys.specs?

Best regards.

[lzyr (lzyr163)]

yes use --specs=nano.specs too be make bin small.

only use -specs=nosys.specs ,it link can pass.

use -specs=nosys.specs failed.

but at 2016q4 is ok。

link lib:

/DISCARD/ :
    {
        libc.a ( * )
        libm.a ( * )
        libgcc.a ( * )
        libnosys.a(*)
    }
