<br>
Thanks for you suggestions.<br>
<br>
On step 4.7 (<a href="http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-static.html" rel="noreferrer noreferrer noreferrer" target="_blank">http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-static.html</a>), I replaced GCC 6.2.0 by GCC 6.5.0,<br>
And this time, step 4.7 passed, then step 4.8 (<a href="http://clfs.org/view/clfs-embedded/x86/cross-tools/libc.html" rel="noreferrer noreferrer noreferrer" target="_blank">http://clfs.org/view/clfs-embedded/x86/cross-tools/libc.html</a>) also passed,<br>
<br>
But on step 4.9 (<a href="http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-final.html" rel="noreferrer noreferrer noreferrer" target="_blank">http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-final.html</a>), the error below occurred, could you give me suggestion again? Thanks.<br>

Newer versions of GCC have different default settings for what is<br>
considered an error or a warning as compared to older versions of GCC.<br>
I believe that GCC releases from version 7 onwards will hit this issue<br>
when building GCC 6.3.<br>
<br>
I believe that newer releases of GCC version 6 (like version 6.4 or<br>
6.5) should fix this. You could try using a newer version of GCC 6.<br>
Or you can have a try at applying this patch from OpenEmbedded:<br>

<br>
Sorry, I don't have a better or more detailed answer for you right now.<br>
Thanks,<br>
Andrew<br>
