</div>
<div>
<p class="MsoNormal">codesourcery codebench arm eabi version uses newlibc.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Now I aware that this is the problem of stdint.h. And, codesourcery toolchain also has stdint.h header file at same place of stdio.h<o:p></o:p></p>
<div>
<p class="MsoNormal">Generally, Clang has "lib/clang/3.0/include" default search path. <o:p></o:p></p>
<div>
<div>
<p class="MsoNormal">If I added codesourcery toolchain path for stdio.h with -I option, stdint.h has been loaded at the specified toolchain path first cuz clang's default search path priority moved back.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In my case, when I busted codesourcery toolchains stdint.h, it's okay to build.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">And also it was okay cuz clang called /usr/include/stdint.h first on Unbuntu linux.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">How could I avoid this conflict, not to be removed stdint.h of toolchian?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I think arm_neon.h in clang lib folder can handle this.<o:p></o:p></p>

perfectly reasonable for gcc’s headers to define int32_t as long).<o:p></o:p></p>
