Dear Sergei, You are right. My pcre version of cross compile is 8.30. Now I upgrade it to 8.37. Then I meet the another issue about strerror prototype define because it's different with my Linux 3.1.4.27.

Dear Sergei,
My tool chain support atomic oops, but HAVE_IB_GCC_ATOMIC_BUILTINS will not set because I use cross-compiling. (from storage/xtradb/CMakeLists.txt rule) Yes. I use "-DHAVE_IB_GCC_ATOMIC_BUILTINS=1" instead of "-DXTRADB_OK=1" to work around this issue because my tool chain really support atomic opps. As you said, I will meet the cross compile issue.

Could you give me some advice?
pcre_stack_guard was our addition to pcre to fix stack overflow issues. we have pcre in the source tree and it was patched to have pcre_stack_guard. We've also submitted the patch upstream and it got into pcre-8.34 (iirc). So our CMakeLists.txt tests whether pcre_stack_guard is present in the system pcre and if not - uses bundled pcre. I suspect that your native system pcre is 8.34 or later and your cross-compilation pcre is older, so cmake thought that it can use system pcre and later that failed. You can fix it either by upgrading your cross-compilation pcre or by forcing bundled pcre. Regards, Sergei
