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.

My solution is commend out strerror define in storage/connect/filamvct.cpp and
storage/connect/tabvct.cpp files.
#if defined(UNIX)
// Add dummy strerror (NGC)
//char *strerror(int num);
#endif // UNIX
Is it right? Or have better solution?
Best Regards,
Johnson

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.

Sergei
