+++++++++++++编译Criteria.Tools.Executor错误
/opt/cBPM-android/criteria-lin/lib/libxerces-c.a(IconvTransService.o):IconvTransService.cpp:function xercesc_3_1::IconvLCPTranscoder::calcRequiredSize(char const*, xercesc_3_1::MemoryManager*): error: undefined reference to '__ctype_get_mb_cur_max'

解决方法：+++++++++++++ 在上面基础上，编译libiconv （静态库）
這似乎是NDK的BUG，在stdlib.h內有宣告出__ctype_get_mb_cur_max函數，但是卻沒有去實作它。如果出現這個問題，不建議直接修改NDK，要到libiconv目錄下，修改「libcharset/lib」目錄裡的「localcharset.c」檔案，在檔案最下面加上以下程式碼即可。

[root@localhost libiconv-1.14]# gedit /opt/cBPM-android/libiconv-1.14/libcharset/lib/localcharset.c

size_t __ctype_get_mb_cur_max(void){
    return 1;
}
保存，重新编译libiconv （静态库）

[root@localhost libiconv-1.14]# nm ./lib/.libs/libiconv.a |grep ctype_get_mb_cur_max
         U __ctype_get_mb_cur_max
0000060c T __ctype_get_mb_cur_max

//如果您指定了 -A 选项，则 nm 命令只报告与该文件有关的或者库或者对象名。
[root@localhost libiconv-1.14]# nm -A ./lib/.libs/libiconv.a|grep ctype_get_mb_cur_max
./lib/.libs/libiconv.a:iconv.o:         U __ctype_get_mb_cur_max
./lib/.libs/libiconv.a:localcharset.o:0000060c T __ctype_get_mb_cur_max
[root@localhost libiconv-1.14]#

[root@localhost criteria-lin]#  nm -A lib/lib* |grep ctype_get_mb_cur_max
nm: lib/libc.so：无符号
lib/libiconv.a:iconv.o:         U __ctype_get_mb_cur_max
lib/libiconv.a:localcharset.o:0000060c T __ctype_get_mb_cur_max
lib/libiconv.so:         U __ctype_get_mb_cur_max
lib/libiconv.so.2:         U __ctype_get_mb_cur_max
lib/libiconv.so.2.5.1:         U __ctype_get_mb_cur_max
nm: lib/libsqlite.so：无符号
nm: lib/libstdc++.so：无符号
lib/libxerces-c-3.1.so:         U __ctype_get_mb_cur_max
lib/libxerces-c.a:IconvTransService.o:         U __ctype_get_mb_cur_max

所以，编译Criteria.Tools.Executor时，需要 静态链接 /opt/cBPM-android/criteria-lin/lib/libiconv.a
