那位遇到过这种问题:AIX上gcc编译器对函数复用报错,而且曲解了.h文件中的函数定义.

在文件/root/hiplinkxs/src/hllib/include/HLlibShare.h的150行,实际函数定义是这样的:
std::string HLstringSQLEncode(unsigned long data);

    • ../rdb/src/HLRDBschedulableGroup.cpp中726行调用是HLstringSQLEncode( schedule->tScd.tWeekly.lDays ),参数是long类型. -mike20030405(mike); 2006-1-11 (#2713194@0)
      • 调用的时候强制转换成unsigned long 试试。HLstringSQLEncode( (unsigned long)(schedule->tScd.tWeekly.lDays) ); -canadiantire(轮胎-M.I.N.K.); 2006-1-12 (#2714511@0)
        • 函数原型中缺少一个std::string HLstringSQLEncode(long)定义.加上后就可以了. 多谢. -mike20030405(mike); 2006-1-12 (#2714741@0)
