error C3688: invalid literal suffix '__FSTREXP'; literal operator or literal operator template 'operator ""__FSTREXP' not found

error C3688: 文本后缀“__FSTREXP”无效；未找到文文本运算符或文本运算符模板“operator """"__FSTREXP”

出错代码如:

("xxxx: "__FILE__" "__FUNCTION__" line:%d. \r\n")

 

I found a hint which might help you there the problem was a missing space between "(" and __FUNCTION__ .
So you should try it with some spaces before and after __FUNCTION__, i.e.:
BDISPFUNCDAT("context %s "   __FUNCTION__   " %s\n", "preset", "start");
