macro parameters must be comma-separated 宏参数必须由逗号隔开

missing ‘(‘ after predicate 谓词后缺少‘(’

missing ‘(‘ in expression 表达式中缺少‘(’

missing ‘)’ after \\defined\\\ “defined 后出现‘)’

missing ‘)’ in expression 表达式中缺少‘)’

missing ‘)’ in macro parameter list 在宏参数表中缺少‘)’

missing ‘)’ to complete answer 完整的答案缺少‘)’

missing binary operator before token \\%s\\ 标识符“%”s前缺少二元运算符

missing expression between ‘(‘ and ‘)’ ‘(’与‘)’之间缺少表达式

missing terminating %c character 缺少结尾的 %c 字符

missing terminating > character 缺少结尾的 > 字符

missing whitespace after the macro name 宏名后缺少空白

multi-character character constant 多字节字符常量

no iconv implementation, cannot convert from %s to %s 没有 iconv 的实现,无法从 %s 转换到 %s

no include path in which to search for %s 没有包含路径可供搜索 %s

no macro name given in #%s directive #%s 指示中未给出宏名

no newline at end of file 在文件最后一行加上回车键

解释:在“Rationale for the C99 standard”一文中,有C99的相关信息:

A backslash immediately before a newline has long been used to continue string literals, as well as preprocessing command lines. In the interest of easing machine generation of C, and of transporting code to machines with restrictive physical line lengths, the C89 Committee generalized this mechanism to permit any token to be continued by interposing a backslash/newline sequence. c/c++代码的每一行后面有一个“结束符”,也就是newline。避免当被include的文件展开后,前一个文件的最后一行与后一个文件的第一行直接被连接成一行从而造成错误。

non-ISO-standard escape sequence, ‘\\\\%c’ 非 ISO 标准的转义序列,‘\\\\%c’

null character(s) ignored 忽略空字符

null character(s) preserved in literal 空字符将保留在字面字符串中

NULL directory in find_file find_file 中有 NULL 目录

octal escape sequence out of range 8 进制转义序列越界

^.

operator ‘%s’ has no right operand 操作符‘%s’没有右操作数

mes_函数第一个参数的传递,丢弃了指针目标类型限定。

parameter name missing 缺少形参名

passing argument 1 of 'send' makes pointer from integer without a cast 函数send的第一个integer型参数没有强制转换为pointer型

pasting \\%s\\ and \\%s\\ does not give a valid preprocessing token 毗连“%s”和“%s”不能给出一个有效的预处理标识符

poisoning existing macro \\%s\\ 对已存在的宏“%s”投毒

predicate must be an identifier 谓词必须是一个标识符

registering pragma with NULL handler pragma 注册为被 NULL 处理

registering pragmas in namespace \\%s\\ with mismatched name expansion 在命名空间“%s”中注册 pragma 时名称扩展不匹配
