client.c:178:24：错误：调用未声明的函数“rb_tainted_str_new2”； ISO C99 及更高版本不支持隐式函数声明

问题描述 投票：0回答：1

我尝试在 macOS Sonoma 14.2.1 上安装 mysql2 gem，首先收到错误：

> gem install mysql2
...
ld: library 'zstd' not found
...

然后：

> gem install mysql2 -- --with-ldflags=-L(brew --prefix zstd)/lib
(works fine)

所以实际上我正在做的是（来自另一篇 Stack Overflow 帖子）：

> gem install mysql2 -v '0.5.3' -- --with-opt-dir=(brew --prefix openssl) --with-ldflags=-L(brew --prefix zstd)/lib
...
client.c:178:24: error: call to undeclared function 'rb_tainted_str_new2'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  VALUE rb_sql_state = rb_tainted_str_new2(mysql_sqlstate(wrapper->client));
                       ^
...

我找不到如何解决这个错误

解决方案是添加 

--with-cflags="-Wno-error=implicit-function-declaration"

例如

gem install mysql2 -v '0.5.3' -- --with-opt-dir=(brew --prefix openssl) --with-ldflags=-L(brew --prefix zstd)/lib --with-cflags="-Wno-error=implicit-function-declaration"
