Adding the -fgnu89-inline flag fixes the warnings, by enabling "traditional GNU semantics for inline functions when in C99 mode".

编译程序的时候总报 “内联函数声明但未定义” 的警告。

解决方法就是在编译时加上-fgnu89-inline

再次编译就没有问题了。


2、我用的是 cmake 编译，增加参数 -fgnu89-inline ，参考代码如下：

add_definitions(-fgnu89-inline)

程序编译的时候会报错： warning: 'delay' defined but not never defined 【问题原因】 声明为static的函数不能被其他文件所使用，如果其他文件include uart.h。那么就会报上面的错误。 【解决办法】 解决的办法很简单，将头文件中的声明转移到.c文件中就可以了，即将函数delay的声明从uart.h移动到uart.c文件的开始就可以了。 ...

以inline修饰的函数叫做内联函数，编译时C++编译器会在调用内联函数的地方展开，没有函数压栈的开销，内联函数提升程序运行的效率。编译时加上 -fgnu89-inline 编译就没有问题了。注意不是在终端make后面加，而是在你对应的Makefile文件的gcc 后面。如：CC := $(CROSS_COMPILE)gcc。编译程序的时候总报 “内联函数声明但未定义” 的警告。

在编译时添加选项 “-fgnu89-inline”，重新编译即可。 注意不是在“make”后面添加“-fgnu89-inline”，是在Makefile里在使用gcc编译的地方添加“-fgnu89-inline”。

有时候在使用gcc编译程序时，会遇到这样的报错： warning: inline function xxx declared but never defined 翻译成中文就是，使用了某个内联函数，但是没有找到定义，这个原因在于gcc编译器对于inline函数处理的方式不同导致。简单来说要搞清楚以下几个方面，便于查找资料详细了解： 1. C语言的标准： 目前C语言有几个...

错误放在最开始： //原来头文件是这么写的： public: inline bool operator==(Snapshot const&); //后来的cpp文件是这么写的： inline bool Snapshot::operator==(Snapshot const&snap) { 然后报错是这样的： undefined reference to `Snapshot::operator== 随后把inline去掉就正常了。 网上查了一下问题..

C语言中的static一直都是比较头疼的问题，但是高质量的C 程序往往都将static用的非常精妙。 今天在程序使用static的时候遇到一个问题，定义一个局部可见的程序的时候使用了static，在头文件声明后产生了“warning 'XXX' declared 'static' but never defined”的警告。 XX.c文件中: static int test(void) {...
