The GCC compiler flags that control unused warnings include:

-Wunused-function
-Wunused-label
-Wunused-parameter
-Wunused-value
-Wunused-variable
-Wunused(=all of the above)

Each of these has a corresponding negative form with "no-" inserted after the W which turns off the warning (in case it was turned on by -Wall, for example). Thus, in your case you should use

-Wno-unused-function

Of course this works for the whole code, not just compile-time asserts. For function-specific behaviour, have a look at Function attributes.

cc1: warnings being treated as errors
somefile.c:200: error: the frame size of 1032 bytes is larger than 1024 bytes

The line number points to the closing brace of a c function that has a signature like this:

void trace(SomeEnum1 p1,SomeEnum2 p2,char* format,...){char strBuffer[1024];...

The function prints some stuff into the buffer.

error: implicit declaration of function ‘daemonize’ [-Werror=implicit-function-declaration]

编译内核时出现“make CONFIG_DEBUG_SECTION_MISMATCH=y” 错误提示：

首先，我們去下載一份ldd3的配套源碼,下面是我分享的一份代碼，大家可以下載使用：http://yunpan.cn/lk/sV2ZrN6JFEKKW?sid=301

對源碼進行解壓，裏面會有好幾個目錄，我們現在要關心的就是scull這個目錄，下面的操作都會在這裏進行。

root@yafeng-VirtualBox:/examples# ls

the frame size of XXX bytes is larger than 1024 bytes

最近編譯時遇到的問題
找了好久
