使用 GCC 在可执行文件中嵌入资源

使用 bin2c/bin2h 实用程序将任何文件转换为字节数组 (在代码中嵌入图片，不使用资源部分或外部图片)

use a bin2c/bin2h utility to turn any file into an array of bytes (Embed image in code, without using resource section or external images)

更新:这里有一个更完整的例子，说明如何使用ld -r -b binary绑定到可执行文件中的数据:

Update: Here's a more complete example of how to use data bound into the executable using ld -r -b binary:

#include <stdio.h>

// a file named foo.bar with some example text is 'imported' into 
// an object file using the following command:
//
//      ld -r -b binary -o foo.bar.o foo.bar
//
// That creates an bject file named "foo.bar.o" with the following 
// symbols:
//
//      _binary_foo_bar_start
//      _binary_foo_bar_end
//      _binary_foo_bar_size
//
// Note that the symbols are addresses (so for example, to get the 
// size value, you have to get the address of the _binary_foo_bar_size
// symbol).
//
// In my example, foo.bar is a simple text file, and this program will
// dump the contents of that file which has been linked in by specifying
// foo.bar.o as an object file input to the linker when the progrma is built

extern char _binary_foo_bar_start[];
extern char _binary_foo_bar_end[];

int main(void)
{
    printf( "address of start: %p
", &_binary_foo_bar_start);
    printf( "address of end: %p
", &_binary_foo_bar_end);

    for (char* p = _binary_foo_bar_start; p != _binary_foo_bar_end; ++p) {
        putchar( *p);
    }

    return 0;
}

更新 2 - 获取资源大小:我无法正确读取 _binary_foo_bar_size.在运行时，gdb 通过使用 display (unsigned int)&_binary_foo_bar_size 向我显示文本资源的正确大小.但是将其分配给变量总是给出错误的值.我可以通过以下方式解决这个问题:

Update 2 - Getting the resource size: I could not read the _binary_foo_bar_size correctly. At runtime, gdb shows me the right size of the text resource by using display (unsigned int)&_binary_foo_bar_size. But assigning this to a variable gave always a wrong value. I could solve this issue the following way:

unsigned int iSize =  (unsigned int)(&_binary_foo_bar_end - &_binary_foo_bar_start)

这是一种解决方法，但效果很好，而且不太难看.

It is a workaround, but it works good and is not too ugly.
