#include一个二进制文件？ [英] #include a binary file?
问题描述
大家好，
我有一种情况需要生成一个新的二进制文件
只需更改几个字节在预先存在的
主模板文件中放置。
我可以逐字节打开并读取原始文件并将其吐出来
a新文件，只需更改相应的字节。但是由于这些
文件只有大约1k字节长，我想将这些字节直接包含在我的代码中，例如：作为静态数组。这将创建一个更清洁的情况，因为我不必知道原始
文件的位置，担心它被删除/移动/修改等等。
代码生成会更容易一些（不是很难）。
然而我不知道你如何将标签附加到
顶部，确保编译器没有重新排列任何字节，
当然，如何使编译器将其视为一块
字面字节被认为是静态数据而不是内联汇编
或者其他什么。
假设该文件包含4字节，FF FD 45 34
我想要的东西相当于：
char template_file [] = {0xFF，0xFD，0X45 ，0x34};
我使用的是Visual C ++版本6.
感谢任何提示。
Garyescribió：
让我们说文件包含4个字节，FF FD 45 34
我想要的东西相当于：
char template_file [ ] = {0xFF，0xFD，0X45,0x34};
为什么等效？创造这个。
问候。

当我遇到这个问题时，我解决了它通过添加一个汇编模块，我用
使用Nasm来组装
（它有一个名为incbin的指令左右）这样的方法。
然后可以将输出文件与Visual C ++目标文件链接。

感谢您的任何提示。
只需编写一个简单的实用程序来读取二进制文件并生成一个。 cpp
带有上述定义的
文件，然后在你的程序中链接或包含在
中。您可以将程序作为预构建步骤运行，也可以创建
a构建依赖项，这样就不会不必要地运行。

Hi all,
I have a situation where I need to generate a new binary file which
just changes a couple of bytes in a couple of places in a pre-existing
master template file.
I can open and read the original file byte by byte and spew it out to
a new file, just changing the appropriate bytes. However since these
files are only about 1k bytes long, I''d like to include those bytes
directly into my code, e.g. as a static array. This would create a
cleaner situation in that I wouldn''t have to know where the original
file was, worry about it getting deleted/moved/modified etc. And the
code generation would be a little easier (not that it is hard).
However I am unclear how you would go about attaching a label to the
top of it, making sure that the compiler didn''t rearrange any bytes,
and of course, how to make the compiler treat this as just a block of
literal bytes to be considered static data rather than inline assembly
or whatever.
Let''s say the file contains 4 bytes, FF FD 45 34
I want something that creates the equivalent of:
char template_file[] = {0xFF, 0xFD, 0X45, 0x34 };
I am using Visual C++ version 6.
Thanks for any hints.

Why the equivalent? Create just that.
Regards.

When I had this problem, I solved it by adding an assembly module that I
used Nasm to assemble
(it has a directive called incbin or something like that).
The output file can then be linked with the Visual C++ object files.
You can get nasm from http://sourceforge.net/projects/nasm.

Just write a simple utility that reads the binary file and generates a .cpp
file with the above definition in it, and then link with or include this in
your program. You can run the program as a pre-build step, ore maybe create
a build dependency so it is not run unnecessarily.
