在链接描述文件中提取存档文件 [英] Extracting archive file in linker script

问题描述

我正在尝试解决以下问题:

I am trying to deal with a problem like the following one:

假设我有一个库libxyz.a，创建自:

Assume that I have a library libxyz.a created from:

/* main.c */
int main(void)
{
  int a;
}

使用以下文件进行编译和存档:

compiled and archived with:

gcc -c main.c -o abc.o && ar cr libxyz.a abc.o

我必须如何编写链接程序脚本才能将abc.o准确放置在预期位置?

How do I have to write linker script in order to put abc.o exactly where it is expected to be?

我试图以这种方式处理它:

I was trying to handle it in such way:

/* script.ld */
SEARCH_DIR(.)
INPUT(-lxyz)
SECTIONS
{
   .text : { xyz:abc(.text) }
   .data : { xyz:abc(.data) }
   .bss  : { xyz:abc(.bss) }
}

但运行后:

ld -T script.ld

我得到:

ld: cannot find xyz:abc

我在论坛的链接器文件中找不到提取存档的任何示例.我唯一发现的是链接器的文档，该文档仅包含有关 archive:file 构造的信息.

I couldn't find any example of extracting archives in linker files on forums. The only thing I have found was the linker's documentation, which only contains information about archive:file construction.

推荐答案

今天只需要处理相同的问题，因此如果有人碰到这个问题:缺少某些文件扩展名.像这样的东西很好:

Just had to deal with same problem today, so if someone else bumps into this question: some file extensions are missing. Something like works fine:

SECTIONS
{
   .text : { libxyz.a:abc.o(.text) }
   .data : { libxyz.a:abc.o(.data) }
   .bss  : { libxyz.a:abc.o(.bss) }
}

还需要处理路径(如果库实际上在/libxyz.a中).

One also needs to deal with paths (if library is actually somewhere/libxyz.a).
