如何使二元与不同的分布兼容

How to make a binary compatible with different distributions

本文关键字：分布何使二更新时间：2023-10-16

我需要创建一个可执行的可执行文件，该可执行文件可与尽可能多的分布一起使用。我读了很多有关此信息的信息，发现有两种方法：静态链接和动态链接。第一个解决方案避免带来可执行的库，但许可证存在一些问题。第二个解决方案看起来越适合。通过动态链接，链接器将添加到可执行的ELF标题中，在执行二进制文件之前，所有所需的库中的所有参考都会加载这些库。

命令readelf -d <binary>显示所需的库：

Dynamic section at offset 0x149d80 contains 33 entries:

现在，我已经使用了链接器的选项来设置rpath -wl，-rpath， $$ oint/lib（http://en.wikipedia.org/wiki/rpath），因此在执行链接器之前，作为第一条路径。如果未设置dt_runpath（https://wiki.debian.org/rpathissue），则是正确的。在我的Ubuntu 12.04 64位上，如果我使用LDD检查，这是正确的所有库指向正确的路径。在不存在OpenCV库的Debian 7 64位，LDD返回

因此，是否可以获得仅取决于$ onect/lib库的可执行文件？我用Ubuntu编译了ubuntu 12.04 64位，但是如果我尝试在debian 7 64位执行，我会得到链接器LD-Linux-x86-64.so.2的细分故障，而在OpenSuse 12.3 64位，我得到了

二进制中的二进制/home/user/。还有其他解决方案可以分发无源代码的二进制问题吗？

yikes！这是依赖性的惊人数量！您将在各种分布中使所有这些依赖性都可以正常工作遇到很大的困难，这尤其是因为您可能严格依赖于特定版本，而这些版本中的少数版本（即。至少您可能只支持运送相同主要版本的发行版）。

正如您指出的那样，您应该永远不会创建一个完全静态的二进制（在非常具体的情况下才有用，因为静态编译的二进制是最小的便携式）。规则：切勿在libc中静态链接（如果这样做，则禁止致电dlopen）。允许您静态地链接libstdc ，这样做可以使您在更广泛的发行版中兼容，而牺牲了轻微的二进制尺寸增加。libm，libpthread基本上与libc相同，而古老的图书馆则是安全的，因为它们的ABI非常稳定。

在其余部分中，您需要将依赖项的树分开，并在最差的运行时间依赖关系中尝试静态链接，并记住您也必须在他们的依赖项中链接！因此，如果您发现必须在libavcodec上进行静态链接，那么您很可能也需要运送libspeex（除非它具有非常稳定的ABI，否则我尤其不知道该库）。

关于Debian 7 Libc问题：这可能是您要解决的问题中最简单的问题。您只需要编译要支持的最古老的发行版即可。如果您在最近的Ubuntu或Suse版本中编译，那么您将获得比Debian 7船更依赖GLIBC的依赖性。在较旧的机器上进行编译会很好（它将在较新的发行版上运行）。
