CentOS 5.5 - symbolic link creation into RPM spec file
提问by Dima
I need to create the following symbolic links into RPM file
我需要在 RPM 文件中创建以下符号链接
/bin/ln -sf libcrypto.so.0.9.8e /lib/libcrypto.so.0.9.8
/bin/ln -sf libssl.so.0.9.8e /lib/libssl.so.0.9.8
In my RPM spec file:
在我的 RPM 规范文件中：
%files
%defattr(-,root,root)
/lib/libcrypto.so.0.9.8
/lib/libssl.so.0.9.8
<other files...>
%install
/bin/ln -sf libcrypto.so.0.9.8e /lib/libcrypto.so.0.9.8
/bin/ln -sf libssl.so.0.9.8e /lib/libssl.so.0.9.8
The /lib/libcrypto.so.0.9.8e and /lib/libssl.so.0.9.8e are exists on my PC, but when I'm trying to install my RPM, I got an error:
我的 PC 上存在 /lib/libcrypto.so.0.9.8e 和 /lib/libssl.so.0.9.8e，但是当我尝试安装 RPM 时，出现错误：
libcrypto.so.0.9.8 is needed by my-test-rpm-1.el5.i686
libssl.so.0.9.8 is needed by my-test-rpm-1.el5.i686
What wrong? What I need to do in order to create symbolic links as part of the RPM installation?
什么错？我需要做什么才能创建符号链接作为 RPM 安装的一部分？
Thanks
谢谢

As workaround I disabled automatic dependency processing by adding:
作为解决方法，我通过添加以下内容禁用了自动依赖处理：
AutoReqProv: no
to my spec file. I'm still looking for the real solution.
到我的规范文件。我仍在寻找真正的解决方案。

You need to run ldconfig in the %post part of the spec file:
您需要在规范文件的 %post 部分运行 ldconfig：
%post
umask 007
/sbin/ldconfig > /dev/null 2>&1
%postun
umask 007
/sbin/ldconfig > /dev/null 2>&1
should do it.
应该这样做。

1) Just for symlinks you don't need to call ldconfig at post stage.
1）仅对于符号链接，您不需要在后期调用 ldconfig 。
2) As already mentioned by ldav1s: Be sure that your files are listed in %files section.
2) 正如 ldav1s 已经提到的：确保您的文件列在 %files 部分。
3) Once again: Be sure that your files are listed - especiallyif you use something like
3）再次：确保您的文件已列出 -特别是如果您使用类似
%define _unpackaged_files_terminate_build 0
RHEL rpmbuild terminates with an error if files are found in buildroot which are not listed in %files section. With this define you can switch the behaviour/error off but you should exactly know what you are actually doing. If you use this line you should remove it from your spec file.
如果在 buildroot 中找到未在 %files 部分中列出的文件，则 RHEL rpmbuild 会因错误而终止。使用此定义，您可以关闭行为/错误，但您应该确切地知道自己在做什么。如果你使用这一行，你应该从你的规范文件中删除它。
4) Don't build the rpm package as user root. If you forget to use rpm_build_root you won't destroy your live system. Your example looks like it was taken from a spec file of Red Hat 4.2 of 1997. Since Red Hat 5 (not RHEL 5!) in 1997 the rpm/rpmbuild command knows the RPM_BUILD_ROOT definition. I guess that this is your problem: You don't use the buildroot but install directly into the root FS and run rpmbuild as user root.
4）不要以root用户身份构建rpm包。如果您忘记使用 rpm_build_root，您将不会破坏您的实时系统。您的示例看起来像是取自 1997 年 Red Hat 4.2 的规范文件。自 1997 年的 Red Hat 5（不是 RHEL 5！）以来，rpm/rpmbuild 命令知道 RPM_BUILD_ROOT 定义。我猜这是您的问题：您不使用 buildroot，而是直接安装到 root FS 并以 root 用户身份运行 rpmbuild。
Given your example it should be changed to:
鉴于您的示例，它应该更改为：
%install
/bin/ln -sf libcrypto.so.0.9.8e $RPM_BUILD_ROOT/lib/libcrypto.so.0.9.8
/bin/ln -sf libssl.so.0.9.8e $RPM_BUILD_ROOT/lib/libssl.so.0.9.8
Using buildroot is described in RPM docs.
RPM 文档中描述了使用 buildroot 。

The best way to do this is by preventing the symlinks you created from being scanned by the automatic depends & requires generators:
最好的方法是防止您创建的符号链接被自动依赖和需要生成器扫描：
%filter_provides_in libcrypto.so.0.9.8e
%filter_provides_in libssl.so.0.9.8e
%filter_requires_in libcrypto.so.0.9.8e
%filter_requires_in libssl.so.0.9.8e
%filter_setup
