Disable Binary stripping in rpmbuild

Stripping Binary files in rpmbuild

RedHat Package Manage
When we create an RPM using rpmbuild, the binary files are stripped. The intention is to reduce the file size, without affecting the functionality. This is the default setting, configured using the rpm macro__os_install_post.  
 
This blog entry talks about how to disable this option. 
 
This is done using the compression scripts, installed as part of rpm-build rpm.
The rpm macro __os_install_post is defined to execute these scripts. The scripts used to compress the binary file size are as follows.
$ rpm --showrc | grep -A 4 ': __os_install_post'
-14: __os_install_post  
    /usr/lib/rpm/brp-compress 
    /usr/lib/rpm/brp-strip 
    /usr/lib/rpm/brp-strip-static-archive 
    /usr/lib/rpm/brp-strip-comment-note

Recently, I had an uncommon requirement to disable this option. I do not want to reduce the file size of all files packaged in the rpm. This is achievable using any of 3 mechanisms.

  • Spec file
  • ~/.rpmmacros
  • /etc/rpm/macros
To prevent binary stripping for specific rpm, we could add following line at the top of any rpm spec file.
%global __os_install_post %{nil}
To prevent binary stripping for all rpms created by specific user, we could add following line in ~/.rpmmacros file:

%__os_install_post %{nil}

To prevent binary stripping for all rpms created by all users, we could add following line in /etc/rpm/macros file:

%__os_install_post %{nil}
