Subject: [PATCH bzip2 1/6] install relative symlinks
Date: Thu, 02 Jun 2022 23:45:49 -0400	[thread overview]
Message-ID: <> (raw)

From: Eli Schwartz <>

During `make install`, symlinks for command aliases are created which
embed an absolute path to the installed location of the real file. This
causes issues with relocation, for example when packaging for distros.

Use symlinks that search for a file in the same directory as the
symlink, instead. This is guaranteed to have the same results, except
more accurate.
