            Bug ID: 30001
           Summary: Port to autoconf build system (maybe use sbrabec's
                    patch?)
           Product: bzip2
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: bzip2
          Assignee: nobody at sourceware dot org
          Reporter: slyich at gmail dot com
                CC: bzip2-devel at sourceware dot org
  Target Milestone: ---

To ease cross-compilation of bzip2 NixOS uses

   
https://ftp.suse.com/pub/people/sbrabec/bzip2/for_downstream/bzip2-1.0.6.2-autoconfiscated.patch
version of autoconf build system for bzip2.

WDYT of merging it upstream in some form?

Currently NixOS generates ./configure using autoconf and automake. NixOS would
prefer using autoconf-based upstream bzip2 release tarball without a dependency
on these development tools.

Thanks!

In general my understanding is that autoconfiscation patch you linked was
explicitly rejected several times due to the "Incompatible changes" section.

My patch series solves this problem and a number of other problems. It should
also still work fine with cross-compilation, just specify `./configure
--host=<triplet>` and it will set up e.g. `$CC` correctly.

One comment... To cross-compile, you should specify both --build and --host.
--build is easy. config.guess gives that triplet:

   $ find /usr/share -name config.guess
   ...
   /usr/share/autoconf/build-aux/config.guess

   $ /usr/share/autoconf/build-aux/config.guess
   x86_64-pc-linux-gnu

--host is the trickier one. There is no list of cross-compile triplets.
