Hi,
I tried to build libunwind from scratch and ran into a couple of small
issues:
1. There is no "autogen.sh" script to bootstrap the auto-tools. While I
understands this is not strictly necessary, it's a nice addition and
something found in pretty much any other project.
2. The man pages are re-generated uncondionnaly and require latex2man,
but the configure script does not check for latex2man, so if one doesn't
have latex2man installed on the host, the build fails.
Attached is a patch to address these two little issue:
1. Add the autogen.sh script (trivial)
2. Ad a new configure option "--enable-documentation" enabled by default
(to mimic current behavior) and check for latex2man presence only if
that option is enabled. If not, the man pages are not re-generated.
HTH,
Cheers,
Olivier

Subject: [PATCH] Fix build from scratch
- Add autogen.sh to bootstrap autotools generation
- Make generation of man pages optional, and check for
availibity of latex2man if documentation is requested.
