[Libunwind-devel] [PATCH] Fix build from scratch

[Olivier Fourdan]

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
