Re: GNU APL build system changes

[Chris Moller]

    Cool--I just wasn't sure how consistent you wanted
      the builds to be across download mechanisms.  It's awkward that
      git doesn't directly support a straight-forward version-number
      mechanism that could inherit SVN revision numbers--a ridiculous-number-of-digits SHA1 string isn't terribly
      convenient.

Hi Chris,

it is generally OK to get "*** current directory is not a svn checkout: keeping old buildtag"
if you fetch GNU APL with anything other than SVN, e.g. with git clone or by unpacking a tar
file. At least as long as you don't switch back-and-forth between SVN and git with the same
checkout directory.

However, the fallback file that was used below was incorrect because I had forgotten to "git add"
the buildtag.hh (typical mistake of SVN users where this is automatic). Therefore you got your own last
buildtag (1410M from the savannah SVN) instead of my last buildtag (17930).

This should be fixed now.

Best Regards,
Jürgen

I don't know if it's significant, but I used git clone to pull down the source code for 1449 and that results in a ./configure message of:

*** current directory is not a svn checkout: keeping old buildtag

and an `apl --version` of

BUILDTAG:

Hi,

as some of you have noticed, I made some changes to the GNU APL build system.

Some of these changes were simplifications of the build system (some automatically
generated .cc and .hh files like configure_args.cc are gone for good), while other changes
 were needed to support Autoconf VPATH builds. Also all files generated by ./configure
now stored in the top-level directory so that the subdirectory src (which is shared by all
VPATH builds) is no longer muddied with ./configure results.

The purpose of VPATH builds is to be able to build several ./configure variants in
parallel. Different VPATH builds are needed to discover build problems, in particular with
rarely used ./configure variants before these problems  are committed to the savannah
SVN server.

There could still be glitches in the new build structure, so please keep reporting
them.

SVN 1449.

Best Regards,
Jürgen
