I have reinstalled from scratch the Debian system (having failed to
install gentoo as if failed to compile) and upgraded to stable/woody.
I also installed autoconf-2.59, automake-1.8.2 and libtools-1.5.2 from
the sources. 
  A completely new checkout of csound5 onto a clean disk.  Ran
autoreconf -i -f and waited.   Usual error messages followed by a exit
with error 1.
  No ./configure file has been made.

Thought that perhaps it was still using older versions of autogen etc
so deleted files from /usr/bin/auto* (must be a better way but have
not understood Debian yet) and redid the autoreconf.  this time
similar error messages but a ./configure built.

Ran it; strange that it cares whether I have g77 installed, and many
other irrelevant questions.  Finally after a long time built
makefiles.

make then failed as it could not find sndfile.h wanted by auxfd.c.  If
I do not have libsndfile installed why does it set _SNDFILE_ ?  Seems
like a bug to me.

Next stage; I installed sndfile libraries and now it complains that 
-falign-loops and -faligh-jumps are invalid options.  I thought the whole 
purpose of autoconf was to match options and compilers.  Resorting to 
editing teh Makefile I also notice that the option are repeated in a 
single flags line which seems odd to say the least.

So with hand modifications something is happening -- may take a while on 
this slow machine

Hi John,

I believe the configure.ac file in csound5 is not as polished as the one 
for csound4.  I noticed just now too that in the configure.ac in csound5 
the "$hosts" section doesn't include darwin, which was added to 
csound4's configure.ac.  Also, the check for gcc version is not there, 
but the configure flag for --with-gcc3 is there (which has been set to 
default to yes).  If you set that flag to no with "./configure 
--with-gcc3=no" that should get you "-malign-loops and -malign-jumps". 

I'll spend a little time today to try to start the migration of features 
from the csound4 configure.ac to the csound5 one.  I'm sure John R and 
Michael will be able to work out what I can not.

Thanks,
steven

Hi All,

I removed the --with-gcc3 option from the csound5 configure.ac and added 
the automatic version check from John Ramsdell's csound4 configure.ac. 

Regarding other aspects of the two files, from a quick glance the 
strategies for setting options looks to differ slightly, not too bad but 
enough to require some deeper investigating before integrating, as it 
also requires to check sources as some #define's were removed, renamed, 
added in csound4 to make that more consistent that might not have been 
done so in csound5.
