I am having trouble building csound 4.23.  In the CVS files i have
there is no Makefile.in for the utils2/export directory (which i am
sure i used to have) and in fact there is no Makefile.in in teh main
diretory either.  Also no configure 
  So how is one supposed to build it?

Hi John and all,

I thought the whole 4.23 tree was still using Makefile only and no 
autoconf scripts.  Did this change sometime?

Hi all,

I sent a few emails this morning but I don't think they got to the
server.  (BTW: is it ella or earth.mills.edu? apologies if everyone has
already read the following...)  I'm having problems with loading
--opcode-lib=Opcodes/spectra.so (similar errors with other opcode
libs).  I added and committed some code for error information using
dl_error() in Top/dl_opcodes.c in loadCsoundExternals().  I am receiving
this error when trying to load spectra.so:

A dynamic linking error occurred: (Opcodes/spectra.so: undefined symbol:
auxalloc)

The whole process ran as such:

[root@localhost csound5]# ./csound --opcode-lib=Opcodes/spectra.so

originally I had problems with not finding getstring, but now it's
auxalloc (for what reason it's changed I have no clue).  This happens
with other opcode-lib's as well.  

I tried it again with three opcode-libs and got:

I'm a bit stumped here and have been most of the night.  Been stepping
through with gdb and not much luck trying to figure out much.  Any
thoughts here appreciated!

thanks,
steven

Hi John,

Thanks for the changes.  I did get a bit further but encountered more
errors.  I decided I would go ahead and try loading all of the opcode
libs in the Opcodes directory to see the results.  I figured that for
each opcode lib that doesn't load it would give us error information. 
So, I made this command-line:


./csound
--opcode-lib=Opcodes/babo.so,Opcodes/bbcut.so,Opcodes/biquad.so,Opcodes/bowedbar.so,Opcodes/butter.so,Opcodes/clfilt.so,Opcodes/cross2.so,Opcodes/dam.so,Opcodes/filter.so,Opcodes/flanger.so,Opcodes/follow.so,Opcodes/grain4.so,Opcodes/grain.so,Opcodes/hrtferX.so,Opcodes/locsig.so,Opcodes/lowpassr.so,Opcodes/midiops2.so,Opcodes/midiops3.so,Opcodes/modal4.so,Opcodes/nlfilt.so,Opcodes/oscbnk.so,Opcodes/phisem.so,Opcodes/physmod.so,Opcodes/pitch.so,Opcodes/pluck.so,Opcodes/repluck.so,Opcodes/scansyn.so,Opcodes/scansynx.so,Opcodes/sfont.so,Opcodes/sndwarp.so,Opcodes/space.so,Opcodes/spat3d.so,Opcodes/spectra.so,Opcodes/ugensa.so,Opcodes/uggab.so,Opcodes/ugmoss.so,Opcodes/ugrw1.so,Opcodes/ugrw2.so,Opcodes/ugsc.so,Opcodes/wave-terrain.so test.csd

(I put it in a shell script, also attached)

And I got this:

[root@localhost csound5]# ./csound

So it looks like it failed to load babo gracefully, moved on to bbcut
which it loaded but then died on.  Running this with gdb, it dies on
line 312 of dl_opcodes.c:

        resetter = dlsym(handle, "RESET");


Going to sleep now, will try again in the morning.  

Thanks!
steven

That error message means that the function auxalloc is used in teh .so 
file but is not defined.  All functions used in any plugin must be in the 
global structure.  What you are suggesting is that you have found another 
function that is needed.  Will take a quick look.
==John

Try again; code adjusted.  There will be more of these
==John

Added die to the internal allowed calls.  Cannot see why dlsym on RESET 
should fail -- I would expect it to return NULL.  Anyway I have revised 
the code.  
  What would be useful is an attempt top load each plugin separately and 
then listing the undefined functions.   Then I could fix in one step.
==John

Running the test.sh without bbcut.so, I receive:

I can't find where it's dying with gdb, it seems to get through
csoundLoadExternals alright (the "All loaded" message prints), but
before anything else happens in csoundCompile it segfaults.  

Thanks,
steven

Thanks; I will look at that tomorrow (Ta'iChi tonight)
