Sorry for dragging up an old email, but I had this exact same problem trying
to compile on OSX 10.6. The items are clearly defined in lines 74& 75 of
schrodecoder.c and they make it into the object file
libschroedinger_1.0_la-schrodecoder.o
However, it appears that this object file is never included? By reversing it
and making the defines in schro.c, and referencing it in schrodecoder.c,
resolved the compile problem. [Leo - NO_PREFIX is not used anywhere in the
source, so I don't see how defining it would help, and it doesn't. Maybe
you where thinking of the gcc flag that turns off the appending of the leading
underscore?]
After fixing this, I get another similar problem. Actually, a whole host of
missing defines. Basically every _orc_code_orc_* defined in tmp-orc.c is not
found when trying to link upsample_speed. I see 2 tmp-orc.c files, one in
schroedinger, and the other in testsuite/perf. The second one doesn't appear
to get compiled.

So, what could be going wrong? Did you get any further George?
To many unfamiliar trees for me to find the rotten one easily...
I've posted my config.log, nm output from
schroedinger/.libs/libschroedinger-1.0.a, and the make output at:
http://www.whdt.net/config.log
http://www.whdt.net/nmoutput.txt
http://www.whdt.net/makeoutput.txt
Thanks for any hints you might have!
