[Casa-framework] casapy - undefined symbol

[Tim Cornwell]

I'm trying to run casapy on a Mac. After many struggles and lots of  
help from Boyd and Wes, I have everything compiled. However, I get  
the following messages.

nattai:/opt/casa/code/tools/implement/simulator root# casapy
casapy(14757) malloc: *** error for object 0x1836400: incorrect  
checksum for freed object - object was probably modified after being  
freed, break at szone_error to debug
casapy(14757) malloc: *** set a breakpoint in szone_error to debug
Traceback (most recent call last):
   File "/opt/casa/darwin/python/2.5//casapy.py", line 2, in <module>

   Referenced from: /opt/casa/darwin/lib/libtools.dylib.19.1488

I had a look in tools/simulator and the following does exist:

bool
simulator::observe(const std::string& sourcename, const std::string&  
spwname, const Quantity& starttime, const Quantity& stoptime)
{


Does anyone have any suggestions?

Thanks,

Tim
