Hi,
 
   I was trying to install PYTHON1.6.1 on a sparc
 solaris7 computer with support for thread and bsddb
 module (I used the BerkeleyDB3.0).
   I dont have GCC on this machine so I used CC (I add
 the  -mt and -D_REENTRANT).
  
   The compilation is ok except at the end when it
 tried to build the python executable. I received a
 message about unknow function Py_main.
 
   Is anybody knowing this problem (and the way to
 correct it) ?
 
  Best regards.

Py_Main should be defined in main.o. Please to "ar tv
libpython1.6.a" to verify that main.o is really there, do
"nm main.o" to verify that it really provides Py_Main.
If not, please try wether rebuilding from a clean tree helps
(or correct the error manually, e.g. by adding main.o to
libpython1.6.a)

In any case,Python 1.6 is not maintained anymore: so if
there is a bug in it, it won't be fixed. Please try to
install Python 2.0 instead, or go back to 1.5.2, which is
known to work flawless on Solaris.
