Thank Amaury,you are right.
So python2.7 share library compile finished,and python2.7 works,and then
I write a test program,to test libpython2.7.so share library,but it dumped!
code:
-----------------------
#include <stdio.h>^M
#include "Python.h"^M
#include <dlfcn.h> ^M
^M
int main( int argc, char **argv )^M
{^M
Py_Initialize();
if(!Py_IsInitialized())
{
printf("py initialized fail!");
return -1;
}
void* handle = dlopen("/usr/local/lib/python2.6/lib-dynload/time.so", 2);
if (handle == NULL) {
const char *error = dlerror();
if (error == NULL)
error = "unknown dlopen() error";
printf("erro=%s\n",error);
return NULL;
}
if(!Py_IsInitialized())
{
printf("py initialized fail!");
return -1;
}
printf("hi,python!\n");
PyRun_SimpleString("from time import time,ctime\nprint 'Today
is',ctime(time())\n");
Py_Finalize();
}
----------------------------------------------------
This code can compile sucess,but run core dump:
ibm1:mmi>pytest
hi,python!
Fatal Python error: Interpreter not initialized (version mismatch?)

---------------------------------------
the line 38 in "modsupport.c":
if (!Py_IsInitialized())
Py_FatalError("Interpreter not initialized (version mismatch?)");
it looks like "Py_IsInitialized()" is false,but in my main(),the
"Py_IsInitialized()" return true.
