Hi,
I've just starting out embedding Python in C and get the following error
when I try and import a module that in turn imports the math module.
ImportError: /usr/lib/python2.4/lib-dynload/math.so: undefined symbol:
PyExc_FloatingPointError
The module is as follows:
# begin script.py
import math
def fn(i):
print "i is %d" % i
# end script.py
and the C code is :
// start main.c
#include
int main(int argc, char *argv[]) {
PyObject *mymod, *fn, *strargs;
Py_Initialize();
mymod = PyImport_ImportModule("script");
if(mymod == NULL) {
PyErr_Print();
exit(1);
}
fn = PyObject_GetAttrString(mymod, "fn");
if(fn == NULL) {
PyErr_Print();
exit(1) ;
}
strargs = Py_BuildValue("(i)", 0);
PyEval_CallObject(fn, strargs);
Py_Finalize();
return 0;
}
// end main.c
Testing script.py by running python and importing the module works fine.
Commenting out the import math statement and import other modules (sys,
string etc) work fine.
The C program is being built like so:
gcc main.c -c -I-I/usr/include -I/usr/include -I/usr/include/python2.4
-I/usr/include/python2.4 -DNDEBUG -g -O3 -Wall -Wstrict-prototypes
gcc main.o -L/usr/lib -lpthread -ldl -lutil
-lm /usr/lib/python2.4/config/libpython2.4.a -o main
I've tried the above on two machines, one Debian stable and the other
Debian testing. Same results on both.
It's like I'm missing a library or something, any ideas ?
Cheers,
Simon Newton
