 Hi everyone,

I get the error: 'DLL load failed' when loading numpy in embedded python. I could not find a solution in the archive. Any help appreciated.

Could you get a more detailed log (looking into one of myriad logging system in windows) ? It should say why the dll fails loading (missing function, file not found, etc...). cheers, David

I have written a test as follows (borrowed from an other post): #include<stdlib.h> #include<stdio.h> #include<Python.h>

int load(){ PyObject *errobj, *errdata, *errtraceback; char* code = "import numpy\n"; Py_Initialize(); PyObject *m = PyImport_AddModule("__main__"); PyObject* d = PyModule_GetDict( m ); PyObject * resu = PyRun_String( code, Py_file_input, d, d); PyErr_Fetch (&errobj,&errdata,&errtraceback); if (errdata != NULL){ PyObject *s = PyObject_Str(errdata); char * c = PyString_AS_STRING(s); printf("%s\n",c); Py_DECREF(s); }else{ printf("no errors.\n"); } Py_XDECREF(errobj); Py_XDECREF(errdata); Py_XDECREF(errtraceback); Py_Finalize(); return 0; }

int main(int argc, char **argv){ load(); return 0; }

this is build using: gcc -I/openSource/python26/include -ggdb -c t.c -oc.o -Wall gcc c.o C:\openSource\python26\libs\libpython26.a -otest.exe -Wall

configuration is: windows vista mingw gcc 4.5.0 python 2.6 numpy 1.5

Your test program worked for me. Try opening the file test.exe with Dependecy Walker <http://www.dependencywalker.com/> and see which DLLs are found or missing. Christoph

For the record I intalled python 2.6.6 instead of an old 2.6.1 I had and it works Regards -- Jean-François MAUREL
