I'll see if it's actually the C-part that's causing problems, but I worked
it around by adding:
PyRun_SimpleStr ing("import sys\nsys.path.i nsert(0,'')");
right after the Py_Initialize() .
Works ok. Guess I'm "allowed" to do that(?)
IMLK (In My Limited Knowledge) that seems okay, but it also feels a bit
ham-handed. try this snippet:
---untested code---
#include <string.h>
#include <stdlib.h>
/* prototyping may not be neccessary... dunno...*/
extern char *getenv(const char *name);
extern char *setenv(const char *name, const char *value, int overwrite);
/* comment them out if gcc complains about redeclarations. */
/* append something to pythonpath */
/* returns 0 on failure, 1 on creation of the env variable and 2 on an append
oh, and -1 in cases of catastrophic miscompilation */
int myPyPathAppend( char *extrapath)
{
char *buffer = NULL;
/* size to taste... You should do this dynamically to avoid future buffer overrun attacks*/
char eventual_path[1024] = { 0 };
/* take note: after getenv, buffer points to an external constant character buffer.
do NOT try to modify it directly. use strcpy(char *dest, char *src)
(he says knowingly... is she into photography mate?)
*/
if( (buffer = getenv("PYTHONP ATH")) == NULL )
{
/* we're here because PYTHONPATH is not already part of the environment. */
setenv("PYTHONP ATH", extrapath, 1); /* the last argument makes sure that we create the env var*/
/* did it go happen .. you should check this more rigorously*/
if( (buffer = getenv("PYTHONP ATH")) == NULL)
{
/* we failed... abend. */
return 0;
}
else
{
/* success! cheers! */
return 1;
}
return -1; /* dead code... should never reach here */
}
else
{
/* PYTHONPATH already exists. append ';', then our new path and update it. */
/* find the "=" in the buffer...
from string.h
extern char *strstr (__const char *__haystack, __const char *__needle)
there's a better way to do this, but I can't recall the function off the top of my head
*/
buffer = strstr(buffer, "=") + 1; /* +1 because buffer points to the equals. we want the string starting after it. */
/* copy the old PYTHONPATH string */
strcpy(eventual _path, buffer);
strcat(eventual _path, ";");
strcat(eventual _path, extrapath);
setenv("PYTHONP ATH", extrapath, 1); /* the last argument makes sure that we create the env var*/
/* did it go happen .. you should check this more rigorously*/
if( (buffer = getenv("PYTHONP ATH")) == NULL)
{
/* we failed... abend. */
return 0;
}
else
{
/* success! cheers! */
return 2;
}
return -1; /* dead code... should never reach here */
}
else
{
/* PYTHONPATH already exists. append ';', then our new path and update it. */
/* find the "=" in the buffer...
from string.h
extern char *strstr (__const char *__haystack, __const char *__needle)

*/
buffer = strstr(buffer, "=") + 1; /* +1 because buffer points to the equals. we want the string starting after it. */
/* copy the old PYTHONPATH string */
strcpy(eventual _path, buffer);
strcat(eventual _path, ";");
strcat(eventual _path, extrapath);
setenv("PYTHONP ATH", extrapath, 1); /* the last argument makes sure that we create the env var*/
/* did it go happen .. you should check this more rigorously*/
if( (buffer = getenv("PYTHONP ATH")) == NULL)
{
/* we failed... abend. */
return 0;
}
else
{
/* success! cheers! */
return 2;
}
return -1; /* dead code... should never reach here */
}
return -1; /* deader code... should *really* never reach here */
}
---untested code---
I haven't tested, compiled or even read through this code.
I'm late for a party and still added comments
That means you get punctuation patrol :-P
Check the semicolons, check the braces
Hey, I hear that in some companies they call this teamwork methodology
"extreme-programming" We're buzzword compliant!
