Hello!
I have a problem in IDL. I try to call a C-Prog in IDL. I use IDL6.0
under win2000. I will call the C-Prog with the IDL function
"call_external". I write 2 short test-programms to see the handling of
the function.
my C-Prog "probiere.c":
#include <stdio.h>
#include <stdlib.h>
int probiere( void ){
int i, j;
j = 4711;
printf("Hello World\n");
i = getchar();
return j;
}
I compile this file with the Borland c++ compiler to create a
'probiere.dll'.
I do this like: "bcc32 -WD probiere.c"
my IDL-Prog "c_call_from_idl.pro"
pro c_call_from_idl
print, 'vor c aufruf'
result = call_external('C:\sgossen\idl\igor\c-prog\probiere.dll','pro biere')
print, 'nach c aufruf'
print, 'result: ', result
help, result
end
Executing this file I get following error-message:
% CALL_EXTERNAL: Error loading sharable executable.
Symbol: probiere, File =
C:\sgossen\idl\igor\c-prog\probiere.dll
ERROR_PROC_NOT_FOUND
I don't really know where the error could be. The path of the
.dll-file is still correct.
Can you help me with my problem?
Thank you!
