calling C from IDL

description: 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! Sascha Gossen
