My PC is running WIN98 II (second edition) and the C and Fortran compiler
are that of Microsoft Develop Studio 4.0.
The problem seems to be not related to the compilers, since (as I wrote) I
get problems even calling a routine in a system library,
in fact I follow the example suggested by Ronn Kling to explain the DLM
utility "idl_tools.dlm":
print, EXTPROC_DEFINE("mysin","msvcrt.dll","sin","d(d)",/cdecl)
that should assign the function "sin" of the library "msvcrt.dll" to the IDL
function "mysin", the function should take a single argument as double and
return a double ... "d(d)". When I type the above command IDL seems to
accept the definition of the new function "mysin", but then when I try to
use "mysin" IDL crashes (idlde causes errors in IDL32.DLL and MFC42.DLL).
The same result is obtained compiling the SUM_ARRAY examples in the IDL
distrubution ...
There are a lot of useful Fortran libraries in the web, it is really sad
that I cannot use them with IDL !!!
have a nice day
