Thanks for your reply!
I tried that, but it still does not work. At first some more information on my build environment. I tried two PCs. Nr. 1 uses Win XP SP3 32bit with Visual Studio 2005 and the Intel Fortran 11.1 compiler. The second one is A Windows 7 64 bit with Visual Studio 2008 and the Intel Fortran 11.1 compiler. On both machines, I am able to compile A2AD and FAST without problems.
Now back to my problem with the DISCON.dll. I tried to compile it with
ifort /dll /winapp /libs:static DISCON.f90
and got the result ifort: warning #10153: option '/Qvc8' or higher used with '/ML[d]' is not supported
[...]
LINK : fatal error LNK1104: cannot open file 'LIBC.lib'
The first is a warning, not too important i guess, even though i specified none of these options. the second is fatal and causes termination.
I did some research and found that this seems to be a common problem with VS2005 (and higher?), and a solution would be to tell the fortran compiler that it does not require the LIBC.dll:
ifort /dll /libs:static /winapp DISCON.f90 /link /NODEFAULTLIB:libc
If I try this however, I get loads of errors:[...]
libifcore.lib(cvtas_a_to_s.obj) : error LNK2001: unresolved external symbol __fltused
libifcore.lib(cvtas_nan_t.obj) : error LNK2001: unresolved external symbol __fltused

[...]
LINK : error LNK2001: unresolved external symbol __load_config_used
DISCON.dll : fatal error LNK1120: 118 unresolved externals so I guess, that this library is indeed required.
I got these results on both machines, with the 64bit machine set to 32bit build environment variables. With 64bit settings on the Win7 machine, I get another error (ifort: error #10037: could not find ‘link’) but that is not of interest for me, because I want a 32bit dll file.
I will see If I can find it, thanks!
Could anyone of you, who successfully compiled the NREL 5MW onshore DISCON.f90 tell me about their system specification, and build command?
Thanks a lot,
