I'm trying to call bak from Fortran (Visual Fortran) to Visual Basic (VB). Before I added the callback code, my Fortran code compiled and linked without a problem. I list the modifications I have introduced below. But here is the error message I get in the linking process:
" Linking...
LINK : fatal error LNK1181: cannot open input file "imsl.lib"
Error executing link.exe.
Memfor.dll - 1 error(s), 1 warning(s)"
If I remove "imsl.lib" from Project/Settings.../Link/Object/library module, I still get an error message - now over some other object.
Here is the basis for how I am trying to achieve callback.
In VB:
* I have defined a "callback"er function in a global module of VB.
* My call to Fortran has been expanded with one additional argument:
call Fortranroutine(T, AddressOf callback)
In Fortran:
* I have added 4 bytes in the number of argument bytes of the *.def file.
* The Fortranroutine code looks as follows:
subroutine Fortranroutine(T, VBcallback)
real T
integer i
integer, external :: VBcallback
i = VBcallback(T)
....
Question:
--Does anyone see a problem with the way I have tried to organize the callback?
-- Does anyone see what is the problem with the linking process?
Thanks!
