calling matlab from fortran

Don Bruce

I would greatly appreciate it if someone could help me work out a
problem I have when trying to call matlab from fortran. I am using
matlab 6.5.1 and CVF6.6.

When I am trying to execute the compiled program fengdemo.f I get the
following error message:

The procedure entry point ENGPUTVARIABLE@16 could not be located in
the dynamic link library libeng.dll.

I have included the libraries libmat.lib libeng.lib libmx.lib in the
object/libraries modules box under 'settings' -> 'links'.

Plus, I have created a link to the libraries in the tools -> options
-> directories -> libraries (library lifes option).

Is this the correct approach? If not, is there a better way.

Moreover, is anyone aware of relevant documentation. Many people seem
to have found sililar problems (especially related to the program
fengdemo.f).

Many thanks
Don

Check to see if an export entry for ENGPUTVARAIBLE is present in
libeng.def. It is not present for Matlab R12 but you mention that you're
using R13. Also, crosspost to comp.soft-sys.matlab.

The export entry for ENGPUTVARAIABLE is indeed present in libeng.def.
I have still had no luck. In fact now the error message I get is a
little different:

"The application has failed to start because libmx.dll was not found.
Reinstalling the application may fix this problem."

(I can't remember exactly what I changed because I have tried almost
everything).
I have have included a path to the directory containing the 'lost' dll
(using tools->options->executables), but it doesnt seem to find it.

No can do -- that setting affects only tools ran from VS "Tools" menu.
Instead, you should append that directory to your PATH environment variable
(My computer->Properties->Advanced->Environment variables).

Doesn't MATLAB setup do it for you? Or it got screwed in the process?

This works:

1. Make a CVF console app using fengdemo.f90 (free form and change all the
C's to ! in the MATLAB .f file).
2. -> Project Settings/Link/General make sure that the Object/library
modules: reads
libmatpm.lib libmmfile.lib libmatlb.lib libmx.lib libmat.lib libeng.lib
kernel32.lib ...
3. ditto for Project Settings/Link/Input and that the Additional library
paths: reads
C:\matlabR12\extern\lib\win32,C:\matlabR
12\extern\lib\win32\microsoft\msvc6
0
4. You don't need to fiddle with anything else. Rebuild and execute.

PS

Note that instead of specifying the lib paths in Project
Settings/Link/Input/Additional library, ->Tools/Options/Directories/Library
files and create entries for

C:\matlabR12\extern\lib\win32

and

C:\matlabR12\extern\lib\win32\microsoft\
msvc6

I have checked and the path is already defined correctly in
environment variable PATH.

In any case I now have a quick and dirty solution to the problem: copy
everything from the relevant directory (in my case
C:\MATLAB6p5p1\bin\win32) into the directory where the executable is
located (I had already tried copying only the relevant files but it
appears to need more...).

Nevertheless, this is still unsatifying, and I would be interested to
hear if anyone has the correct solution.
Thanks
Don

PPS

I've just checked: the CVF project successfully migrates to IVF 8 but you
must append the ..\lib\.. entries to -> Tools/Options/Intel/Libraries, the
CVF migration wizard does the rest.
