Link error in MS Visual Studio 2022

[Felipe Rodriguez]

Hello Dislin users,

I'm trying to use Dislin with MS Visual Studio 2022 for C++ and get the following link errors:

I followed the instructions provided in the FAQ section ("How can I use DISLIN with Microsoft Visual Studio C++ 2019/2022 ? "). Furthermore, when adding one of the C examples ("exa_c.c") from the folder C:\dislin\examples to an empty project then it works. It also works when for example copying the "Demonstration of CURVE / C", and add the file to the project.

But it doesn't work when I add to the project a C++ example ("exa_cpp.cpp") from the C:\dislin folder. It doesn't work either if I copy the C++ code example from "Demonstration of CURVE / C++" and then add this file to an empty project.

Any help is really appreciated.

Thanks.

Felipe

Dear Felipe,

for linking the example exa_cpp.cpp with Dislin you have to link with the Dislin library discpp.lib instead

of disvc.lib. The library is compiled for Release x64 and the multithread static runtime library (/MT).

With best regards,

Helmut

[Felipe Rodriguez]

Hi Helmut,

Thanks for your reply. I have already added the "discpp.lib" in the Linker input:

Also, the other changes have already been done, but the linker issue persists.

Yes, you are still in Debug and not in Release mode.

With best regards,

Helmut

[Helmut Michels]

Hi,

compiling and linking in Debug mode seems to work if you use the runtime library

LIBCMTD.lib (/MTd). Defaults libraries should be ignored in the linker settings for

suppressing some warnings.

With best regards,

Helmut

[Felipe Rodriguez]

Hi Helmut,

Thank you very much! Now it works in "Release" mode.

One question, I'm not experienced with linking, but cannot find the LIBCMTD.libfile,

where is it located?

Br,

Felipe

Hi Felipe,

you can select it in the Configuration Properties -> C/C++ > Code Generation property page of your

project.

With best regards,

[Felipe Rodriguez]

Hi Helmut,

Yes, now it works in DEBUG mode.

Thanks!
