Pre-built binaries for Visual Studio C++

[UyenAtKite]

I’m new here and I kindly ask for help. We’re looking for pre-built binaries for a C++ project in Visual Studio, and I can’t find where to download them

See https://github.com/ERGO-Code/HiGHS#precompiled-binaries

Ah, I thought these links included libraries, not just executables. Perhaps @galabovaa can advise you

[galabovaa]

I thought they included libraries as well, perhaps @odow can confirm that they are not?

@UyenAtKite Do you use vcpkg? HiGHS can be installed via vckpg to build the dll and lib files for Visual Studio

[UyenAtKite]

@galabovaa Thank you. I am here a few days, not yet heard about vcpkg.

I think we removed the shared libraries from HiGHSStatic to reduce file sizes because people downloading the binaries should probably just care about the executable.

If you're compiling a C++ library, you must be familiar with compilers etc; just compile HiGHS yourself. It has no dependencies.

Thank you very much!

Why would that be the case? Although I happen to have cmake and a C++ compiler installed, I'm a C# developer so it's kind of a coincidence that I'm able to compile it. More importantly, we need both Windows and Linux dll/so, and when I follow the instructions I see when I click the Download button on the home page, I get neither a dll nor an so, only an exe.

This is how I build HiGHS with Microsoft visual studio:

git clone https://github.com/ERGO-Code/HiGHS.git
cd HiGHS
md build
cd build
cmake -DBUILD_SHARED_LIBS=ON ..
cmake --build . --config Release

This will generate under Release\bin the following files:
highs.lib
highs.dll
highs.exe

I also noted that you can find highs.dll here: https://www.nuget.org/packages/Highs.Native
Choose download package.
That will download a file with extension .nuget
Rename that extension to .zip
Open the zip file with your favourite zip program
under runtimes\win-x64\native you can find highs.dll

Thank you very much!

Thank you all for your help. I tried my first example for MIP in HIGHS. The codes were generated by Copilot with addColumns, addRows, changeObjectiveSense and run() but getModelStatus() returns HighsModelStatus::kNotset. I suppose some initialization was omitted. Can you give some advice?

This should be enough to build a complete model. What return codes do you get from addColumns, addRows, changeObjectiveSense and run()? Do you have any logging?

Take a look at https://github.com/peno64/HiGHStest/blob/main/call_highs_from_c.cpp
I compiled some examples there. See https://github.com/peno64/HiGHStest for the full visual studio project.
