<p class="MsoNormal">Thanks for the libCoinUtils fix and the WSMP_FUNC suggestion!</p>
<p class="MsoNormal">Currently, for me none of the Cbc/Clp/Cgl Visual Studio projects build ‘out of the box’—without config.</p>

<p class="MsoNormal">For WSMP_FUNC, I compared the older stable Clp Visual Studio v10 project, and indeed all such special functions are by default Excluded from the project. I propose the same for the v16 project.</p>

<p class="MsoNormal">For libCoinUtils, and similar issue with the new xxxLIB_EXPORT, the Visual Studio projects can simply be the plain vanilla builds to work out of the box, without any external components. But for that the sections for xxLIB_EXPORT in the
relevant config_default.h and config_xxx_default.h need a minor fix: </p>

This might be fixed now.<br>

<br>
Then you should add a define for WSMP_FUNC according to the name <br>
mangling scheme that your Wsmp library uses.<br>
That is, if you don't have Wsmp, don't try to build ClpCholeskyWssmp.cpp.<br>
<br>

<br>
The main supported buildsystem for CoinUtils, Clp, Cbc, etc is the <br>
autotools-based system, which should work with MS compilers under MSys2 <br>
on Windows, too.<br>
This buildsystem has been updated in the master branches, that is, the <br>
current development versions of CoinUtils, Clp, Cbc, etc., recently, <br>
which also brought some changes to the code itself. This very likely <br>
broke these MSVS project files. Noone looked into fixing these so far.<br>
