<p class="MsoPlainText">Thank you, Stefan. <o:p></o:p></p>
<p class="MsoPlainText">I resolved the problem with copying the CPLEX library and include directory into SCIP directory.
<o:p></o:p></p>
<p class="MsoPlainText">But I need to ask another fundamental installation question.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I want to build SCIPoptsuite linking Cplex as LP solver with CMake.
<o:p></o:p></p>
<p class="MsoPlainText">(I intend to use SCIP Python interface, pyscipopt. The website said Makefile system is not compatible with PySCIPOPT.
<o:p></o:p></p>
<p class="MsoPlainText"><a href="https://github.com/SCIP-Interfaces/PySCIPOpt/blob/master/INSTALL.md">https://github.com/SCIP-Interfaces/PySCIPOpt/blob/master/INSTALL.md</a> )<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">From other mails in this archives, I found you suggested compiling it under MinGW, MSys, or MSys2 to install on Windows, which is Makefile system. Given these conditions and answers from this archive, I have a few question about installation
on Windows.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">1) Can I install SCIPoptsuite with lpx=cpx using CMake On Window? If not, I would find a Linux server without wasting more time on it.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">2) Can I use pre-built SCIPoptsuite and set Cplex as LPsolver?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">3) I actually tried to install it with CMake, but since I wanted to make it as simple as possible, I set the most parameters as off besides SCIP.
<o:p></o:p></p>
<p class="MsoPlainText">( cmake -Bbuild -H. -DZLIB=off -DREADLINE=off -DZIMPL=off -DGMP=off -DLPS=cpx -DSOPLEX=off -DGCG = off) and added the CPLEX_INCLUDE path and CPLEX_LIBRARY path ( copied the file and paste it into SCIP directory and use those path).<o:p></o:p></p>
<p class="MsoPlainText">Then, I got a bunch of unresolved external symbol error such as following error from the Visual studio.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Severity Code Description Project File Line Suppression State<o:p></o:p></p>
<p class="MsoPlainText">Error LNK2019 unresolved external symbol __imp__CPXaddcols@44 referenced in function _SCIPlpiAddCols scip C:\Program Files\scipoptsuite-7.0.0\build\scip\src\lpi_cpx.obj 1
<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">It seems like it also needs cplex.dll as well as cplex.lib to link them. I tried to add it to Debug folder inside the build directory, but it still has an error.<o:p></o:p></p>
<p class="MsoPlainText">I would appreciate any help.<o:p></o:p></p>
<p class="MsoPlainText">Thank you<o:p></o:p></p>

<p class="MsoPlainText">Hi,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">that paragraph in "Remarks on Installing under Windows using MinGW"
<o:p></o:p></p>
<p class="MsoPlainText">probably refers to a pretty old MinGW version. It was untouched since 2009.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">SCIP tries to create a softlink lib/include/cpxinc that points to C:/Program Files/IBM/ILOG/CPLEX_Studio129/cplex/include/ilcplex/. This never worked reliably for me. Try to just copy the directory C:/Program Files/IBM/ILOG/CPLEX_Studio129/cplex/include/ilcplex/
to lib/include/cpxinc instead.<o:p></o:p></p>
