Dear Nag,<br>
<br>
on the other hand, if you want to keep using the Makefile, compiling
SCIP should not be too hard either, you just need to set the correct
links.<br>
When SCIP asks you for the links, it should print some explanation
at the top of the prompt, which also gives some more details about
where your links should point to:<br>
<br>
<blockquote type="cite">* SCIP needs some softlinks to external
programs, in particular, LP-solvers.<br>
* Please insert the paths to the corresponding
directories/libraries below.<br>
* The links will be installed in the 'lib/include' and
'lib/static' directories.<br>
* For more information and if you experience problems see the
INSTALL file.<br>
<br>
-> "grbinc" is the path to the Gurobi "include" directory,
e.g., "<Gurobi-path>/include".<br>
-> "libgurobi.*" is the path to the Gurobi library, e.g.,
"<Gurobi-path>/lib/libgurobi.so"</blockquote>
<br>
Thus, you set the grbinc link correctly, but the
libgurobi.darwin.x86_64.gnu.so link should point directly to the
shared library of Gurobi, which should be
/Library/gurobi810/mac64/lib/libgurobi81.so in your case.<br>
<br>
If you want to update the links you can run "make LPS=grb
ZIMPL=false links", which will ask you for new targets.<br>
<br>
Best,<br>
Gerald<br>

Hi Nag,<br>
<br>
welcome to the SCIP mailing list. I recommend you switch to CMake
to compile SCIP, if available, which is much easier, especially on
non-Linux platforms. Please refer to<br>
<br>
<a class="moz-txt-link-freetext"
href="https://scip.zib.de/doc-6.0.2/html/CMAKE.php"
moz-do-not-send="true">https://scip.zib.de/doc-6.0.2/html/CMAKE.php</a><br>
<br>
In your case, the cmake command should be<br>
<br>
cmake .. -DGUROBI_DIR=/Library/gurobi810/mac64/ -DLPS=grb<br>
<br>
Happy branch-and-pricing,<br>
Gregor<br>

<div>I had never used SCIP before and I am hoping to use it for
branch and price. I had never used CPLEX before and I am
mostly familiar with GuROBi (I currently have my "column
generation" Framework in GuRoBi) but I am facing lot of issues
in trying to compile SCIP using GuRoBi as an LP solver. <br>
</div>
<div><br>
</div>
<div>I compile using <br>
</div>
<div><br>
</div>
<div>make LPS=grb ZIMPL=false<br>
</div>
<div><br>
</div>
<div>I am facing issues at these following areas:<br>
</div>
<div><br>
</div>
<div>> Enter soft-link target file or directory for
"lib/include/grbinc" (return if not needed): <br>
</div>
<div><br>
</div>
<div>I am not 100% sure where this directory is. I am currently
using this directory for the include<br>
</div>
<div><br>
</div>
<div> /Library/gurobi810/mac64/include<br>
</div>
<div><br>
</div>
<div>and then for the library<br>

<div>> Enter soft-link target file or directory for
"lib/shared/libgurobi.darwin.x86_64.gnu.so" (return if not

<div><br>

<div><br>
</div>
<div>/Library/gurobi810/mac64/lib<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>I think the paths are wrong as it is failing to compile.<br>

<div>This is the error I am getting:<br>

<div>I understand the error and SCIP is telling me that it

GuRoBi support is still in Beta but any help is appreciated. <br>
