If you can do something like this (in linux) would that work?<br>
<br>
cat test.lp |bin/cbc -import stdin_lp -solve<br><div class="im"></div></blockquote><div><br>I thought it used to be that the filename "-" *or something similar meant that the file should be read from stdin. Am I mis-remembering?<br>

Welcome to the CBC MILP Solver<br>
<br></div>
command line - bin/cbc -import stdin_lp -solve (default strategy 1)<br>
Continuous objective value is 3.23684 - 0.00 seconds<br>
Cgl0004I processed model has 1 rows, 3 columns (0 integer) and 3 elements<br>
Cbc3007W No integer variables - nothing to do<br>
<br>
I have committed fixes to trunk - key thing is to import from stdin_lp (exact spelling needed)<br>

Does anyone know how to get GMPL working on Windows?<span class="HOEnZb"><font color="#888888"></font></span><br></blockquote><div><br>I got it working once a long time ago. It was fairly straightforward using GLPK's Visual Studio project. The only tricky part is that you have to set a few compiler defines by hand in the CBC Visual Studio file. I can try to replicate, but not in the very near future.<br>
<br>Unfortunately, we cannot distribute binaries with GMPL built in because of licensing issues (basically because GLPK is licensed under the GPL). A while back, I put a modest effort into getting an exception for COIN codes to link to GLPK, but it didn't go anywhere.<br>
