<div dir="ltr"><div><div>Hi David,<br><br></div>I think I see what the problem is. I just made a change to the configure script that I hope will fix what you are seeing. In nutshell, the search path for the library was not set correctly. It was working for me because I happened to have another version of the library sitting in a system directory that I did not realize was there. I committed the change to trunk. Can you do "svn switch <a href="http://projects.coin-or.org/svn/SYMPHONY/trunk/SYMPHONY">http://projects.coin-or.org/svn/SYMPHONY/trunk/SYMPHONY</a>" in the SYMPHONY subdirectory and then see if the configuration works now?<br><br></div>Cheers,<br><br>Ted<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Oct 22, 2014 at 4:10 PM, Alfred Pennyworth <span dir="ltr"><<a href="mailto:batcavecluster@gmail.com" target="_blank">batcavecluster@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Dr. Ralphs,<div><br></div><div>No worries, I appreciate the help and understand that you have many other things to handle.</div><div><br></div><div>Yes, I would like to use SYMPHONY in a distributed environment.

What is your reason for trying to configure with --with-pvm? The CoinAll release 1.7.4 include a version of SYMPHONY for which I think PVM support is a bit broken. To use SYMPHONY with PVM, you should switch to the most recent release (5.6.1). You can do this easily with svn by going into the SYMPHONY subdirectory and doing<br><br></div><div>svn switch <a href="https://projects.coin-or.org/svn/SYMPHONY/releases/5.6.1/SYMPHONY" target="_blank">https://projects.coin-or.org/svn/SYMPHONY/releases/5.6.1/SYMPHONY</a><br><br></div><div>If you just want to solve in parallel on a multi-core machine, this will happen by default with 5.6.1 using OpenMP. You do not need any configure options. OpenMP support is automatically enabled. <br></div><span><div> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Previously, I had trouble installing PVM from source, but a helpful gentleman, Dr. Kohl, straightened me out. I have now gotten the source for PVM 3.4.6 and built it. I believe it to be working correctly. I have checked, and pvm3.h is in $PVM_ROOT/include. In my specific case, PVM_ROOT is /usr/share/pvm3/ and the CoinAll directory is /usr/share/CoinAll-1.7.4/.</div><div><br></div><div>Though, I am still having difficulty with CoinAll. After the checkout step, ./configure --with-pvm --enable-openmp (not sure if I need both, but the result is the same with or without the openmp flag) the error message is:</div><div>Cannot find PVM library in system paths or in PVM_ROOT path.</div></div></blockquote><div><br></div></span><div>This is a different problem. It is trying to find the PVM library, which should be in PVM_ROOT/lib/$PVM_ARCH, where PVM_ARCH is the architecture of the machine you are on. For me, it is LINUX64. Check to make sure there is such a directory and a library there. If not, perhaps you forgot to install? I can't remember, but it is possible, you also have to set the PVM_ARCH environment variable appropriately as well.<br></div><div> </div>Cheers,<br><br>Ted<span><font color="#888888"><br clear="all"></font></span></div><span><font color="#888888"><br>-- <br></font></span><div dir="ltr"><span><font color="#888888">Dr. Ted Ralphs</font></span><span><br>Professor, Lehigh University<br><a href="tel:%28610%29%20628-1280" value="+16106281280" target="_blank">(610) 628-1280</a><br>ted 'at' lehigh 'dot' edu<br><a href="http://coral.ie.lehigh.edu/~ted" target="_blank">coral.ie.lehigh.edu/~ted</a><br></span></div>
