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.

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 $PVM_ROOT/include. In my specific case, PVM_ROOT is /usr/share/pvm3/ and the CoinAll directory is /usr/share/CoinAll-1.7.4/.</div><div><br></div><div>Though, I am still having difficulty with CoinAll. After the checkout step, ./configure --with-pvm --enable-openmp (not sure if I need both, but the result is the same with or without the openmp flag) the error message is:</div><div>Cannot find PVM library in system paths or in PVM_ROOT path.</div></div></blockquote><div><br></div><div>This is a different problem. It is trying to find the PVM library, which should be in PVM_ROOT/lib/$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<br clear="all"></div><br>-- <br><div dir="ltr">Dr. Ted Ralphs<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></div>
