I've been using __DECOMP_IP_CPX__ lately and everything has been working fine (when using --with-ip-solver=cpx).<br><br>I found the issue. __DECOMP_IP_CBC__ is no longer being defined by default. It is odd, because __DECOMP_LP_CLP__ is defined as normal.<br>
<br>So, basically, DIP is building with no IP solver which is causing failures on all the tests.<br><br>Something must have changed recently in the build tools or DIP build files. Ted is in charge of that stuff, so I will need his help on this one. Ted - can you take a look?<br>

Make test fails for me too (at trunk). I'll take a look ASAP.<br><br> unitTest: ../../../Dip/src/DecompAlgo.cpp:748: virtual void DecompAlgo::createMa sterProblem(DecompVarList&): Assertion `initVars.size() > 0' failed.<br>

For the newer versions of DIP ("0.81.1", "0.81.2" and "trunk") I can no<br>
longer get the examples to work.<br>
<br>
After installation, when I run examples they return simply:<br>
"Alps0240I Processed 0 nodes, has 0 nodes, best relaxed 1e+75, best<br>
feasible 1e+75<br>
<br>
Alps0202I Problem is infeasible. 1 nodes processed, 0 nodes left<br>
Alps0264I No solution found<br>
"<br>
<br>
This is the output from "make test" after installation as well as the<br>
"MILP" and "MILPBlock" examples. I cannot get "GAP" and "MMKP" to<br>
compile at all.<br>
<br>
My install sequence, in case I'm doing something wrong:<br>
1) svn checkout <a href="https://projects.coin-or.org/svn/Dip/releases/0.81.2" target="_blank">https://projects.coin-or.org/svn/Dip/releases/0.81.2</a><br>
Dip-0.81.2<br>
2) cd Dip-0.81.2<br>
3) mkdir build<br>
4) cd build<br>
5) ../configure<br>
6) make<br>
7) make install<br>
8) make test (this is the first time an example unexpectedly returns "no<br>
feasible solution")<br>
9) cd Dip/examples/MILPBlock<br>
10) sh data_extract.sh<br>
11) make<br>
12) ./decomp_milpblock --param milpblock.parm (this too gives a "no<br>
solution" result)<br>
<br>
I have since tried with different instances and with different examples<br>
with the same result.<br>
