At first I thought cbc was not writing .sol file. It is but it
puts it out directory where .nl file is. So look there.<br>

</div>
<div>If you have a problem in the .nl format you can solve it
with the CBC driver for AMPL and write a .sol file as follows:</div>
<div><br>
</div>
<div> cbc <stub> -AMPL</div>
<div><br>
</div>
<div>where <stub> is the name of the .nl file without an
extension.<br>

Dear CBC team,<br>
we successfully use CBC (2.7.7) for AMPL models via
OSAmplClient from AMPL translator.<br>
But now, to "distribute" the computational load, we need
to run CBC application on one server, but perform
analysis of solution in AMPL translator running on
another server.<br>
The most convenient would be if CBC-solution will be
returned in AMPL format (*.sol file created by
write_sol ASL routine). <br>
But not in CBC nor in OSSolverService I can not find an
option (similar to "wantsol" for AMPL-solvers) telling
to write solution in AMPL format. <br>
At the same time in CbcSolver.cpp I see a call of
writeAmpl(...) procedure, defined in Cbc_ampl on the
base of an ASL write_sol(...).<br>
<br>
May be there are some "hidden" options of CBC (or
OSSolverService) or "tricks" of compilation ?<br>
We'll be happy for any hints.<span class="HOEnZb"><br>
