Hello,
there is two possibilties:
- enable libcwd support (http://libcwd.sourceforge.net/) by passing
-DCWDEBUG as CXXFLAGS
(using ccmake for instance)
This has not been thoroughly tested and minor compilation errors may occur.

- use the plug-in specific logging features using solver.parameters () method.
In this case, take a look to the plug-in documentation / code to see
what parameters are available.
For instance, using the CFSQP plug-in, "cfsqp.iprint" can be used to
dump intermediate steps.

BTW, other options are also available to fine tune the KKT condition
evaluation which decides whether
the optimization should stop or not.
