[Coin-discuss] shared vs static libs

[Ted Ralphs]

I think most of the libraries have a flag to just enable debugging for
that library alone. For instance, SYMPHONY has --enable-debug-symphony.
This doesn't allow fine-tuning of the optimization level for optimized
code, but it gives you some control.

Cheers,

Ted

You typically want static libraries when debugging, but I think if you specify that only a particular library should be compiled with debugging, then the others will be built shared, right?
