[Ipopt] Static libraries produce a bunch of warnings

[Paul Smith]

Dear All,

I have compiled Ipopt with the option --enable-static, and when I use
the Ipopt static libraries to use Ipopt from inside a C++ program, I
get a bunch of warnings. (Please, find below some of these warnings.)
Can these warnings be avoided? My code is the one that comes with the
cpp_example in the Ipopt distribution, and the binary that I get after
compiling this example works fine.

Thanks in advance,

Paul
