[Ipopt] Ipopt 3.4.0 installation on Intel Mac

[Andreas Waechter]

Hi Ray,

I don't have a access to a Mac, but I know of people how have successfully 
compiled Ipopt under Darwin.

1. It seems that you are using compilers from different major GCC 
releases.  I would not be surprised if that causes problems.

2. I think that other Darwin users have been able to get around this 
problem during the sizeof check by explicitly taking off the 
"-pedantic-errors" compilation flag.  To do this, add the following 
arguments to your configure command:

CFLAGS='-O3 -fomit-frame-pointer -pipe -DNDEBUG'
CXXFLAGS='-O3 -fomit-frame-pointer -pipe -DNDEBUG'

This will overwrite the default compiler flags (that include 
-pedantic-errors).

I hope this helps,

Andreas
