[Coin-ipopt] Problem with Intel compilers on linux

[Andreas Waechter]

Hi Yohan,

There might be a problem with the Intel compiler on your system.  The
configure scirpt output says that it was trying to compile the program:

and got this output from the compiler:

Please try if you have problems compiling a simply C++ program with the
Intel compiler that includes <cmath> and uses it, for example,

#include <cmath>
main () {
  double x;
  x = sin(2.);
}

If that doesn't work, something with your compiler installation is not
working.
