Re: [Meep-discuss] C++ Interface

[rgomezal]

Hi Stephan,

Perhaps there is a more fast solution: try to install the Ubuntu
package "libmeep-dev" . It seems that is this package that contains
meep.pc and installs it under /usr/lib/pkgconfig/

If this works, you can compile your cpp files with procedure number two, i.e., 
using
pkg-config.
