Re: [Liberty-eiffel] [SOLVED] eiffel-iup on Windows

[Germán Arias]

I found a better solution. Instead use a file called "linker_options"
in my plugin, now I have one called "libs". Initially I use
"linker_options" because I use the "minigtk" example as reference. But
looking inside the Liberty Eiffel plugins they use "libs" not
"linker_options". So sorry for the noise.

Thanks
Germán
