I'm trying to build an application. It requires the next libs: libev(x86-32) libev(x86-64) libev-devel(x86-32) libev-devel(x86-64) for Ubuntu I run:
sudo apt-get install libev-dev
and get libev4 and libev-dev. But if I run
sudo apt-get install libev-dev:i386
it wants to remove old libev. I need all these libraries to compile versions for different platforms. How to install them all?
