When I run

sudo apt-get install libcurl4-openssl-dev:i386

It removes libcurl4-openssl-dev package and vice-versa. How can I install both versions, for building both 32-bit and 64-bit version, of my program on one machine?

  • Why do you need this? – Tim Aug 18 '14 at 19:54
  • Try MultiArch it works for you [enter link description here](https://help.ubuntu.com/community/MultiArch#Installing) – Bipul kumar Aug 18 '14 at 20:03
  • I need this to build both versions on my build machine – Alexey Aug 19 '14 at 00:18
  • Can someone explain how MultiArch works? Why instead of installing somePackage:amd64 and somePackage:i386 I need to install some magic metapackage that contains 32bit versions of some libs? What if ia32-libs-multiarch doesnt contain 32bit library I need? – Alexey Aug 19 '14 at 00:20
