Public bug reported: I'm a software developer. I tried to build for 32 bit Linux on 64 bit Linux, to check type cast warnings occurring only for 32 bit versions. But it seems I cannot build for 32 bit on my 64 bit machine - gcc -m32 will fail with "/usr/bin/ld: cannot find -lgcc". Googled for a solution and found https://www.cyberciti.biz/tips/compile-32bit-application-using-gcc-64-bit-linux.html Typed "sudo apt-get install g++-multilib libc6-dev-i386".
Then an error message popped up. lsb_release -rd Description: Ubuntu 16.04.2 LTS Release: 16.04 ProblemType: Package DistroRelease: Ubuntu 16.04 Package: libc6-dev-i386 (not installed) ProcVersionSignature: Ubuntu 4.4.0-64.85-generic 4.4.44 Uname: Linux 4.4.0-64-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.10 Architecture: amd64 Date: Sat Jul 29 20:19:44 2017 DpkgTerminalLog: Vorbereitung zum Entpacken von .../libc6-dev-i386_2.23-0ubuntu9_amd64.deb ...
