Please describe your issue in as much detail as possible:

Every time I open Steam it displays a dialog with this message, after ok it is opened correctly

You are missing the following 32-bit libraries, and Steam may not run:
libc.so.6

Steps for reproducing this issue:

Open Steam

This seems to be a problem with Steam's detection of missing libraries. If you really didn't have a 32-bit libc.so.6, then Steam wouldn't be able to start at all.

@kisak-valve, please could you retitle this to "wrongly detects 32-bit libc.so.6 as missing" and transfer it to ValveSoftware/steam-for-linux?

This is probably a bug in get_missing_libraries() in ~/.steam/root/steam.sh. @josinaldobarbosa, if you run

LD_PRELOAD="" ldd ~/.steam/root/ubuntu12_32/steamui.so; echo "exit status $?"

what is the output?

@smcv

it is not a dynamic executable
exit status 1
