  • Ticket #37845 – Description

    initial v1  
    11I'm trying to compile code that must interact with a 3rd party 32 bit library, and I can't link it because -m32 is not supported in the latest gcc48 compiler.
    22http://www.spinics.net/lists/gcchelp/msg36767.html indicates that when compiling and the error about 128 bit support appears it is due to not enabling multilib. Checking the specs on gcc48 shows:
     3{{{
    34nomultidefs
     5}}}
    46and multilib is empty for all instances
    57
     8{{{
    69*multilib:
    710. ;
    … …  
    1215*multilib_options:
    1316*multilib_reuse:
     17}}}
    1418
    1519When linking for 32 bits I get the following error:
    1620
     21{{{
    1722linking libmvpgemcomm32.so.7.0.0

    2026The code I'm using requires (now) the gcc std=c++11 code (mutex, condition_variable, futures, etc) so I can't use the older clang compiler.
