[lustre-discuss] Compiling latest lustre client.

[Glossman, Bob]

Phil,
  This is a known issue and is due to using gcc 5.   While it never did make much sense to have ‘extern inline’ declarations in #include files, all previous versions of gcc silently allowed it.  In gcc 5 it generates errors.  There is a bug fix planned, but not landed yet.  It hasn’t been an acute problem as none of the linux distros we have committed support for are using gcc 5 yet.

If you want to fix it on your own until we have an official patch landed, just remove the ‘inline’ keyword from all the offending definitions, both in the .h files and in the .c files where the functions are actually defined.

    Trying to compile the latest lustre client to try and resolve my hanging 
    issue, followed the following procedure :
    
    git clone git://git.whamcloud.com/fs/lustre-release.git
    cd lustre-release
    sh autogen.sh
    ./configure --disable-server --with-o2ib=no
    make
    
    It compiles a whole bunch of stuff then bombs out with :

    Any clues?
