           Summary: Parallel install in multiple jobs as in "make -j99
                    install" fails
           Product: Wine
           Version: 1.1.4
          Platform: All
               URL: https://bugs.gentoo.org/show_bug.cgi?id=237011
        OS/Version: All
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org

Installing wine in parallel, like running "make -j99 install", has a high
probability of failure. Errors look like this:

make[2]: Entering directory `.../wine-1.1.4/dlls/wintab32'
/usr/bin/install -c   wintab32.dll.so /usr/lib/wine/wintab32.dll.so
make[2]: Entering directory `.../wine-1.1.4/dlls/wintab32'
/usr/bin/install -c   wintab32.dll.so /usr/lib/wine/wintab32.dll.so
/usr/bin/install: cannot create regular file `/usr/lib/wine/wintab32.dll.so':
File exists
make[2]: *** [install] Error 1
make[2]: Leaving directory `.../wine-1.1.4/dlls/wintab32'
make[1]: *** [wintab32/__install__] Error 2
make[1]: *** Waiting for unfinished jobs....

The reason for this is that the dlls subdir is entered twice, once for the
target "install" as dlls is part of INSTALLSUBDIRS, and once for the target
"install-lib" as required as a dependency of programs/__install__.

The dependency on install-lib has been present in the tree for quite some time
now, and was first introduced by Alexandre Julliard in 2002 according to
http://source.winehq.org/git/wine.git/?a=commit;h=ada5e6521bfb0ca5

The inclusion of dlls in INSTALLSUBDIRS seems to be a recent modification which
was not present in 1.1.3. It's again by Alexandre Julliard according to
http://source.winehq.org/git/wine.git/?a=commit;h=b3ec2e5f95e36aa9

The issue surfaced quite frequently on Gentoo Linux, as Gentoo encourages
building packages from source and employing parallel builds for this. See also
the original report at https://bugs.gentoo.org/show_bug.cgi?id=237011
There you can also find a patch which seems to work around the problem.
