[PATCH 0/2] selftests/vm: fix some minor aggravating factors in the Makefile

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This fixes a couple of minor aggravating factors that I ran across while
trying to do some changes in selftests/vm. These are simple things, but
like most things with GNU Make, it's rarely obvious what's wrong until
you understand *the entire Makefile and all of its includes*.

So while there is, of course, joy in learning those details, I thought I'd
fix these little things, so as to allow others to skip out on the Joy if
they so choose. :)

First of all, if you have an item (let's choose userfaultfd for an
example) that fails to build, you might do this:

$ make -j32

    # ...you observe a failed item in the threaded output

# OK, let's get a closer look

$ make
    # ...but now the build quietly "succeeds".

That's what Patch 0001 fixes.

Second, if you instead attempt this approach for your closer look (a casual
mistake, as it's not supported):

$ make userfaultfd

    # ...userfaultfd fails to link, due to incomplete LDLIBS

That's what Patch 0002 fixes.
