Using pkgsrc, build and install libtool 2.4.2 to the root partition. Using pkgsrc, try building and installing software that uses libtool. What I expected to happen: Succeed at building and installing software that uses libtool. What actually happened: Fail, like so (in this example, pkg-config): [...] CC gprintf.lo CC glib-unix.lo CC gthread-posix.lo CC giounix.lo CC gspawn.lo CCLD libglib-2.0.la libtool: link: Waiting for /Volumes/pkgsrc/current/devel/pkg-config/work.ap-juicer/pkg-config-0.28/glib/glib/libcharset/.libs/libcharset.a.lock to be removed libtool: link: Waiting for /Volumes/pkgsrc/current/devel/pkg-config/work.ap-juicer/pkg-config-0.28/glib/glib/libcharset/.libs/libcharset.a.lock to be removed libtool: link: Waiting for /Volumes/pkgsrc/current/devel/pkg-config/work.ap-juicer/pkg-config-0.28/glib/glib/libcharset/.libs/libcharset.a.lock to be removed [repeats forever] What I've figured out so far: * The error message comes from func_extract_an_archive() (and not the other occurrence of "to be removed"). * It's conditionalized on lock_old_archive_extraction being "yes", which is true only on Darwin. * It attempts to create a lockfile as a hardlink to libtool itself, which fails when the installed libtool is not on the same filesystem as the source being built. * It assumes the only reason the hardlink could fail is the target already existing. * When it fails for any other reason, a wrong conclusion goes to stderr, the real error goes to /dev/null, and we're stuck in an infinite loop. * If I set lock_old_archive_extraction=no, everything works as expected in my limited testing. What I haven't figured out, and am asking you to: * What Darwin-specific problem is lock_old_archive_extraction trying to prevent? I see that the variable was introduced 2009-06-10, accompanied by an automated test to verify that convenience archive extraction works concurrently. I couldn't figure out at a glance how to run that test, so I'm not sure whether a working lock_old_archive_extraction would have done me any good. What have I broken on my Darwin system by setting it to "no"? In what context is it still needed? (I'm guessing there is one, but if it turns out there isn't, removing lock_old_archive_extraction and related codepaths would solve my problem.) * Can the locking code (if it needs to live) print the actual error when there is one, so that future problems are less confusing? * Can the locking code (if it needs to live) either work entirely within the build area or not rely on hardlinks, so that it works in a filesystem configuration like mine? Thank you for libtool and for reading this bug report!
