You find the log here: > https://gist.github.com/anonymous/5ea27bd1a4c1f0baffebffe7aec0caf3 That has: checking for USB... no checking for USB... no checking usb.h usability... yes checking usb.h presence... yes checking for usb.h... yes checking for usb_interrupt_read in -lusb... yes checking lusb0_usb.h usability... no checking lusb0_usb.h presence... no checking for lusb0_usb.h... no So it *does* find some usable USB support and hence won't bomb. From the comment in configure.ac, that first `yes` hints at a 10+ years old libusb (or Windows version). I *think* it found something from that libusb-compat package. >> From the config.log I see that there's probably a libusb-compat >> installed somewhere.

That is, the files live below /usr/local/opt/ but their prefix point below /usr/local/Cellar/. There may be some symlinks to make this all work, magically, but to me it looks fishy. If those *.pc files are found when running ./configure, that excerpt of the ./configure output quoted above should reduce to just checking for USB... yes and USB should work. The ./configure script makes sure that pkg-config (which deals with these *.pc files) is set up correctly for your build environment before it tries to find the *.pc files. From the initial ./configure output excerpt it very much looks like they are *not* found at all. > Then i force uninstalled libusb-compat. > That stopped sane-find-scanner from working (See error-message at the > end of the pad). So this looks more like sane-find-scanner is actually > build with usb-support? Yup. And if I am not mistaken, that came from libusb-compat which you subsequently nuked. The error message is interesting though (in light of those *.pc files you pasted). dyld: Library not loaded: /usr/local/opt/libusb-compat/lib/libusb-0.1.4.dylib The libusb.pc mentions a version of 0.1.5_1 (emulated_by=libusb-1.0 ??) and libusb-1.0.pc mentions 1.0.21. Hmm, libusb is 0.1.5? Seriously? The latest version is 0.1.12 and that was released years ago. How does that jive with a 0.1.4.dylib? # I'm not expecting you to answer this. I am just thinking "out loud". > So i reinstalled (build-from-source) sane-backends (after deactivating > the dependency for libusb-compat) and it bombed (of course). > Logs from that: https://gist.github.com/dfbe878620c1ae20f1bcbda44dbe37e3 > > So i reinstalled libusb-compat and now i'm back to where i started. Based on the above, I would drop the 10+ year old duct tape that goes by the name of libusb-compat and look at fixing whatever thwarts pkg-config finding one of those *.pc files, preferably libusb-1.0.pc. Hmm, ... Having another round through the info in the various links you and Yurii provided I noticed checking for pkg-config... no Is homebrew using pkgconfig instead? If so, I'd suggest adding something like system "ln", "-s", "pkg-config", "/usr/bin/pkgconfig" *before* running configure to sane-backends.rb. Adjust /usr/bin as necessary. While at it, also drop the depends_on "libusb-compat" or replace it with something like depends_on "libusb-1.0" at least, do yourself a favour and build against libusb-1.0. So far for tonight's debugging session ;-) If you still have trouble, don't hesitate to "bother" me (and the list ;-) Hope this helps, -- Olaf Meeuwissen, LPIC-2 FSF Associate Member since 2004-01-27 GnuPG key: F84A2DD9/B3C0 2F47 EA19 64F4 9F13 F43E B8A4 A88A F84A 2DD9 Support Free Software https://my.fsf.org/donate Join the Free Software Foundation https://my.fsf.org/join -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org
