[ ... looking through the log ... ]

They don't get deleted later.  The files to be installed don't get
created to begin with.  This is arguably a bug in the sane-backends
build system but you can easily work around it by running a `make`
before doing a `make install`.

It looks like the homebrew stuff assumes that `make install` will be
smart enough to also trigger builds for everything that needs to be
installed.  A bit overly optimistic, if you ask me ;-)

Below is the Makefile.am snippet that installs the configuration files.
The first line after the @list, checks for a readable configuration but
because all these files are generated they don't exist unless you run a
`make install` first.

  install-becfg:
  @# Libtool has a bug where it will sometimes symlink the last
  @# installed library in $(sanelibdir) to $(sanelibdir)/libsane.*.
  @# Having two libsane's can cause issues so get rid of it.
  -rm -f $(DESTDIR)$(sanelibdir)/libsane.*
  test -z "$(configdir)" || $(MKDIR_P) "$(DESTDIR)$(configdir)"
  test -z "$(configdir)/dll.d" || $(MKDIR_P) 
"$(DESTDIR)$(configdir)/dll.d"
  @list="$(BACKEND_CONFS_ENABLED) saned.conf dll.conf"; for cfg in 
$$list; do \
if test ! -r $${cfg}; then continue; fi; \
if test -f $(DESTDIR)$(configdir)/$${cfg}; then \
echo NOT overwriting $${cfg} in $(configdir)...; \
else \
echo installing $${cfg} in $(configdir)/$${cfg}...; \
$(INSTALL_DATA) $${cfg} $(DESTDIR)$(configdir)/$${cfg} \
|| exit 1; \
fi; \
done

I pushed a fix for this in 519ff57.

Hope this helps,

Re: [sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

[schmo-fu]

Okay, here i go again ...

i can confirm, that it is not a permission problem. It's just that there
are no files, where they should be.

The scanner is recognized by sane-find-scanner now. But scanimage -L
doesn't find it, because the sane-backends .conf files are supposed to
be at:
/usr/local/Cellar/sane-backends/1.0.27_1/etc/sane.d/
but there is no etc/ (and there also is no doc/; both are present under
1.0.25_1; (»officially« there should also be a tools/, but this isn't
present neither in 25 nor in 27).

Looking at
https://gist.github.com/anonymous/5e324f6e1c7c8b9ea4172a72e0352255
[[see note]]
the make-log shows, that the backends are all build with
"-DPATH_SANE_CONFIG_DIR=usr/local/Cellar/sane-backends/1.0.27_2/etc/sane.d"
which seems alright.

Maybe they get deleted later? I don't know enough about this process, to
know where to look for answers.
@Yurii can you help with this?


Greetings,
Thomas.S

[[ Note:
I corrected and reintroduced the patch from 1.0.25, that fixes some

Re: [sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

[schmo-fu]

Yuri,

that's only part of the solution.

I tried
» brew reinstall
https://raw.githubusercontent.com/yurikoles/homebrew-core/sane-backends-1.0.27-1/Formula/sane-backends.rb
«

but it leads to error:
  curl: (22) The requested URL returned error: 401 Unauthorized
  Error: Failed to download resource "sane-backends"
  Download failed:
https://homebrew.bintray.com/bottles/sane-backends-1.0.27_1.sierra.bottle.tar.gz

»brew reinstall --build-from-source https://raw.github... « went fine.

I then also edited fxcouderts changes into my own Formula, but:
while »depends_on "pkg-config"« helps (as i wrote before)
but the added »=> :run« or »=> :build« don't make it any better.

The build-log shows »checking for USB... yes« now in any of the three
cases, but the scanner is still not detected.

This is a big step into the right direction, but not the whole way.

 Hey Olaf and Yurii,

 thank you for your support, there is some progress:
 First i replaced usb-compat- with libusb-dependency in the formula.
 sane-backends compiled, but still no usb-support.
 Then i put »depends_on "pkg-config"« into the formula.

 And here we go:
 [sanei_usb] sanei_usb_init: initializing libusb-1.0
 [sanei_usb] sanei_usb_scan_devices: marking existing devices
 [sanei_usb] libusb_scan_devices: Looking for libusb-1.0 devices
 [sanei_usb] libusb_scan_devices: device 0x04a9/0x221c at 038:002 is not
 configured
 [sanei_usb] libusb_scan_devices: found libusb-1.0 device (0x05ac/0x8215)
 interface 0 at libusb:006:003
 [sanei_usb] store_device: add dn 0 with libusb:006:003

 Wow! This looked so good, until i realized that the device 0x04a9 "is
 not configured" (and the other one is just the
>> Bluetooth-USB-Controller).
 So »scanimage -L« tells me, that there is still no scanner.
 But this may be an unrelated issue, or isn't it?
 (The scanner btw. is a CanoScan LiDE 60. Switching back to sane-backends
 1.0.25 shows this:
 found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan],
 chip=GL842) at libusb:038:002).

 Ah, here is the log:

Re: [sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

[schmo-fu]

Hi Tom,

you would have to install homebrew (see https://brew.sh/)

After that you simply type "brew install sane-backends" this will
install a binary (called bottle). The binaries are installed to
/usr/local/Cellar/... and symlinked /usr/local/bin/

To compile your own brew (after changing something in the formula for
example) you would enter "brew install --build-from-source sane-backends".

The formula is a ruby-file found at:
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/sane-backends.rb

You probably know how to test whether it finds any scanners, but anyway:
you use "sane-find-scanner -v" and "scanimage -L".

Thomas.S

Re: [sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

[schmo-fu]

Hey Olaf and Yurii,

thank you for your support, there is some progress:
First i replaced usb-compat- with libusb-dependency in the formula.
sane-backends compiled, but still no usb-support.
Then i put »depends_on "pkg-config"« into the formula.

And here we go:
[sanei_usb] sanei_usb_init: initializing libusb-1.0
[sanei_usb] sanei_usb_scan_devices: marking existing devices
[sanei_usb] libusb_scan_devices: Looking for libusb-1.0 devices
[sanei_usb] libusb_scan_devices: device 0x04a9/0x221c at 038:002 is not
configured
[sanei_usb] libusb_scan_devices: found libusb-1.0 device (0x05ac/0x8215)
interface 0 at libusb:006:003
[sanei_usb] store_device: add dn 0 with libusb:006:003

Wow! This looked so good, until i realized that the device 0x04a9 "is
not configured" (and the other one is just the Bluetooth-USB-Controller).
So »scanimage -L« tells me, that there is still no scanner.
But this may be an unrelated issue, or isn't it?
(The scanner btw. is a CanoScan LiDE 60. Switching back to sane-backends
1.0.25 shows this:
found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan],
chip=GL842) at libusb:038:002).

Ah, here is the log:

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.

I have zero idea about homebrew works but the paths of the *.pc files
themselves and the prefixes they list look highly suspicious.  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.

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".

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,

i copied the contents of the two pc-files to this pad:
https://codicill.us/pad/p/gist

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?

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.

[sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

[schmo-fu]

Hi,

i want to report a problem with sane-backends 1.0.27 on MacOS
installation via homebrew package management.
I wrote to one of the maintainers (Yurii on Cc:) of the homebrew-formula
first. He send me here, because it's not a compilation problem.
The formula installed fine, but the resulting sane-backend is built
without usb support.


Here is how and what i found out:
xsane suddenly didn't find my USB-Scanner anymore. I checked the scanner
with another computer and it's fine. I looked into the debug-output and
... long story short:
Debug information from sane-find-scanner says:
"sanei_usb_init: SANE is built without support for libusb"

Since i "brew upgrade"d since my last use of the scanner, i switched
back to 1.0.25_1 and this fixed the problem.
Reinstalling 1.0.27 with --build-from-source reproduced the problem.

The strange thing is, that the sane-backends.rb-file (the homebrew
automatic installation instruction) clearly states
"--enable-libusb" in both versions. But config-warnings for 1.0.27 say
"unrecognized options: --enable-libusb" which is in accordance with the
NEWS note 2, that libusb is now the default, but something seems to be
broken here.
I changed the formula so that it states "--with-usb" but that didn't
help. (No warning anymore, but still no USB)

The last 1.0.25-homebrew-commit contained a patch (concerning some
missing headers) that later commits are missing. (What this patch did
exactly and whether this is related to the usb-problem is beyond me.)

Finally i can say that homebrew-commit
7aaf1e3a14b75a715eed34f3bb4c57e79f417e96 works, while the next commit
60b1305361d0ef61405014b37164b1daaf77d207 doesn't.


I hope all of this makes sense to you and someone has time to look
into this problem.
