#31531: sane-backends: USB support requested but required libraries not found ------------------------------+--------------------------------------------- Reporter: sjd4@… | Owner: aguynamedryan+sane@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.3 Keywords: | Port: sane-backends ------------------------------+--------------------------------------------- Comment(by erniefourman@…): I'm seeing the same problem, but with perl5.12 -universal active. I took a look in the libusb libraries, and the _usb_interrupt_read symbol is listed as defined. Perhaps a stupid question, but why does libusb-compat@0.1.3 give me libusb-0.1.4.dylib rather than libusb-0.1.3.dylib? nm /opt/local/lib/libusb-0.1.4.dylib | grep _read 0000000000001770 T _usb_bulk_read 00000000000014d0 T _usb_interrupt_read nm /opt/local/lib/libusb.a | grep _read 0000000000000c10 T _usb_bulk_read 0000000000002de8 S _usb_bulk_read.eh 0000000000000970 T _usb_interrupt_read 0000000000002d78 S _usb_interrupt_read.eh <snip> checking usb.h presence... yes checking for usb.h... yes checking for usb_interrupt_read in -lusb... no configure: error: USB support requested but required libraries not found. shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports .org_release_ports_graphics_sane-backends/sane-backends/work/sane- backends-1.0.22" && ./configure --prefix=/opt/local --mandir=/opt/local/share/man --with-docdir=/opt/local/share/doc/sane- backends --enable-local-backends --enable-libusb --disable-latex --without-gphoto2 " returned error 1 </snip> port -v installed perl5.12 The following ports are currently installed: perl5.12 @5.12.3_1 platform='darwin 10' archs='x86_64' perl5.12 @5.12.3_1+universal platform='darwin 11' archs='i386 x86_64' perl5.12 @5.12.3_2-universal (active) platform='darwin 11' archs='x86_64' perl5.12 @5.12.3_2+universal platform='darwin 11' archs='i386 x86_64' port -v installed net-snmp The following ports are currently installed: net-snmp @5.7_0 (active) platform='darwin 11' archs='x86_64' -- Ticket URL: <https://trac.macports.org/ticket/31531#comment:15> MacPorts <http://www.macports.org/> Ports system for Mac OS
