Hi,
When I want to compile Qt with cups, I get the following errors:#Note: I mounted the rootfs with sshfs and passed it to -sysroot option in ./configure.
Cups auto-detection... ()

collect2: error: ld returned 1 exit status
make: *** [cups] Error 1
Cups disabled.It's complaining about existing some libraries dependencies but i have all of them that location with proper symlinks. seems strange. Any solution to debug this problem?

Hi and welcome to devnet,
Might be a silly question but: did you install the corresponding dev packages on your BBB debian ?
-
@SGaist
Yes , their all installed by libcups2-dev packege , and for files that caused error:libgssapi_krb5.so.2
libgnutls-deb0.so.28
libavahi-common.so.3
libavahi-client.so.3
libz.so.1i have them all exactly in /usr/lib/arm-linux-gnueabihf/ of my bbb.
i can admit that i didn't have this problem in debian wheezy (7.x) with same version of Qt 5.6.0 . -
Silly test: try to run configure with your options and add
-L /mnt/bbb/usr/lib/arm-linux-gnueabihf/
(with the space) -
I solved the issue by passing -rpath-link as following paths to linker.
- /mnt/bbb/usr/lib/arm-linux-gnueabihf/
/mnt/bbb/lib/arm-linux-gnueabihf/
After some investigations i noticed qt already had this option, so i added this line:
DISTRO_OPTS += deb-multi-arch
to my qtbase/mkspecs/devices/linux-beagleboard-g++/qmake.confI think qt's documentation for embedded devices is not complete enough.
BTW: thanks for your help SGaist.

Glad you found out and thanks for sharing !
Are you trying to build the latest version of Qt ?
