[yocto] [meta-qt5] static link plugin lib path problem

[Qiang Yu]

Hi all,

I use meta-qt5 for QT5 support. But I need static link the application so I
remove the -share from configure args and add -static.

The "bitbake qtbase" is fine, but "bitbake qtxmlpatterns" do_compile fail:
| linking ../../bin/xmlpatterns
|
/opt/yocto-rel/yocto/0.1/build/linda-a20navi/tmp/sysroots/x86_64-linux/usr/libexec/arm-linda-linux-gnueabi/gcc/arm-linda-linux-gnueabi/4.9.1/ld:
warning: library search path "/usr/lib/qt5/plugins/bearer" is unsafe for
cross-compilation

/opt/yocto-rel/yocto/0.1/build/linda-a20navi/tmp/sysroots/x86_64-linux/usr/libexec/arm-linda-linux-gnueabi/gcc/arm-linda-linux-gnueabi/4.9.1/ld:
cannot find -lqgenericbearer
| collect2: error: ld returned 1 exit status

I find the Makefile generated by qmake for tools/xmlpatterns has the wrong
LIBS:
LIBS          = $(SUBLIBS)
-L/opt/yocto-rel/yocto/0.1/build/linda-a20navi/tmp/work/cortexa7hf-vfp-vfpv4-neon-linda-linux-gnueabi/qtxmlpatterns/5.3.2-r0/build/lib
-lQt5XmlPatterns -lQt5Network -lQt5Core -lz -lm -ldl -lrt
-L/usr/lib/qt5/plugins/bearer -lqgenericbearer -lpthread

It seems the plugin lib dir doesn't have a cross compile prefix. Any one
meet this problem before or know how to fix static link plugin lib path?

Thanks,
Qiang
