static link version QT5 module qtxmlpatterns compile problem

Hi all,

I'm building a static link version of QT by add -static to qtbase configure. The qtbase compile is fine. The I switch to qtxmlpatterns which compile fail with:

Code:

---

| 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

| collect2: error: ld returned 1 exit status

I find the Makefile generated by qmake for tools/xmlpatterns has the wrong LIBS:

Code:

---

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

---

the share link version of the same Makefile's LIBS has no plugin link:

Code:

---

LIBS          = $(SUBLIBS) -L/opt/yocto/build/sunxi/linda-a20navi-base/tmp/work/cortexa7hf-vfp-vfpv4-neon-linda-linux-gnueabi/qtxmlpatterns/5.3.2-r0/build/lib -lQt5XmlPatterns -lQt5Network -lQt5Core -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

I find the problem:

qt.prf:

Code:

---

plugpath = $$[QT_INSTALL_PLUGINS/get]

---

both $$[QT_INSTALL_PLUGINS/get] and $$[QT_INSTALL_PLUGINS/raw] equal /usr/lib/qt5/plugins
but $$[QT_INSTALL_PLUGINS] equals right path.

Now my question is
1. why there are three var of QT_INSTALL_PLUGINS?
2. where are their values from?

Thanks,
Qiang

Have you tried $$[QT_INSTALL_PLUGINS]/get and $$[QT_INSTALL_PLUGINS]/raw?

Edit: Sorry, just realized that you are referencing qt.prf, not something you coded. Please disregard my reply.

I find some valuable info from
https://github.com/meta-qt5/meta-qt5...ilding-with-OE

Now I use $$[QT_INSTALL_PLUGINS] which qmake will prefix /usr/lib/plugins with SYSROOT.
But the Makefile has another problem when upgrade to 5.4:

Code:

---

LIBS          = $(SUBLIBS) -L/opt/yocto-rel/yocto/0.1/build/linda-a20navi/tmp/work/cortexa7hf-vfp-vfpv4-neon-linda-linux-gnueabi/qtxmlpatterns/5.4.0-r0/build/lib -lQt5XmlPatterns -L/opt/yocto-rel/yocto/0.1/build/linda-a20navi/tmp/sysroots/a20navi/usr/lib/qt5/plugins/bearer -lqgenericbearer -L${libdir} -lQt5Network -lQt5Core -lz -lm -ldl -lrt -lpthread

---

The ${libdir} expend to /usr/lib which is cross-compile unsafe.

Added after 59 minutes:

The libdir problem occurs when I change $$[QT_INSTALL_PLUGINS/get] to $$[QT_INSTALL_PLUGINS].
