Cross-compiling for old ARM Embedded Linux. Lookup errors: undefined symbol

lukegluke

Hi all,

I have embedded arm linux device with old 2.6 kernel and Qt-5.4 libs. But I need Qt-5.9.5.
I was able to cross compile Qt-5.9.5 libs and can now successfully run quick applications using updated new version of libc (and other related libraries) .

But if I run app with "export LD_DEBUG=libs"
I see following symbol lookup errors:

for libQt5Qml.so:

/opt/device/Qt-5.9.5/lib/libQt5Qml.so.5: error: symbol lookup error: undefined symbol: qmlmemprofile_stats (fatal)

and also the same for symbols qmlmemprofile_clear, qmlmemprofile_enable, qmlmemprofile_disable, qmlmemprofile_push_location, qmlmemprofile_pop_location, qmlmemprofile_save, qmlmemprofile_is_enabled

for libQt5Gui.so

/opt/device/Qt-5.9.5/lib/libQt5Gui.so.5: error: symbol lookup error: undefined symbol: glClearDepth (fatal)

(and so on - about 1000 lines about missing opengl funcitons)

As I said regardless to those errors application works.
There are no such symbol lookup errors for applications builded against original Qt-5.4.

Besides other flags, there are -lGLESv2 -lOpenVG -lEGL building flags.
Libs libOpenVG.so, libGLESv2.so are in related lib path and they are used according to log.

I'm new in such crosscompiling and using multiple version of libc on the same system. I think I missed somewhere and do not add all needed libs.

Thanks in advance for any help!

Just in case if it can help qt.scenegraph.general info:
