Make error when trying to build QT app for an "Open Embedded2 device

Question

I am getting this error when trying to build my app:

make: Wl,-rpath-link,: Command not found

My Makefile looks like this, which is a generated file useing qmake program in the OE toolchain.

Does anybody recognize the error and know why it emerges?

Thanks in advance. :)

Answer 1

The error is generated because the variable $(OE_QMAKE_LIBDIR_QT) doesn't exist. So

-Wl,-rpath-link,$(OE_QMAKE_LIBDIR_QT)

becomes

-Wl,-rpath-link,

Are you setting the other variables like $(OE_QMAKE_CC) and $(OE_QMAKE_CXX), and if so, where? You should add the variable above to this list. It should point to the lib subdir of your Qt installation.

This could be for example (here it's Qt version 4.8.0): /usr/local/Trolltech/Qt-4.8.0/lib.

In a local installation in your home directory, it may look like this: ~/qt/Desktop/Qt/4.8.1/gcc/lib.

For Qtopia, you should look in /usr/local/oecore-i686/sysroots...
