Title: Can\'t link libqpe for qvfb
Post by: koan on February 25, 2004, 09:13:43 am

Hi,

I\'m learning about QPE and Qtopia by writing some test apps.

I can link to libqpe for apps to run on my zaurus but when I try to compile an app to run on qvfb on my desktop, I can\'t link. The message I get is:
 
 /opt/Qtopia/lib/libqpe.so: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

Somehow, I don\'t have the right version of that library.
Can anyone help me figure out what I need to do to link to libqpe ?

I\'m running SuSE 8.2 and I installed qtopia-free 1.5.

] arm-linux-g++ -v
Reading specs from /opt/Embedix/tools/lib/gcc-lib/arm-linux/2.95.2/specs
gcc version 2.95.2 19991024 (release)

I\'m using the standard dev-x86-qpe.sh script.

thanks in advance

Ah, I should always make sure to run tmake each time I switch between ARM and x86 development.

Now my problem is that I\'m not linking against QPE properly:

gcc  -o display MainWindow.o main.o moc_MainWindow.o  -L/opt/Qtopia/lib -lqpe -lqte
MainWindow.o(.text+0x2b): In function `MainWindow::MainWindow[not-in-charge]()\':
: undefined reference to `QMainWindow::QMainWindow[not-in-charge](QWidget*, char
 const*, unsigned)\'
MainWindow.o(.text+0x30): In function `MainWindow::MainWindow[not-in-charge]()\':
: undefined reference to `QString::shared_null\'

etc etc

I can\'t see why. I changed LINK to g++ in the Makefile although that doesn\'t affect the linking as far as QPE is concerned.

Any suggestions gratefully received,

koan
