The "example" program : Link problems

[jdf]

This is my 2nd attempt to try to install the tools for developing for the 5500.

I followed the development \"HOW TO\" exactly for configuring the compiler and loading Qt for embedix.  However, when I run make, it seems to work at first using gcc296 and then the messages start flying about undefined objects. Thousands of messages!  

In any case I am new to Linux.  I can follow instructions.  I am using Fedorar Core and I also loaded the \"compat-****\" files to get the compatible gcc.

If you have already done this, please look at the \"How to\" for compiler setup and and see if you remember any trick you needed to get it going.

Thankx John

More info about MY QUESTION ABOVE!

This is the command that make runs:
gcc296  -o example main.o example.o examplebase.o moc_example.o moc_examplebase.o  -L/opt/Qtopia/lib -lqpe -lqte

These are the first couple error messages when I run make:

main.o(.text+0x1d): In function `main\':
: undefined reference to `QPEApplication::QPEApplication(int&, char**, QApplication::Type)\'
main.o(.text+0x3e): In function `main\':
: undefined reference to `QPEApplication::showMainWidget(QWidget*, bool)\'
main.o(.text+0x46): In function `main\':
: undefined reference to `QPEApplication::exec()\'
main.o(.text+0x59): In function `main\':
: undefined reference to `QPEApplication::~QPEApplication()\'

followed by hundreds more!!!!

THANKX FOR ANY HELP OR HINTS YOU CAN PROVIDE!!

[markb]

I just tried building the example, and it worked for me.
I\'ll post what I did below in case it\'s of any use to you.

I run the environment setup script.
Copy the application directory from the examples directory.
Use tmake to create the Makefile.
Then run make.

I hope this helps.

[jdf]

markb...Thankx a lot for answering quickly.  encourafged me to keep trying.

I have reached success too!!

THIS IS WHAT I THINK THE PROBLEM WAS:

HOWTO step 2 says download the free Qtopia
     qtopia-free-1.5.0-1.i386.rpm

I did that and got a lot of errors.  I then found at another source a suggestion to change the tmake.conf file so that it uses the 2.96 compiler.  I did that to.

That installation resulted in the original questions.

CURRENT configuration.
1) removed qtopia-free-1.5.0-1.i386.rpm
2) installed from trolltech the latest : qtopia-free-1.7.0-2rh9.i386.rpm
3) DON\'t use a different tmake, use as provided in the updated rpm.
4) Then from my home directory did these commands:
 source ./dev-x86-qpe.sh
 cp -r /opt/Qtopia/examples/application/ .
     (had some permission problems that I needed to fix before copying)
 cd application
 tmake -o Makefile example.pro
 make

5) Everything went FINE.  exactly like your listing above, opened the frame buffer and executed the command. SUCCESS!!

Now my question to be found out as I experiment more:  What was all the issues about having to use the 2.96 versions of compiler?  It looks like my success is based on NOT using the gcc296!!!  Am I going to be up against that when I cross-compile for the zaurus?

Thakx so much for givng encouragement to us exitied newbies!

John

[markb]

I\'m glad you got it working!
I\'m not sure what the issue with the compiler version is.
I\'m using RH8.0 so didn\'t pay any attention to that bit in the HOWTO for SuSE users.

I seem to have version 3.2

I did some cross-compilation last year for my SL-5000D, but that was on an old computer. I haven\'t set it up on this computer yet.
I have that joy to look forward to. :-)
(But from what I remember it wasn\'t too tricky to set up.)

I\'m waiting for my C860 to arrive, hopefully next week, then I\'ll get stuck in and have a go.

- I think the older version of qtopia, the one you're no longer using, jdf, requires the older compiler.  Mine got the same linker errors you experienced until I cottoned onto the fact that I hadn't updated tmake.conf yet.  (drool)  After that, no problems at all.
