Cross compiling cpp(gcc-cross-2.95)-QT library not found

[summer00]

i tried to cross compile a program with ./configure script, i have everything necessary installed....

this are the steps i have followed

source dev-arm-qpe.sh
./configure
.
error statement:

....Checking for QT library ...not found
.....giving up

any ideas on thi s? thanks a lot

You need to obtain the QPE SDK from Trolltech (Either the GPL or Commercial edition) depending on which type of software you are developing:

http://www.trolltech.com/download/qtopia/i...ndex.html?cid=6

[summer00]

but i have already installed qtopia-free-1.5.0-1.i386.rpm.....i

Which program are you compiling? Are you sure it looks for the embedded version of Qt ?

[tumnus]

For starters, your configure command needs to be more like this:

CC=arm-linux-gcc ./configure --target=arm-linux

If that still doesn\'t work, then either:

- The Qtopia SDK didn\'t install properly
or
- Something is wrong with your dev-arm-qpe.sh
or
- The configure script isn\'t working properly

Did you follow the cross-compiler howto all the way through, even building the example Qtopia app, just to confirm the toolchain is working?

[summer00]

i tried to execute this :

CC=arm-linux-gcc ./configure --target=arm-linux

here are the results :

loading cache ./config.cache
checking for gcc... arm-linux-gcc
checking whether the C compiler (arm-linux-gcc  ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.

Either you don\'t have gcc configured right or you haven\'t installed the cross compiler rpms?

What version/distro of Linux are you using?

I have built apps using Red Hat 9 and Fedora Core 1.  Haven\'t tried Core 2 yet.

[summer00]

im using redhat 9 kernel 2.4.26, may i know how to configure both c and c++ compilers? thanks

Do you have QT in your library path? Where is your config script looking for QT?

If all else fails, post your configure script.

John

QT ? a file named \"QT\"?

the library path :
file:/opt/Qtopia/sharp/lib    or   file:/opt/Qtopia/lib ?

i run dev-arm-pde.sh before i execute ./configure, could it be the configuration in dev-arm-pde.sh not correct?

Well no, Qtopia itself.

the library path :
file:/opt/Qtopia/sharp/lib    or   file:/opt/Qtopia/lib ?

Good, so where is your ./configure file looking for it?

i run dev-arm-pde.sh before i execute ./configure, could it be the configuration in dev-arm-pde.sh not correct?

Mmmm, maybe. Post it so brighter minds than mine can have a look-see.

i think if this script is executed, then ./configure will follow tha paths above....correct me if im wrong , thanks

[Stubear]

It\'s possible that even with the paths set correctly that configure has been badly set up or is searching for a higher version of QT than the Z uses - have a look in config.log for the exact error - and also the path it is using

seems like it stoped at Qt header files

[zenyatta]

summer00: now you need to look inside configure at line 1141 and find out what exactly it is trying to do when it fails. It will check for the existence of certain files in certain directories. You can then find those files and copy them to the directories where configure is looking.
