Qwt Cross-Compile to Arm

Message 1 in thread

    Hi!

   I am new on Qt and I need to know how to cross-compile a qwt program to
arm plataform.

   I am using the qwt to plot a graph and it's work fine on PC plataform.
But I don't know how to compile to arm.

   My other program without qwt (only with qt) are working on arm plataform.

   Some body can teach me how to compile a qwt program using the
arm-linux-gcc?

   Thank you very much!

You could check out the documentation. For version 4.2: 
http://doc.trolltech.com/4.2/qtopiacore-crosscompiling.html.

If you're lucky it's just a matter of configuring Qtopia Core / Qt/Embedded 
with configure -embedded arm.

   I have a program in embedded Linux using Qt. I can compile and run this
program on my arm plataform.

   When I use a QWT lib (qwt.sourceforge.net) in my program, I don't know
how to cross-compile it to arm plataform.

   I think that I need to re-compile the qwt lib to arm plataform with the
arm-linux-gcc compiler, but I don't know how too.

   That's it.

    Thank's.

Use your cross-compiled Qt library:
cd <path-to-qwt>
<path-to-qtopia-core-compiled-for-arm>/bin/qmake
make

Try using the arm toolchain that comes with many distros or download and use crosstool.
