    oh, sorry :) I was focused only on the .pro syntax, not even looked on the lib names :)

      do not use '' at the end when not breaking the line

      If I don't use the '' the Qt show me error ("library ...lqjson not found").

        mitchelhajime, no mater you do, you won't compile this project on ubuntu. Also it seems you just don't have the qjson lib.

          :/ I installed qjson with ubuntu's repository... Is better I download the library and compile in terminal or Qt?

            That's fine, you just need to check where it is and pass the correct path.

            But still, I think you've missed this:

                If you really want to cross-compile the project, you should compile the Qt using the cross-compiler first. All of course, you will come with many many problems, but once done, you will be a Specialist in Qt area.

                However, I don't know: what is the project for? why you want to compile a windows project under linux? ....

                  It is a program that talks to a hardware to get and send data with interface (for the customers).
                  I need to make this run in linux and windows. :/

                  Thanks for help I go to read about Cross-Compiling now :)

                    ;(

                    You are on the wrong way now, you should know that, the result of cross-compiling is a windows application. After successfully(If you really can do this) compiled, you will need a windows system to run it!

                    If all you use is a serial port, it will be very easy.

                    Forget this .pro file, write a right one.

                      I agree it's pretty easy to make a program that configures the hardware and send (for one website) and receive data (for sensors) , but I need to do with with graphical interface and linux for end user.

                        What I mean is, write a cross-platform serialport application with GUI is rather easy too.

                        But you have make an easy problem become complexed, as you get a platform special project file, and you want to compile it under another platform.

                        Cross-platform examples can be found from google too. such as

                        http://docs.qextserialport.googlecode.com/hg/1.2/examples-uartassistant.html

                          Thanks after I used part of this lib's example for made the project but I had to add a timer and a customizable filter for the output data.
