    @MhM93 You built it for X86 not for ARM...

      but I do this with my compiler path

      export PATH=/usr/local/arm/4.7.0/bin:$PATH
      export CROSS_COMPILE=arm-none-linux-gnueabi-
      export CC=${CROSS_COMPILE}gcc
      export CFLAGS=-march=armv7l
      export CXX=${CROSS_COMPILE}"g++" 
      export AR=${CROSS_COMPILE}"ar" 
      export AS=${CROSS_COMPILE}"as"
      export RANLIB=${CROSS_COMPILE}"ranlib"
      export LD=${CROSS_COMPILE}"ld"
      export STRIP=${CROSS_COMPILE}"strip"
      export ac_cv_func_malloc_0_nonnull=yes

        Check the configure script options. There's something like --host=arm-none-linux-gnueabi IIRC.

          really thanksssssssssssssssssssssssssss
          It compile without error with this command, at last.

          sudo ./configure --host=arm-none-linux-gnueabihf --prefix=/home/tslib --enable-shared=yes --enable-static=no
          

          but when I copy the exe file to my arm device it again show me this error:

            @MhM93 said in my cross compiler has error.tslib install but has error:

            [1]+ Segmentation fault ./helloqt -qws

            This is another problem. Try to start your app in a debugger to see what happens.
            Also why do you start it twice:

            root@NanoPC-T2:/# ./helloqt -qws &
            [1] 1409
            root@NanoPC-T2:/# ./helloqt -qws
            

            ?

              I do not install qt creator to see debug mood in my pc, and also this program is run on nanopc-t2 when I wrote this command it returns :

              execve("./helloqt", ["./helloqt"], [/* 20 vars */]) = 0

              Segmentation fault
              

              Also why do you start it twice:
              with silly reason. I just test what happen to run command with & and without it. :)

                @MhM93 You don't need to install QtCreator to debug (QtCreator itself does not have a debugger). Just install gdb on your target device and use it. It looks like your app is running except you try to run two instances at the same time.

                      Again, run it through the debugger.

                      By the way, what is the exact architecture of your device ?
                      What Linux distribution are you running on it ?

                        thanks for reply,
                        I should install debugger on my host or on my target?
                        this is my device:

                        root@NanoPC-T2:/# uname -a
                        Linux NanoPC-T2 3.4.39-s5p4418 #1 SMP PREEMPT Wed Mar 1 13:21:10 HKT 2017 armv7l armv7l armv7l GNU/Linux
                        

                        when I run gdb on my device (nanopc-t2):

                        root@NanoPC-T2:/# gdb -q helloqt
                        "/helloqt": not in executable format: File truncated
                        

                        and also when I run this:

                        root@NanoPC-T2:/# sudo readelf -a ./helloqt | grep NEEDED
                        readelf: Error: Reading 0x618 bytes extends past end of file for section headers
                        readelf: Error: Section headers are not available!
                         0x00000001 (NEEDED)
                        

                        Is that mean my header is wrong?
                        this is my code:

                        #include <QApplication>
                        #include <QPushButton>
                        int main(int argc, char **argv)
                        {
                                QApplication app (argc, argv);
                                QPushButton button ("Hello world !");
                                button.show();
                                return app.exec();
                        }

                          Looks like there is a problem with your file. How are you copying it over to your device ?

                            tftp 192.168.101.4
                            tftp>get helloqt
                            //after transfering.....
                            tftp>quit
                            

                            first run this command

                            . setqt4env
                            

                            and after that run this command, I make my file runable with this command:

                            chmod +x helloqt
                            

                            then I run it with this command but that error show to me:

                            ./helloqt -qws
                            

                            ................................................................................................................................................................................
                            FINALLY RUN MY APP ON ME DEVICE BUT MAKE A LOT OF QUESTION FOR ME:
                            .............................................................................................................................................................................
                            I set my ssh to deploy the qt (from vmware ubuntu to my nanopc) also set this to .pro file:

                            #-------------------------------------------------
                            #

                            #-------------------------------------------------
                            
                            QT       += core gui
                            
                            greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
                            
                            target.path = ~/helloqt
                            INSTALLS += target
                            
                            TARGET =
                            TEMPLATE = app
                            
                            
                            SOURCES += main.cpp\
                                   mainwindow.cpp
                            
                            HEADERS  += mainwindow.h
                            
                            FORMS    += mainwindow.ui
                            

                            and set -qws in argument and suddenly see the project run on my device BUT the touch is not worked
                            when I copy the file to my device as I said above* the app is can not run. what is the different from my code runable and qt runable app?

                              Why don't you upload it directly to your device ?
                              Using e.g. scp ?

                                    sorry At first I searched it, but I found this:

                                    SCP Foundation
                                    From Wikipedia, the free encyclopedia

(SCP stands for "Special Containment Procedures", though it also refers to the organization's slogan of "Secure, Contain, Protect".) The stories generated by the project describe the exploits of the Foundation, supposedly responsible for containing individuals, entities, locations, and objects that violate natural law (referred to as SCPs). The main written works on the SCP Foundation website are articles written in the style of structured internal documentation about the contained SCPs.

                                    and I confused what is SCP, sorry for silly ask, excuse me,thanks for secure copy @jsulm and @SGaist
                                    thanks for all help
                                    thanks a lot with best wishes for you

                                        Why sudo ? There's no reason to configure nor compile as root.
