can we change the compiler in qmake

[SGaist]

Did you check that you have libz in your sysroot ?

[Asha]

@sgaist ,I checked it in qt kit configuration ,And I am not finding libz in my sysroot..

[Asha]

@pablo-j-rogina Sir,
"beagle@beagle1" is my user name, where my target device name is debian@beaglebone.

I am not successed with make run only,so I am not understood this lines

"You are supposed to only use the BBB device just to copy the cross-compiled Qt libraries and application (which are built in the host machine) and only run it there"

while make running getting error some library files are missing ,Like

"error while loading shared libraries: libz.so.1: /home/beagle1/installQt/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/bin/../libexec/gcc/arm-linux-gnueabihf4.8.2/cc1plus: error while loading shared libraries: libz.so.1: cannot open shared object file:
No such file or directory"....

[Asha]

One more thing ,

SELinux status is Disable in my system,

is this is issue?

[SGaist]

No, the issue is that you don't seem to have zlib available for cross-compilation.

[Asha]

Hi,

can you please tell me,how to install zlib or what is next procedure to do?

[SGaist]

Before starting anything, do you have good reasons to use such an old version of Qt and linaro toolchain ?

[Asha]

Hi,

qt old version is problem?if so,

now I am trying with qt 5.7.1,I downloaded qt 5.7.1 source code and arm-linux-gnueabihf-gcc 6.5.0.

And did some changes in qmake.conf file as said in this link https://forum.qt.io/topic/52546/tuto-build-qt-to-cross-compile-for-arm/47.

where I am finding my qmake.conf file in this path "/home/beagle1/Downloads/qt-everyehere-src-5.7.1/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf"(not finding qws directory as shown in the above link).

So, now I want to configure,but in the link they specified path " ./configure -opensource -confirm-license -prefix /usr/local/Qt-4.8.5-arm -embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++",

I am not getting specially this part "embedded arm -little-endian -no-pch -xplatform qws/linux-arm-gnueabi-g++" what it does?

How can i configure? if I just give "./configure " its configuring linux-g++ ,I want to configure with arm-linux-gnueabihf-g++.

If I give ./configure -opensource -confirm-license -prefix /usr/local/Qt-5.7.1-arm -embedded arm -little-endian -no-pch -xplatform /linux-arm-gnueabi-g++",

then getting error
"invalid command-line switch
arm:unknown argument"..

not getting how do I configure...

Hi,

any suggestions..

[SGaist]

Two:

• don't start with an outdated version of a framework
• follow a guide that targets the current version of Qt

You are following direction for Qt 4 while using Qt 5. There have been a lot of changes in between.

any suggestions..

please check this guide generously written and share by @Ketank16 who is able to cross-compile Qt for the BBB device

[Asha]

@pablo-j-rogina Thankyou for the replay,I will go through it..

[Asha]

@Pablo-J-Rogina Hi,

I followed that document, and I cross compiled qt for beagleboneboard..(done successfully).

when i am running the application ,got the error "could not find the qt platform plugin eglfs"

I searched ,and got the solution,first I need to deploy it on target..

here is the attachement ,I followed

I inserted the line "target.path = $$[analogclock]/bin
INSTALLS += target"
in my .pro file,

After this running the application but getting the error

"rsync error:some files/attrs were not transferred
rsync failed with exit code 23
deploy step failed
Error while building/deploying project analogclock(kit : BBB)
when executing step "deploy files via rsync"

Any suggestions please please...

[Asha]

I want to know how to set the target.path?

[Pablo J. Rogina]

@Asha please check response on this other post also from you

PS: it'd be a good idea if you could stop double posting...
