QtFtp and Qt5.3.1 on imx6 undefined reference

healthhazard

Hi,

I'm trying to port a large embedded application from Windows and Qt4 to Linux and Qt5.3.1 on imx6.

Initially i thought that qftp compiled successfully, but when i run a 'make clean' and try to recompile it now even the included examples fail with the same undefined references as my application:

maybe there is something in the wrong place or something is not configured correctly?

I tried the syncqt.pl with version 5.3.1 (Qt version) as well as 5.0.0, which seems to be the qftp version. Do I need to specify something else in this step?

Any help is appreciated!

Thanks in advance,

make clean is usually not enough when compiling Qt modules. Try a fresh code checkout (delete the directory, extract again/ git clone again).

healthhazard

okay, the following did the trick, I think. Thank you very much!

@rm -rf qtftp
git clone git://gitorious.org/qt/qtftp.git
cd qtftp
/opt/qt5-imx6/bin/syncqt.pl -version 5.3.1
qmake
make@

my problem was the missing sync and then I forgot to try a fresh checkout as I already tried before (without sync)...

now, there are only some application internal undefined references left in my application ;)

Nice. Happy coding :-)
