Qt 5.5 - i.mx27 - building for cross compiles

[Benoit GB]

Hi, I need good practice help for configuring and compiling Qt .
Context :
Host platform : linux x86 (ubuntu 15.10)
target platform : linux arm (i.mx27)
target SD copy : ~/Développement/Linux-Embedded/i.mx27_SD (bin+ *.so)
toolchain :/opt/OSELAS.Toolchain-1.99.3/arm-v4t-linux-gnueabi/...
Qt source : ~/Developpement/qt-everywhere-opensource-src-5.5.0/
personal adds : ../mkspec/linux-arm-v4t-gnueabi-g++/ (copy of "linux-arm-gnueabi-g++" with arm-v4t-gnueabi banaries references)

I try set the suitable "configure" command line but it failed..

Hi and welcome to devnet,

That's a bit vague, can you please elaborate a bit what you are asking for ?

[Benoit GB]

@SGaist i updated the original post

[Benoit GB]

I manged tout build qt 4.5 for embedded i.mx27 before. But today it fail with qt 5.5 ans new "configuré" paramètres.
So i have few conected question:

• Do we need "sysroot" paramétrer ?
• What configuré can get in "RootFS" ? Include files? Lib files?
• i have libpng.so,libjpeg.so files for arm in /usr/lib/arm-linux-gnu on host machine : are these libs usefull ?
• do qt need extra include or lib files for third-party? If yes , howto référence then to "configure" ?

[SGaist]

1. No you don't, but in this case, you will need to provide Qt's dependencies by hand
2. configure will find there the dependencies for e.g. OpenGL, SQL drivers etc.
3. Depends on whether you want to use Qt's provided libraries or not
4. That depends on what feature you want to build. It's shown in configure --help

[Benoit GB]

OK , thank's
i understood things in a better way . And "make" operation proceeded in the good way

[SGaist]

You're welcome !
