Qt5 for imx6
-
Hi. I'm trying to cross-compile Qt 5.12.0, but compilation was excepted with message:
In file included from ../../../include/QtCore/qglobal.h:1:0, from ../../../mkspecs/linux-g++/qplatformdefs.h:45, from ../../corelib/io/qfsfileengine_p.h:54, from ../../corelib/io/qfsfileengine.cpp:41: ../../../include/QtCore/../../src/corelib/global/qglobal.h:121:49: error: static assertion failed: Unsupported: read/write return a type with different size as the len parameter # define Q_STATIC_ASSERT_X(Condition, Message) static_assert(bool(Condition), Message) ^ ../../corelib/io/qfsfileengine.cpp:88:1: note: in expansion of macro ‘Q_STATIC_ASSERT_X’ Q_STATIC_ASSERT_X(sizeof(SignedIOType) == sizeof(UnsignedIOType),here is my config parameters:

Thanks! -
Hi,
What version of gcc are you using to build Qt ?
-
@SGaist I tried just now another toolchain: gcc-arm-none-eabi-7-2018-q2-update
But I had got excepted configuration process:> /home/eugene/qt5/cache/gcc-arm-none-eabi-7-2018-q2-update/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/lib/hard/libc.a(lib_a-exit.o): In function `exit': > exit.c:(.text.exit+0x2c): undefined reference to `_exit'I tried to do workaround:
export QMAKE_LFLAGS="--specs=nosys.specs"but without success (nothing changes)
-
At which point do you get that error ?
-
@SGaist Well, I removed and deleted all packages and arm-toolchains. Then I did install toolchain, again: sudo apt install g++-miltilib-arm-linux-gnueabi, and it solved configuration process.
But the topic (excepted compilation) is still yet:

It seems you are back to an older version of gcc. Do I see correctly ?
-
@SGaist No, from beginning I tried to use this version. I don't know, maybe it is older version, but this is the current version in Ubuntu 16.04 (or Mint 18.3) repos
@SGaist Finally I got latest compiler:

@SGaist Seems that I have got a success with it. All manuals which I read (included nxp forum) told me about *-gnueabi compiler, but I tried to compile Qt for device imx6 with gcc-arm-8.2-2018.11-x86_64-arm-linux-gnueabihf (hard float). As result configuration and compilation was done without troubles.

Glad you succeeded and thanks for sharing !
Any chances that you had a sysroot that was mismatching with your compiler ?

@SGaist Well, I think no (if I understand your question right), because all paths to the compiler was setted right. Currently I'm trying to do a clean sysroot on my PC x86_64 (just a Qt+glib+gstreamer) with needed libraries (one question with pkg-config and Qt no resolved for me, yet) for the cross-compilation of target apps. As result I will produce a bash-script for a building an arm-sandbox to cross-compile from x86-64 machine to the ARM (specially imx6) and publish it here.
Also thank you for your leading questions (because really currently available in the Ubuntu repos version of compiler is deprecated, I think)!
