[SOLVED] Qt5 adding mkspecs

ltillier

Hello everybody

I would like to create a graphic interface on a embedded linux with an ARM architecture using Qt.
So I downloaded the source code of Qt5 (the tar.gz for Linux).
I have extracted the files.

Before running ./configure with the correct configuration options, I have to add in the qtbase/mkspecs/ directory the configuration of my toolchain. And I think this where I'm wrong.

I created in /mkspecs directory a new directory "arm-v5t-g++" with the name of my toolchain, that is quite similar to linux-arm-gnueabi-g++
And in that new folder I have created a qmake.conf and qplatformdefs.h file.
The qplatformdefs is the same as the one of linux-arm-gnueabi-g++.

Here is the qmake.conf

MAKEFILE_GENERATOR      = UNIX
CONFIG                  += incremental gdb_dwarf_index
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

# modifications to g++.conf
QMAKE_CC                = arm-v5t-gcc
QMAKE_CXX               = arm-v5t-gcc
QMAKE_LINK              = arm-v5t-gcc
QMAKE_LINK_SHLIB        = arm-v5t-gcc

QMAKE_INCDIR  =/home/arm/v5t/target/usr/include
QMAKE_LIBDIR  =/home/arm/v5t/target/usr/lib

QMAKE_LIBS              = -lpng

# modifications to linux.conf
QMAKE_AR                = arm-v5t-ar cqs
QMAKE_OBJCOPY           = arm-v5t-objcopy
QMAKE_STRIP             = arm-v5t-strip

load(qt_config)

And then I run ./configure -xplatform linux-arm ...

But I have got errors
/home/Qt5/qt-everywhere-opensource-src-5.0.1/qtbase/configure: line 2638: arm-v5t-g++: command not found

May someone helps me ?
I don't know where I have made a mistake and I can not find help for embedded system with Qt5.

Thanks you

Hi,
I think that your arm-v5t-g++ is not in your PATH so it can't be called. You need to update your PATH (perhaps inside your bashrc/profile etc...)

Hope it helps

Thanks you for your advice. That worked out !

But I got a new error when I run the ./confgiure ...options...

@
arm-v5t-g++ -o libtest.so -shared -Wl,-Bsymbolic-functions -fPIC bsymbolic_functions.c
/free/montavista/pro/devkit/arm/v5t_le/bin/../lib/gcc/armv5tl-montavista-linuxeabi/3.4.3/../../../../armv5tl-montavista-linuxeabi/bin/ld: unrecognized option '-Bsymbolic-functions'
@

Regarding the --help of arm-v5t-g++, the syntax seems good
@-Wl,<options> Pass comma-separated <options> on to the linker@

I can't figure out from where comes that issue.

SGaist

At first sight, I would say the age of your compiler (3.4.3 is around 7 years old).

You should get a recent cross-compiler (gcc is currently at 4.7.2 and the oldest maintained version is 4.6.3)

Ok and is there anyway to disable Bsymbolic functions with the configure options ?

SGaist

The minimal arm gcc for Qt4.8 is already 4.1.1. I don't know yet for Qt5, so 3.4.3 won't be able to compile Qt5.

Ok thanks for your help
