Error cross compiling Qt library for Raspberry

[Gimq]

I’m having problems correcly cross compiling a Qt library for Rasberry Pi.
I’m using the following setup:

Windows 8.1 64 bit
Visual Studio 2010
VisualGDB 4.1
Latest Raspian wheezy image

I start out by creating a new application, setting the project template to ‘A QT-based application’. I’m doing this since there is no template for Qt in shared library.
Next I select build locally with cross compiler. When the project has been created, I edit the .pro file to set the project template to a library, changing

TEMPLATE = app

to

TEMPLATE = lib

resulting in this .pro file:

#Generated by VisualGDB project wizard.
#Feel free to modify any flags you want
#Visit http://visualgdb.com/makefiles for more details

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = test5
TEMPLATE = lib

SOURCES +=MainWindow.cpp test5.cpp

HEADERS  += MainWindow.h

FORMS    += MainWindow.ui

include($$lower($$join(CONFIGNAME,,,.pro)))

OBJECTS_DIR = $$DESTDIR
MOC_DIR = $$DESTDIR
RCC_DIR = $$DESTDIR
UI_DIR = $$DESTDIR

When I build the project, I’m getting the following output:

So it seems like the ln commands are not working.

Am I approaching this the worng way, overlooking a stupid thing or is there maybe a project template for this somewhere?

Hi,

This looks like a bug in our toolchain. Thanks for reporting it, we will fix it in the next release. In the meanwhile please use the following workaround:
1. Download mv.exe to SysGCCRaspberrybin
2. Modify SysGCCRaspberryarm-linux-gnueabihfsysrootusrshareqt4mkspecsarm-linux-gnueabihfqmake.conf so that QMAKE_MOVE is set to mv:

QMAKE_MOVE				= mv

3. Create a file called ln.bat in SysGCCRaspberry with the following contents:

copy /y %2 %3

[Gimq]

Thanks, that did the trick, except that the ln.bat needs to be in SysGCCRaspberrybin.

A clean build is running ok now. The incremental build is not, I’m getting the following output:

Maybe the problem is that the del command should get a backslash in the path and not a forward slah?

[Gimq]

Created a workaround for the last problem. The problem was indeed the forward slash, so I created a script to replace the forward slash with a backward slash, created the script SysGCCraspberrybindelcmd.bat

@echo off
set filepath=%1
set delcommand=del %filepath:/=%
%delcommand%

Then set the QMake del command to the script in SysGCCraspberryarm-linux-gnueabihfsysrootusrshareqt4mkspecsarm-linux-gnueabihfqmake.conf

QMAKE_DEL_FILE			= delcmd

Now getting this output:

the script is not entirely correct, since the command

delcmd libtest1.so.1.0.0 libtest1.so libtest1.so.1 libtest1.so.1.0

will not delete all files as it processes only 1 argument. I think this is enough for me right now though, but I will fix the script soon to correctly delete all files.

[scp_synaflex]

Did this ever get fixed?

I did the same as Gimq, i.e. created a QT app and then turned it in to a .lib.

I’ve tried following the steps to fix above but the link to mv.exe is broken, is there another link/wesite where I can download it from?

Thanks.
