QtSerialPort build problem (Linux, Debian, Qt4)
-
Hi There.
I recently purged my machine and now I am trying to get QtSerialPort to work again with Qt4.
I fetched Qtserialport from git:
@git clone git://gitorious.org/qt/qtserialport.git@Moved it into a seperate src folder:
@
10034 ./opt % mv qtserialport qtserialport-src
10035 ./opt % mkdir qtserialport-build
10036 ./opt % cd qtserialport-build
@
And tried to build it. However it cannot find a file that should be included.
@
10037 qtserialport-build % qmake ../qtserialport-src
debian ~/.opt/QtSerialPort/qtserialport-build
10038 qtserialport-build % make
.
.
.
In file included from /home/f/.opt/QtSerialPort/qtserialport-src/src/serialport/qserialport_unix_p.h:46:0,
from /home/f/.opt/QtSerialPort/qtserialport-src/src/serialport/qserialport.cpp:53:
/home/f/.opt/QtSerialPort/qtserialport-src/src/serialport/qserialport_p.h:49:35: fatal error: private/qringbuffer_p.h: No such file or directory
compilation terminated.
make[2]: *** [qserialport.o] Error 1@From gitk i can see, that a version-check-macro was removed:
@
------------------------ src/serialport/qserialport_p.h ------------------------

#include <private/qringbuffer_p.h>

@And now I have no idea how to fix this.
Should i just hardcode the correct include path? (Since the file is there....)
Any ideas? -
Try pinging QtSerialPort maintainers, they are usually quick to reply. Maybe this can be fixed upstream.
You can modify the path yourself, of course. This is Free Software, after all :)

Hi.
What version of Qt4 is used in Debian?
BTW:
A file "qringbuffer_p.h" contains in "src\serialport\qt4support\include\private" directory. So, at process of building for Qt4 this file always takes from this directory.
The path to this directory is specified in the "install-helper.pri" file. Thus, it is possible that the QTSERIALPORT_PROJECT_QT4SUPPORT_INCLUDEDIR variable is empty in your case. Check it.

I just did this :)
In the current stable version of debian (as of today -- wheezy) it is 4.8.
It seems like the variable is set but the path is never executed on my system, which means that the check :
@45: lessThan(QT_MAJOR_VERSION, 5) {...@
is failing on my system.But problem solved anyhow :)
Thanks for your replies -
Ok, But also you can build library through QtCreator, see "this":http://qt-project.org/wiki/QtSerialPort#e290b0f84383a96ecdf7f6b720b72092.
Maybe a problem in ENV? Have you installed and Qt5 (i.e. have you both: Qt4 and Qt5 on your system)?

As the author of those changes, I have just made some experiments to see this a bit closer. I have used the "stable" branch for it.
Unfortunately, I cannot reproduce the issue on my Archlinux (updated this morning) with 4.8.5.
I also tried my Debian Wheezy (7.0) with 4.8.2, but I have similar results. It works fine for me.
I think you had some local troubles that you could probably share with us if you had fixed it? Others could learn out of it.

Hello,
You need to install this:
sudo apt-get install qtbase5-private-dev
