Hi Mark, Emmanuel and all,

Thanks for your help, finally I made it. I'd like to share my experience.

I think the previous failed reason was:

1: On my linux system (Linux Mint Qiana, x86_64, kernel 3.13.0) Qt 4.8.6

(/usr/lib/x86_64-linux-gnu/qt4) and 5.1.1

(/opt/Android/Qt5.1.1/5.1.1/gcc_64/) was installed;

2: The 'qmake' command (/usr/bin/qmake) is 4.8.6 by default, which would

be called first before I redefined the PATH value;

Thanks to Mark and Emmanuel's message, I clearly redefined the PATH

value to let 'qmake' be definitely the 5.1.1 version, i.e.

export

PATH=PATH=/opt/Android/Qt5.1.1/5.1.1/gcc_64/bin:/bin/:/usr/bin/:/usr/sbin,

and then everything went smoothly.

Regards,

Tong

I had similar problems the other day when I built caQtDM on Linux.
Anton helped me a lot.

I have appended a message that includes the complete trail of
communications with Anton.  I have also attached a shell script I
created to define all of the necessary environment variables.

I think my most important 2 mistakes were:

- Not defining QTBASE, which I then defined as:

QTBASE=/usr/local/caQtDM/3-8-5/caQtDM_Binaries

- Not using the top-level build script, caQtDM_BuildAll.  I was just
using qmake and make, which did not work.

Tong Zhang,

I can certainly help you.
Difficult to say what exactly is the problem without the error message.
To start, I would just guess that you environment is not set correctly.
Are you on Linux?

Note that  QtDM requires a few environment variables to be set to start
and run correctly.
What are your settings for QTDM_LIBINSTALL, QTDM_RPATH, and LD_LIBRARY_PATH?
In the tutorial you are following, my installation paths were

/home/local/epics                # Home directory of the epics user

+-- base

     +-- <base.version>           # Base version is 3.14.12.4

         +-- bin/linux-x86_64

         +-- lib/linux-x86_64

+-- extensions

     +-- <base.version>           # Extensions compiled against this base version

         +-- src                  # Where the source for EPICS extensions is installed

         +-- bin/linux-x86_64     # Where the extension binary files are installed

         +-- lib/linux-x86_64

+-- extras                       # Non-EPICS base and non-EPICS extensions

     +-- <base.version>           # Version the source was compiled against

         +-- bin/linux-x86_64     # Where the binary files are installed

         +-- lib/linux-x86_64

In the tutorial, I installed caQtDM in the extras/... directories as it is not
an EPICS extension (i.e. doesn't use the configure directory which is part of
the EPICS build system)

I hope this help.

If it doesn't, send the error message and the first few lines of
./caQtDM_BuildAll

Subject: compile qtdm

Hi Emayssat,

I came cross your caQtDM wiki page, it is really a great job. I'm
working on the development for FEL facility control applications, and I
have experience about C++/QT, so your qtdm is a nice tool for me to
choose. However, I failed to compile the source, is complains the
qtcontrols lib when linking, my qt version is 4.8.6, could you please
help me out?

Thanks!
