Subject: Re: caQtDM  Compile Error: qwt_thermo_marker.cpp

Hello Ernesto

You might run into troubles using caqtdm with qwt-6.1.0 on RHEL6 (SL6) especially when you’re using KDE (its a Corba issue if you are interested in the reasons).
==============================================================
I thought it was a multiple inheritance issue based on the warning message
Can you explain this in more detail?
I thought I would never utter the words "CORBA" again.  :(

I attached you the packaging script for caqtdm we currently use here at PSI to create our caqtdm package for SL6 (RHEL6).
You have to adapt the script for sure as it is downloading qwt 6.0.1 for compilation from a local server and cloning the internal git repository for caqtdm. Also the installation path you might want to adapt.
================================================
Here I just downloaded qwt 6.0.1 from Source Forge and build it
Now, everything builds and installs properly

The above only worked for RHEL 6

For Fedora 21;  I can't build qwt 6.0.1
Get the following error:

[ernesto@localhost qwt-6.0.1]$ make
cd src/ && /usr/lib64/qt4/bin/qmake /home/ernesto/tools/Qwt/qwt-6.0.1/src/src.pro -o Makefile
Project ERROR: local build will conflict with /usr/lib64/libqwt.*
Makefile:33: recipe for target 'src/Makefile' failed
make: *** [src/Makefile] Error 2

In any case, we will now start playing with caQtDM under RHEL6 which is what we are using :)

Thanks again.

Cheers,
Ernest

Best
Simon
