At the moment this is done in the simple way that qmake is called from the configure script.
Since there is not really a straightforward way to look for Qt installations at certain paths,
the automatic determination of the available Qt version is only done through pkg-config.
In case Qt is found at non-standard installation paths, one can either use the configure options
"--with-qt3" or "--with-qt4" to specify the Qt directory or alternatively set the variable
PKG_CONFIG_PATH to some value like
/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:$ROOTSYS/lib/pkgconfig:/opt/qtsdk-2010.02/qt/lib/pkgconfig
During the installation only one editor---either musredit or musrgui---is built and installed.
musredit/Qt4 is generally preferred over musrgui/Qt3.
The only way to install musrgui when also a sufficent Qt4 installation is present is to specify solely
the "--with-qt3" option on the configure level. If additionally the "--with-qt4" option is given, only
musredit will be installed.
Both editors still can be installed as previously---this step is merely to make the installation more
convenient for less-experienced users (hopefully).
* musredit can now be built using Qt 4.5.3 of Cygwin 1.7---however, without online help
* FFTW3 threading in some user functions has been disabled
Obviously, there is a major problem when running musrgui/musredit with Cygwin on Windows7/64bit.
This has not been solved by this commit!
It should now be possible to build a static version of musrfit and shared libraries for the user functions.
This is needed on systems which do not support linking static libraries to shared ones (like Cygwin).
These changes still need to be tested on Cygwin, especially with user functions implementing the "global interface".
Therefore, a new library is built and the plugins link to that one.
This new library at the moment only contains the startup handler, however, finally it might serve as well for other routines
that are used by different plugins.
ROOT is anyway checking multiple extensions for dynamic libraries, therefore leaving them out yields platform-independent msr files.
- Minor changes in libTFitPofB
- Added a user function for Uemura's ZF/LF dynamical spin-glass relaxation function
see, e.g. Y.J. Uemura et al., Phys. Rev. B 31, 546-563 (1985)
or Y.J. Uemura, Hyperfine Interact. 8, 739 (1981)
This yields an overall Lorentzian field distribution with motional narrowing.
However, the present implementation is at best some design study:
The Lorentzian distribution of width "a" is modeled by Gaussian distributions of widths "sigma" from 0 to infinity.
Some "resonable cut-offs" would be: 0.1*a < sigma < 10000*a
Due to finite memory and computing power, in the present version these cut-offs are: 0.1*a < sigma < 40*a
This yields depolarization functions overall similar to those in Uemura's articles.
However, due to the low cut-off the first derivative of the depolarization function is zero in the limit t->0
(what should not be the case for a true Lorentzan).
Furthermore, the calculation is rather slow and the resulting functions should only be regarded as crude approximations.
Therefore, at the moment this is far from being of practical use in analyzing experimental data.
