With the pending release of Qt4 very soon, I wanted to take a moment to update |
| 2 |
the community on what kind of effect it will have on portage: |
| 3 |
|
| 4 |
First, the installation is now FHS compliant - no more stuff going |
| 5 |
into /usr/qt. |
| 6 |
|
| 7 |
Previous Qt versions built one big library; this version builds 9 or 10 |
| 8 |
smaller ones (all installed into /usr/lib/qt4). Since the names are |
| 9 |
different, as well as the sonames, there should not be any runtime linking |
| 10 |
issues with a mixed installation. |
| 11 |
|
| 12 |
Qt4 does not make use of the QTDIR environment variable like Qt3 did. This |
| 13 |
means that automated build scripts, such as those with most KDE programs, |
| 14 |
will still pick up the correct Qt3 programs (uic, moc, and qmake). For |
| 15 |
programs that don't use these types of build scripts, ebuild modifications |
| 16 |
may need to be made to tell the package which directory to pick up its binary |
| 17 |
tools in (/usr/qt/3/bin for Qt3, /usr/bin for Qt4). |
| 18 |
|
| 19 |
I currently don't have any plans for any type of xxx-config package to switch |
| 20 |
between versions. After installing Qt4, those applications will be higher in |
| 21 |
precedence in the PATH. If you need to run Qt3 applications, you will either |
| 22 |
need to specify the full path or restructure your PATH to make it work. |
| 23 |
|
| 24 |
Even though Trolltech split out the GUI libraries from the rest of the core |
| 25 |
libraries, X11 is still a dependency for the whole package. The reason for |
| 26 |
this is that, as of now, Trolltech hasn't provided a convenient way to build |
| 27 |
a subset of the libraries - it's really an all or nothing thing. Eventually |
| 28 |
once the development stabilizes a bit, I think it will be feasible to have a |
| 29 |
gui and non-gui set of ebuilds. |
| 30 |
|
| 31 |
All that said - the latest version in portage ( qt-4.0.0_rc1-r2 ) works and |
| 32 |
installs great for me. At this point, it may be good for aches to try |
| 33 |
testing the installation, as well as people who use non-traditional setups, |
| 34 |
like icc, ulibc, or "interesting" CXXFLAGS. |
| 35 |
|
| 36 |
At the moment, I don't know of any installable applications that make use of |
| 37 |
this new Qt version, but they'll be springing up very soon. Hopefully we'll |
| 38 |
be ready for them. |

Thanks, |
