hello, I would like to use kdevelop with Qt and ruby with a mandriva 2009. so I downloaded kdevelop from the mandriva packages, it runs fine. then, I installed Qt, and ruby.ok. then, I had to install the binding Qt-kdevelop, referring at these pages: - [[www.bawet.org](http://www.bawet.org)] (in french) - [[techbase.kde.org](http://techbase.kde.org)] - [[rubyforge.org](http://rubyforge.org)] finally. in the last page, I have only to install the 2 last packages I think. so I installed qt4-qtruby, I installed smoke (./configure,make, make install) (ok) then I have this error, while trying to install qt4-qtruby: * * * [root@localhost qt4-qtruby-2.0.3]# cmake -DCMAKE\_INSTALL\_PREFIX=/opt/kde4/ . && make && make install – Found Qt-Version 4.5.0 (using /usr/bin/qmake) – Ruby found: /usr/lib/libruby.so – Build Smoke… yes - Qt, QtWebKit, QtScript, QtUiTools, QtTest – Ruby found: /usr/lib/libruby.so – Build QtRuby… yes – Build QtWebKit Ruby… yes – Build QtUiTools Ruby… yes – Build QtScript… yes – Build QtTest… yes – Build QScintilla Ruby… no – Build Qwt Ruby… no CMake Warning (dev) in CMakeLists.txt: No cmake\_minimum\_required command is present. A line of code such as cmake\_minimum\_required(VERSION 2.6) should be added at the top of the file. The version specified may be lower if you wish to support older CMake versions for this project.

Add code such as if(COMMAND cmake\_policy) cmake\_policy(SET CMP0003 NEW) endif(COMMAND cmake\_policy) as early as possible but after the most recent call to cmake\_minimum\_required or cmake\_policy(VERSION). This warning appears because target “smokeqtwebkit” links to some libraries for which the linker must search: -lpthread and other libraries with known full path: /home/lolveley/bin/qt4-qtruby-2.0.3/smoke/qt/libsmokeqt.so.2.0.0 CMake is adding directories in the second list to the linker search path in case they are needed to find libraries from the first list (for backwards compatibility with CMake 2.4). Set policy CMP0003 to OLD or NEW to enable or disable this behavior explicitly. Run “cmake --help-policy CMP0003” for more information. This warning is for project developers. Use -Wno-dev to suppress it. – Generating done – Build files have been written to: /home/lolveley/bin/qt4-qtruby-2.0.3 [35%] Built target smokeqt [40%] Built target smokeqtwebkit [45%] Built target smokeqtscript [50%] Built target smokeqtuitools [54%] Built target smokeqttest [59%] Built target qtruby4shared [61%] Built target qtruby4 [83%] Built target rbuic4\_bin [87%] Built target rbrcc [90%] Built target rubyqtwebkit [93%] Built target rubyqtuitools [96%] Built target qtscript Linking CXX shared module qttest.so /usr/bin/ld: cannot find -lsmokekde collect2: ld a retourné 1 code d’état d’exécution make[2]: \*\*\* [ruby/qttest/qttest.so] Erreur 1 make[1]: \*\*\* [ruby/qttest/CMakeFiles/qttest.dir/all] Erreur 2 make: \*\*\* [all] Erreur 2 * * * can you help me? olivier. ---

Also, if you installed smoke using ./configure, make, make install, you installed the qt3 version of smoke, while the version of qtruby you want to install is for qt4. So: what version of Qt do you wish to use? If you want to use qt4, you’ll simply need the qt4-qtruby-2.0.3.tgz file from [http://rubyforge.org/frs/?group\_id=181&release\_id=32620](http://rubyforge.org/frs/?group_id=181&release_id=32620) then do the following: tar -xf qt4-qtruby-2.0.3.tgz mkdir build cd build cmake -DCMAKE\_INSTALL\_PREFIX=/opt/kde4 …/qt4-qtruby-2.0.3 make sudo make install This should work. As I said, you don’t need to install smoke separately. Since you seem to have done that, I suggest that you uninstall it, before doing the above. I hope this helps Stefano ---

hello, thx for having answered to my question. I want to use Qt4, eg without smoke if I have well understood you. I will have to stop this installation due to problems with my graphic card, but I will retry as soon as possible. anyway, do you know the steps after having qt4-qtruby installed to have kdevelop working with ruby and qt (notably having qtdesigner work in kdevelop)? olivier. ---

Well, I don’t think you need to do anything special to have kdevelop work with ruby. If it was compiled with ruby support enabled, you should see some ruby projects templates when you choose the Project/new menu entry. If you don’t see it, chances are that you need to compile it by hand enabling ruby support. The qt designer should work with kdevelop without any special configuration, unless you want to use kdevelop 3 with Qt4. In that case, I’m afraid you’ll need to run the designer as a stand-alone program. Stefano ---
