| Summary | 0011619: qmake-qt4 not found in 2.8.3 if qmake is from Qt 3 | ||||||||
| Description | On my RHEL4/5 systems, the qmake in the path (and QTDIR) is version 3, so when using Qt 4, qmake-qt4 has to be used. FindQt4.cmake supports this, and it worked in CMake 2.8.2, but it's broken in CMake 2.8.3: CMake Error at /opt/cmake-2.8.3-Linux-i386/share/cmake-2.8/Modules/FindQt4.cmake:1148 (MESSAGE): Qt qmake not found! The problem appears to be line 482: "_qt4_query_qmake(QT_VERSION QTVERSION)". QTVERSION doesn't get set. Compare that to line 385 in 2.8.2, where EXEC_PROGRAM is called on the qmake executable to test the version. | ||||||||

Can you give me the output from cmake when processing this: find_package(Qt4) message(STATUS "qmake=${QT_QMAKE_EXECUTABLE}") |

qmake=/usr/local/qt-3.3.4/bin/qmake-NOTFOUND |

Is qmake-qt4 in your path? |
|
(0024256) Sam Hartsfield (reporter) 2010-12-17 17:44 |
Yes, qmake-qt4 is in my path. |

You'll have to help me reproduce this problem, because its working for me. I have /usr/bin/qmake (qt3) and /usr/bin/qmake-qt4 (qt4) I inserted messages in FindQt4.cmake as follows: @ -447,7 +447,9 @@ MACRO (_QT4_ADJUST_LIB_VARS _camelCaseBasename) ENDMACRO (_QT4_ADJUST_LIB_VARS) function(_QT4_QUERY_QMAKE VAR RESULT) + message(STATUS "trying ${QT_QMAKE_EXECUTABLE} -query ${VAR}") exec_program(${QT_QMAKE_EXECUTABLE} ARGS "-query ${VAR}" RETURN_VALUE return_code OUTPUT_VARIABLE output ) + message(STATUS "output is ${output}") if(NOT return_code) file(TO_CMAKE_PATH "${output}" output) set(${RESULT} ${output} PARENT_SCOPE) @@ -483,6 +485,7 @@ IF (QT_QMAKE_EXECUTABLE) # check for qt3 qmake and then try and find qmake4 or qmake-qt4 in the path IF(NOT QTVERSION) + message("search for qmake4 or qmake-qt4") SET(QT_QMAKE_EXECUTABLE NOTFOUND CACHE FILEPATH "" FORCE) FIND_PROGRAM(QT_QMAKE_EXECUTABLE NAMES qmake4 qmake-qt4 PATHS "[HKEY_CURRENT_USER\\Software\\Trolltech\\Qt3Versions\\4.0.0;InstallDir]/bin" and the output I get from a run is: ... -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- trying /usr/bin/qmake -query QT_VERSION -- output is **Unknown** search for qmake4 or qmake-qt4 -- trying /usr/bin/qmake-qt4 -query QT_VERSION -- output is 4.6.2 ... |

It looks like that diff is against version 2.8.2, which is the working version; the problem first appears in 2.8.3. I'll look at it further tomorrow if you still don't experience the issue, but it looks like the problem is with the _qt4_query_qmake function; I'm guessing it's not setting the result variable for Qt3 qmake. |

I have the same problem, I'm running cmake 2.8.3 on Ubuntu 10.10. qmake-qt4 is in path. qmake is Qt3 The call _qt4_query_qmake(QT_VERSION QTVERSION) doesn't set QTVERSION if I replace IF("${QTVERSION}" MATCHES "Unknown") with IF(NOT $QTVERSION) then it works for me. Though I haven't tested on a system that doesn't have qt4 installed. |

Oh I see what it is.. this was already fixed last october. http://cmake.org/gitweb?p=cmake.git;a=commit;h=cfba5ef111bf86e8820a4dff556b3a9edc1484cd [^] Can you double check with a 2.8.4 rc? |
