Compiling 2.1 on Linux with QT-Creator
Locked
 
|
Hello,
as I wanted to test some things with version 2.1 and eventually also include my PR regarding fingerings on tablature, I tried to compile 2.1 with QT-Creator, but didn't get around with an error: #error "You must build your code with position independent code if Qt was built with -reduce-relocations. " "Compile your code with -fPIC (-fPIE is not enough)." # error "You must build your code with position independent code if Qt was built with -reduce-relocations. "\ ^ Does someone know, how to get around this problem? Best regards Markus -- Markus Lutz Schulstraße 11 88422 Bad Buchau Tel 0 75 82 / 92 62 89 Fax 0 75 82 / 92 62 90 Mail [hidden email] |

On which OS ?

You will need Qt 5.4 for MuseScore 2.1 I'm afraid. lasconic 2017-02-28 19:58 GMT+01:00 MLutz <[hidden email]>: lasconic wrote ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Mscore-developer mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/mscore-developer |

At least it doesn't seem to be a problem of the qt version. With 5.4 I have the same problem ... I tried to set the Compiler Flags within MuseScore2.1.config, but it doesn't work also: #define CMAKE_CXX_FLAGS_DEBUG "-std=c++11 -fPIC -fPIE -g -reduce-relocations" #define CMAKE_CXX_FLAGS_RELEASE "-std=c++11 -fPIC -O2 -DNDEBUG -DQT_NO_DEBUG" Does someone has further advice? |

You can use the settings from git head branch (3.0) which should work.

No, this is not a Qt Version Problem at thois point. That change was introduced in Qt5.4.2 - see http://code.qt.io/cgit/qt/qtbase.git/plain/dist/changes-5.4.2. > I tried to set the Compiler Flags within MuseScore2.1.config, but it doesn't > work also: > #define CMAKE_CXX_FLAGS_DEBUG "-std=c++11 -fPIC -fPIE -g > -reduce-relocations" > #define CMAKE_CXX_FLAGS_RELEASE "-std=c++11 -fPIC -O2 -DNDEBUG > -DQT_NO_DEBUG" > > Does someone has further advice? I think Cmake has specific magic for that.

I've definitely seen that error before, but it always turned out to be something I had done wrong in my cmake configuration within QtCreator. Like I left out the CMAKE_BUILD_TYPE=DEBUG, or the -G"Unix Makefiles", or I didn't do a make clean after a previous build attempt with bad configuration, etc. Marc On Tue, Feb 28, 2017 at 2:32 PM Werner Schweer <[hidden email]> wrote: You can use the settings from git head branch (3.0) which should work. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Mscore-developer mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/mscore-developer |

Thank you very much for all the help.
It finally worked, as soon as I deleted the "-fPIE" from line 163 of CMakeLists.txt. All other tries were in vain ... |

Are you shure the binary runs stable? AFAAIK you really need the -fpic flag to compile against newer Qt5 versions (unless you compiled Qt yourself and disabled Qt's "reduce relocations"). From Qt's changelog: - On x86 and x86-64 systems with ELF binaries (especially Linux), due to a new optimization in GCC 5.x in combination with a recent version of GNU binutils, compiling Qt applications with -fPIE is no longer enough with GCC 5.x. Applications now need to be compiled with the -fPIC option if Qt's option "reduce relocations" is active. For backward compatibility only, Qt accepts the use of -fPIE for GCC 4.x versions. Note that Clang is known to generate incompatible code even with -fPIC if the -flto option is active. Applications using qmake or cmake >= 2.8.12 as their build system will adapt automatically. Applications using an older release of cmake in combination with GCC 5.x need to change their CMakeLists.txt to add Qt5Core_EXECUTABLE_COMPILE_FLAGS to CMAKE_CXX_FLAGS. In particular, applications using cmake >= 2.8.9 and < 2.8.11 will continue to build with the -fPIE option and invoke the special compatibility mode if using GCC 4.x.

As far as I can see, it works fine. The -fPIC option is set in CMakeLists.txt. See the lines: set(CMAKE_CXX_FLAGS_DEBUG "-std=c++11 -fPIC -fPIE -g") set(CMAKE_CXX_FLAGS_RELEASE "-std=c++11 -fPIC -O2 -DNDEBUG -DQT_NO_DEBUG") I only deleted the -fPIE, and now everything works ...
