4. Compilation problem

Compilation problem


  • Hi all,

    I'm trying to compile Qt (5.5.1) from git source. It works fine in debug using, but in release mode the compilation fails.

    Here's the configure line for debug mod:

    COMMONOPTS="-opensource -confirm-license -c++11 -shared -largefile -accessibility -no-pulseaudio -no-alsa -no-gtkstyle -nomake examples -nomake tests -no-nis -no-cups -no-iconv -no-icu -no-dbus -opengl -no-libinput -no-gstreamer -qt-xcb"

./configure -prefix ${HOME}/opt/Qt/5.5.1/debug -debug -qml-debug ${COMMONOPTS}

    while in release mode I've used:

    ./configure -prefix ${HOME}/opt/Qt/5.5.1/release -release -no-qml-debug ${COMMONOPTS}

    Note the difference between the two is only -debug -qml-debug vs -release -no-qml-debug.

    In release mode I get compilation errors from something which looks like unicode. But isn't unicode disabled in my build? Here's the error:

    Any idea what could be wrong?

    Hello,
    I believe unicode is enabled by default, it's one of the nice features of Qt. Have you found a switch for the configure script to disable unicode, maybe try it with it (if available)? Have you tried disabling webkit?
    Also, I think 5.5.1 is available precompiled, so maybe consider downloading it directly.

    Kind regards.

    Even if we accept, as the basic tenet of true democracy, that one moron is equal to one genius, is it necessary to go a further step and hold that two morons are better than one genius?

    Hi and welcome to devnet,

    Did you do your release configuration/build in the same folder as your debug build ? If so, you need to first clean the source folder before configuring/building again.

    If you want to avoid that, use an out of source build.

  • @kshegunov Thanks for the reply!

    I started from the precompiled binaries, but for a project I need to compile Qt from source. I did used a flag to disable unicode in my build and this was the source of my surprise: My $COMMONOPTS shown above contains -no-iconv -no-icu which I believed should have disabled it. I'm not sure that my build disables webkit or not; the options in $COMMONOPTS are all I could find from ./configure --help. It takes me ~15 minutes to build Qt so I suspect it is disabled ;)

    @SGaist Thanks! You identified the issue ;)

    I'm placing my build options in $COMMONOPTS to be able to have a debug and release build, installed in ${HOME}/opt/Qt/5.5.1/debug or ${HOME}/opt/Qt/5.5.1/release as required. But I built both in the source directory, starting with debug which compiled and installed successfully. I though re-running configure with the the release flag will let recompile everything, but it seems something went wrong. Note that I could not run make clean in the source directory. There seemed to be an infitine loop where make would tell me some files were not there. Sorry I don't have that output anymore.

    I fix the issue by compiling out of source, for example in build/debug and build/release:

    mkdir -p build/debug
cd build/debug
time ../../configure -prefix ${HOME}/opt/Qt/5.5.1/debug -debug -qml-debug ${COMMONOPTS}
time make -j 4
make install

    and

    mkdir -p build/release
cd build/release
time ../../configure -prefix ${HOME}/opt/Qt/5.5.1/release -release -no-qml-debug ${COMMONOPTS}
time make -j 4
make install

    Both compiled and installed successfully. My program compiles and runs fine with both too.

    Thanks a lot!

    You're welcome !

    Note that you don't need two separate builds, you can ask to get both at the same time.

    Since you have everything running now, please mark the thread as solved using the "Topic Tool" button so that other forum users may know a solution has been found :)
