Ubuntu10.04, Embeded for arm, I cannot find lipqpng.so in ***/plugins/imageformats???



  • My configure is : ./configure -embedded arm -xplatform /qws/linux-TIarmv7-g++ -host-little-endian -no-pch -no-3dnow -no-cups -nomake examples,demos,docs -no-accessibility -qt-sql-sqlite -no-qt3support -no-javascript-jit -no-script -no-scripttools -qt-zlib -qt-libtiff -qt-libpng -qt-libmng -qt-libjpeg .. And at last i got libqgif.so libqjpeg.so libqsvg.so libqtiff.so libqico.so libqmng.so libqtga.so, but the libqpng.so is missing !

    How to solve the problem ?? My English is poor, its not easy to write tis topic . So thanks for you help in advance.

    Hi and welcome to devnet,

    I might be wrong but IIRC the png support is built-in by default

    I add code in my code:
    qDebug() << QImageReader::supportedImageFormats ();
    and the result :("bmp", "gif", "ico", "jpeg", "jpg", "mng", "pbm", "pgm", "ppm", "svg", "svgz", "tga", "tif", "tiff", "xbm", "xpm"), there is no png support.
    PS:my qt version :qt-everywhere-opensource-src-4.8.5,

    Following the configure script, the png support is built-in so you should have it. The fact that it is not listed is however surprising.

    I got it. I copy the lib files QtEmbeded/lib/lib* to my board /usr/lib/ and the png format is loaded perfect.
    Thanks SG.
