    Hello, I am running qt 4.7.0 with some QML code on a embedded ARM system. When I start the app I see:

    QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv failed for BOM: Bad file descriptor
    QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
    QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed

    And the fonts are square boxes in the app. Any suggestions as to what is wrong, or how I can debug?

    I'm running Qt on top of X11.

    Thanks,
    Cliff

      the QIconvCodec messages appear to be benign.

      The problem with the square boxes for fonts was simply that I did not have ttf fonts installed on my target system.

            The original problem seemed to have been missing fonts. Without more information about what you're trying to do, we won't be able to help you.

              I am just trying to launch a Qt app.
              How can I know which fonts Qt is trying to use ?
              Where the fonts are supposed to be ?
              Because I have fonts installed on my system, I can see them using fc-list.

              An exemple of the problem :

                Solved it !

                I needed to update the xorg.conf file :

                Section "Files"
                FontPath "/usr/share/fonts/X11/100dpi"
                FontPath "/usr/share/fonts/X11/75dpi"
                FontPath "/usr/share/fonts/default/ghostscript"
                ....
                EndSection

                I still have the error message, but the fonts are displaying correctly...

                  Hi, excuse me if the thread I'm reviving is already quite old, but I don't see a suggested solution here. I"m currently debugging something, so I'd like to cover alle the bases. I don't think it keeps the app from functioning, but who knows...

                  I am having the same error message when I start any applications, using Qt 5 with the EglFS and Wayland plugins.

                  bq. QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed
                  QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed

                  Any ideas what this could be? I don't have X, and all fonts are installed... I've been working on Qt 5 since around 2 months now, and it appeared just recently.

                  I am also working on an ARM platform. Freescale i.MX515 to be exact.

                    It seems that your Qt libs are not correct versions on target platform. you can copy libQtCore and other needed libs to your target platform Qt lib path.

                        After make install I am able to find all the cross compiled libraries. But I counld not find the fonts folder.
                        I copied all the libraries onto my target and tried executing some application but I am gettitng error as follows.
