qpdfview

qpdfview on mac

Asked by Petr Vokac

Hi,
I am trying to install qpdfview on Mac.
I have macports installed.
I have qt4 installed.
I did steps "qmake qpdfview.pro" and "make".
For "make install" I have changed target directory from /usr to /opt/local.
That is all OK, but where is the executable?
I found /opt/local/bin/qpdfview.app,
but it does not work: "Could not load plug-in for file type 'PDF'!".

Thank you for any hint,
Petr

Hello Petr,

qpdfview has never been properly ported to and tested on Mac OS X and since I do not have access to a machine running it, I won't be able to really help you with this...

The concrete error in question looks like it searches for its plug-in libraries in the wrong places and you probably want to adjust the various paths in qpdfview.pri, e.g. PLUGIN_INSTALL_PATH. You probably also want to override the qmake variable PDF_PLUGIN_NAME which is assumed to be "libqpdfview_pdf.so" but will probably rather look like "libqpdfview_pdf.dylib" or something similar on Darwin.

In any case, if you run qpdfview from a terminal it should print out some diagnostic messages about where it is looking for the plug-ins. It usually begin in the same directory as the application binary itself and then try again in PLUGIN_INSTALL_PATH defined above.

Best regards, Adam.

Hello Adam,

thank you for answer.

I tried to run the code from the command line and I got:

pvmb:MacOS pet$ ./qpdfview &
pvmb:MacOS pet$ QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:
QSqlError(-1, "Driver not loaded", "Driver not loaded")

So I installed some sqlite plugin:
sudo port install qt4-mac-sqlite3-plugin

And this error disappeared. I added PDF_PLUGIN_NAME to qpdfview.pri, which now contains:

isEmpty(APPLICATION_VERSION):APPLICATION_VERSION = 0.4.16

isEmpty(TARGET_INSTALL_PATH):TARGET_INSTALL_PATH = /opt/local/bin
isEmpty(PLUGIN_INSTALL_PATH):PLUGIN_INSTALL_PATH = /opt/local/lib/qpdfview
isEmpty(PDF_PLUGIN_NAME):PDF_PLUGIN_NAME = libqpdfview_pdf.dylib
isEmpty(DATA_INSTALL_PATH):DATA_INSTALL_PATH = /opt/local/share/qpdfview
isEmpty(MANUAL_INSTALL_PATH):MANUAL_INSTALL_PATH = /opt/local/share/man/man1
isEmpty(ICON_INSTALL_PATH):ICON_INSTALL_PATH = /opt/local/share/icons/hicolor/scalable/apps
isEmpty(LAUNCHER_INSTALL_PATH):LAUNCHER_INSTALL_PATH = /opt/local/share/applications
isEmpty(APPDATA_INSTALL_PATH):APPDATA_INSTALL_PATH = /opt/local/share/appdata

And I did qmake and make again.
Unfortunately qpdfview still does not work.
I got again the message box with "pdf plugin not found"

Here is the output from the commandline:

Hello again,

there is a problem in the error reporting of qpdfview here:

Could not load plug-in in first attempt: ""
"Nepodařilo se nalézt sdílenou knihovnu."
Could not load plug-in in second attempt: ""
"Nepodařilo se nalézt sdílenou knihovnu."

We try to print "QPluginLoader::fileName" which is not set if the library could not be loaded. Sorry about that, I will push a fix to trunk which will make the error messages more useful ASAP. Please try again with the latest code from trunk after that.

Best regards, Adam.
