This is a simple C++ application that can convert ODT or other document files using LibreOffice SDK into PDF or other LibreOffice supported file types. This application is using qmake or cmake in order to compile, execute and debug easier using Qt Creator. To keep it simple, the arguments are not processed, and the input file is the ~/test.odt, and the output will be ~/test.pdf.

To be able to compile and run this example, you should have installed LibreOffice and LibreOffice SDK, then you should set LOROOT in loconvertor.pro to appropriate folder. For LibreOffice 7.6 SDK, you should use this line:

LOROOT = /opt/libreoffice7.6

Compiling and running the loconvertor is easy. First, run an instance of LibreOffice to listen for the incoming connections:

$ libreoffice7.6 "--accept=socket,port=2083;urp;"

and then just open the project file in Qt Creator, and click Run or press Ctrl+R. Both cmake and qmake should can be used.

If you have built LibreOffice yourself, use the instdir path for LOROOT:

LOROOT = /home/hossein/Projects/libreoffice/core/instdir

In such case, the above symbolic link is not needed, and should not be created.

If you use a local build, run:

$ ./instdir/program/soffice.bin "--accept=socket,port=2083;urp;"

And execute the project from Qt Creator.

To run loconvertor from command line using cmake, go to the source folder, and then:

$ mkdir build
$ cd build
$ cmake ..
$ make
$ ./loconvertor
