Dear all,
Hi, I'm new to libreoffice and its forum. I have a question but I am
not sure where to ask. If this is the right place, here is the question :)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Question:
I have successfully added a new dialog in Impress according to the
steps in this tutorial - Development/Create new dialog in Impress -
The Document Foundation Wiki
<https://wiki.documentfoundation.org/Development/Create_new_dialog_in_Impress>.
Now I wish to call functions in an external library in the dialog
source file.
I have an external library *libxxx* containing some C++ header files
and a .so file. I put the header files in include/ folder and .so file
outside libreoffice directory. I include the header files of this
library in dialog source files located in sd/source/ui/dlg. I rerun
the autogen.sh with extra arguments, trying to let the build system
know I have a .so library to link.
./autogen.sh LDFLAGS=-L/path_to_libxxx LIBS=-lxxx
Then I rebuild the sd module using make sd, however, it seems the
functions in .so library is not properly linked.
"/usr/bin/ld:
/home/jingze_xu/office/libreoffice-7.6.0.0.beta1/workdir/CxxObject/sd/source/ui/dlg/HelloDialog.o:
in function `sd::SdHelloDialog::OKHdl(weld::Button&)':

`Add_FileHeader(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> >,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >, unsigned short)'
collect2: error: ld returned 1 exit status
make[1]: ***

/home/jingze_xu/office/libreoffice-7.6.0.0.beta1/instdir/program/libsduilo.so]
Error 1
make: *** [Makefile:121: sd] Error 2"
Are there some clues about linking so library in libreoffice codebase?
Thanks!

and please tell me where to ask questions. Thanks!
