<div style="line-height:1.7;color:#000000;font-size:14px;font-family:Arial"><div style="margin:0;">Dear all, </div><div style="margin:0;"><br></div><div style="margin:0;">Hi! I have added a new dialog in Impress according to this article <a href="https://wiki.documentfoundation.org/Development/Create_new_dialog_in_Impress">Development/Create new dialog in Impress - The Document Foundation Wiki</a>. However, this article was written in 2013 and too old for the current version. I attached a updated article that suits for version 7.6.0. I hope it can help update the official article. </div><div style="margin:0;"><br></div><div style="margin:0;">After I added the new dialog, I have been trying to use external shared libraries in the dialog source file, according to this <a href="https://github.com/LibreOffice/core/commit/a2ffd71f20e14f797f30223fe29b3ac1e92eafdf">build libtiff бд LibreOffice/core@a2ffd71 (github.com)</a>. The external library I added simply contains a header file which has a helloWorld function and a .so file. I encoutered a problem. </div><div style="margin:0;">------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------</div><div style="margin:0;">I found that after doing all steps in the link above, I still need to add [path to my .so library directory] to system environment variable $LD_LIBRARY_PATH to make it work. I tried to add ldflags in RepositoryExternal.mk but it didn't work. (The part that has been commented out). How</div><div style="margin:0;">to make it work without setting system environment variable? I think </div><div style="margin:0;"><span style="font-family: Consolas, "Courier New", monospace; white-space: pre; color: rgb(206, 145, 120);">$(</span><span style="font-family: Consolas, "Courier
