  • Configure
  • Just click the Run or Build button, the Vaa3D will run.

Vaa3D Plug-in

  • Clone the Vaa3D plugin source code from here
$ git clone -b vaa3d_tools_qt6 https://github.com/Vaa3D/vaa3d_tools.git

Note

Vaa3D's main program folder (for example) needs to be placed at the same level as the plugins folder, which is needed to compile the script, and the file structure is shown in the diagram

+ ----------------
+ v3d_external/...
+ vaa3d_tool/...
+ ----------------
  • Configure Qt environment variables so that the script can execute qmake globally
$ sudo vim /etc/profile
---------------------------------------
...
# in profile file add
export QTDIR=/<your path>/Qt/6.2.2
export PATH="$QTDIR/gcc_64/bin:$PATH"
export LD_LIBRARY_PATH=$QTDIR/gcc_64/lib
----------------------------------------
$ sudo source /etc/profile

Note: You can verify that the settings are successful by using qmake -v

  • Setting soft links to documents
$ cd vaa3d_tools
$ ln -s ../v3d_external/v3d_main v3d_main
$ ln -s ../v3d_external/bin bin
$ cd ../v3d_external
$ ln -s ../vaa3d_tools/released_plugins released_plugins_more
