| − | If your plugin does not build with scons, you can use [http://pkgconfig.freedesktop.org pkg-config] to compile it. If you installed yade from debian packages, you have file <tt>/usr/lib/pkgconfig/yade-svn1144.pc</tt> (path will be different from scons installation, see pkg-configu documentation on how to specify path to the .pc file). Using for plugin compilation is as follows: |
||
| − | |||
| − | * Find out what libraries you need to link with |
||
| − | ** rule of thumb: link against all plugins of which headers you include from <code>pkg</code>, <code>lib</code> and <code>extra</code> - for example <code>Box</code>, <code>AABB</code> and <code>InteractingBox</code>. |
||
| − | ** exclude core classes (<code>Omega</code>, <code>Body</code> -- <code>#include<yade/core/Something.hpp></code>), their symbols are defined in yade's executable, you cannot link against them directly. |
||
| − | * Pkg-config will provide you all remaining flags for linker and compiler: you can try yourself that it works: |
||
| − | <pre> $ pkg-config --cflags yade-svn1144 # flags for compiler |
||
| − | -O2 -O3 -ffast-math -pipe -Wall -DLOG4CXX -DEMBED_PYTHON -DSUFFIX="-svn1144" -DPREFIX="/usr" -DYADE_CAST=static_cast -DYADE_PTR_CAST=static_pointer_cast -I/usr/include/yade-svn1144 -I/usr/include/yade-svn1144/yade/lib-miniWm3 -I/usr/share/qt3/include -I/usr/include/python2.5 |
||
| − | $ pkg-config --libs yade-svn1144 # flags for linker |
||
| − | -Wl,-rpath=/usr/lib/yade-svn1144/lib -Wl,-rpath=/usr/lib/yade-svn1144/pkg-common -Wl,-rpath=/usr/lib/yade-svn1144/pkg-dem -Wl,-rpath=/usr/lib/yade-svn1144/pkg-fem -Wl,-rpath=/usr/lib/yade-svn1144/pkg-mass-spring -Wl,-rpath=/usr/lib/yade-svn1144/extra -Wl,-rpath=/usr/lib/yade-svn1144/gui -Xlinker -export-dynamic -rdynamic -shared -L. -L/usr/share/qt3/lib -L/usr/lib/yade-svn1144/lib -L/usr/lib/yade-svn1144/pkg-common -L/usr/lib/yade-svn1144/pkg-dem -L/usr/lib/yade-svn1144/pkg-fem -L/usr/lib/yade-svn1144/pkg-mass-spring -L/usr/lib/yade-svn1144/extra -L/usr/lib/yade-svn1144/gui -lpython2.5 |
||
| − | </pre> |
||
| − | Note that this will ensure consistency between header and library versions. |
||
| − | * Compile your plugin like this: |
||
| − | |||
| − | g++ `pkg-config --cflags --libs yade-svn1145` MyPluginForYade.cpp -o MyPluginForYade -lAABB -lBox -lShop |
||
| − | |||
| − | * Edit the file <tt>~/.yade-svn1144/preferences.xml</tt>, add path to <tt>libmyPlugin1.so</tt> (suppose it is /home/fred/prog/yade) to dynLibDirectories: |
||
| − | <Yade> |
||
| − | <preferences _className_="Preferences" version="1" dynlibDirectories="[/usr/lib/yade-svn1144/extra /usr/lib/yade-svn1144/gui /usr/lib/yade-svn1144/lib /usr/lib/yade-svn1144/pkg-common /usr/lib/yade-svn1144/pkg-dem /usr/lib/yade-svn1144/pkg-fem /usr/lib/yade-svn1144/pkg-lattice /home/fred/prog/yade]" includeDirectories="[]" defaultGUILibName="QtGUI" /> |
||
| − | </Yade> |
||
| − | * Run yade, it should load your plugin now. |
||
| − | |||
| − | '''Warning''': if you load this plugin with different version of yade, yade will not stop you and it will very likely crash. |
