Problems loading static plugins

[Rodrigo]

Hello there!

Since yesterday, i've trying to load a static plugin in my application, but i didn't get good results.

i followed the steps mentioneds at trolltech's site.

1. Add CONFIG += static to your plugin's .pro file.

...
CONFIG += static
...

...
CONFIG += static
...

To copy to clipboard, switch view to plain text mode 

2. Use the Q_IMPORT_PLUGIN() macro in your application.

...
Q_IMPORT_PLUGIN(libxatp)
...

...
Q_IMPORT_PLUGIN(libxatp)
...

To copy to clipboard, switch view to plain text mode 

and finally

3. Link your application with your plugin library using LIBS in the .pro file.

...
LIBS += libxatp.a
...

...
LIBS += libxatp.a
...

To copy to clipboard, switch view to plain text mode 

i tried only put libxatp, but the compiler don't find the file.

g++: libxatp: File or directory not found

how you can see, i followed the steps, but when i compile my project, i get the following error message:

main.o: In function `__static_initialization_and_destruction_0(int, int)':
==== > main.cpp.text+0x1b): undefined reference to `qt_plugin_instance_libxatp()'
collect2: ld returned 1 exit status
make[1]: ** [../bin/xp] Erro 1
make: ** [sub-src-make_default] Erro 2
*** Saiu com estado: 2 ***

I don't know what to do to solve this problem pointed above.

Thank in advance

Try with following:

Plugin (plugin.cpp):

Q_EXPORT_PLUGIN2(xatp, PluginClassName)

Q_EXPORT_PLUGIN2(xatp, PluginClassName)

To copy to clipboard, switch view to plain text mode 

App (main.cpp):

Q_IMPORT_PLUGIN(xatp)

Q_IMPORT_PLUGIN(xatp)

To copy to clipboard, switch view to plain text mode 

In case it still doesn't work, try going through the plug and paint example and your project side by side comparing used macros and file/class names. If still in doubt, attach the project and we'll take a look.

PS. The plug and paint example can be found in <QTDIR>\examples\tools\plugandpaint and <QTDIR>\examples\tools\plugandpaintplugins. You're especially interested into basic tools plugin which is static.

Thanks JPN, i fixed the macro Q_EXPORT_PLUGIN2 and now it works perfectly!
