Problem with code modifications.

Hi i have tried to make a patch for the opencpn-dashboard_pi related to barometric pressure. Everything compile just fine, no errors. But when i run opencpn after "make install", the dashboard plugin does not shows up in the plugin list.
In Opencpn.log this three lines indicate that there is some problem with /libdashboard_pi.so.

- PlugInManager: Loading PlugIn: /usr/local/lib/opencpn/libdashboard_pi.so

- /usr/local/lib/opencpn/libdashboard_pi.so: undefined symbol: _ZN3MDAC1Ev

- PlugInManager: Cannot load library: /usr/local/lib/opencpn/libdashboard_pi.so /usr/local/lib/opencpn/libdashboard_pi.so: undefined symbol: _ZN3MDAC1Ev

Anybody that could lead me into the right track?

I somehow miss the implementation of MDA - you created the header (mda.hpp), but did not implement the class (mda.cpp would be the name of the file).
You should also add the new files into CMakeLists.txt:
Code:
diff --git a/plugins/dashboard_pi/CMakeLists.txt b/plugins/dashboard_pi/CMakeLists.txt
index 8a86528..54d2353 100644
--- a/plugins/dashboard_pi/CMakeLists.txt
+++ b/plugins/dashboard_pi/CMakeLists.txt
@@ -164,6 +164,8 @@ SET(SRC_NMEA0183
     src/nmea0183/mta.hpp
     src/nmea0183/vlw.cpp

Re: Problem with code modifications.

Thank you Pavel(nohal). Some of the problem was related to git, i had not used "git add mda.cpp", and when i tried to apply a patch to a fresh clone of Opencpn these file was not included, The CmakeLists.txt was new for me. Thanks.
