Thank you very much again ^^ it works !
I made some modification in the text of the about.cpp to make a test and verify it's works well.. I can compile it and run it in Code::Blocks. The changes are visibles and done. That's great ^^
But if I open
OpenCPN from the Ubuntu Lancher, the changes are not applicated like they were when I was compiling in command line terminal. But they are applicated like in Code::Block if I double click on the
Opencpn executable file.. strange ^^ But I think I missed something somewhere else..
Yes I found why, I forgot to do a make install again^^
