Eboard program: warning: deprecated conversion from string constant to ‘char*’
 
I am trying, using checkinstall to make eboard to enable use of this program with a DGT electronic chessboard (option not available in the program included in the repositories) according to the instructions given here. After the preliminaries, namely downloading and extracting the source from: http://prdownloads.sourceforge.net/e...-1.1.1.tar.bz2
./configure runs fine but (after su-ing to root), both make install & checkinstall fail after numerous warnings about "deprecated conversion" like:
Code:
board.cc:55: warning: deprecated conversion from string constant to ‘char*’
board.cc:157: warning: deprecated conversion from string constant to ‘char*’
board.cc: In function ‘gboolean board_expose_event(GtkWidget*, GdkEventExpose*, void*)’:
board.cc:1414: warning: deprecated conversion from string constant to ‘char*’
bugpane.cc:304: warning: deprecated conversion from string constant to ‘char*’
So can anyone can offer advice on this? Thank you.

Eboard-1.1.1 : Use g++-4.3 or older , examples :

1) Ubuntu, Debian : Edit the Makefile line 1 to : CXX = g++-4.2
2) Suse : Makefile line 1 : CXX = g++-4.1
3) Fedora, CentOS, RHEL : Makefile line 1 : CXX = g++34


P.S. : Eboard packages (repositories) are available for the most Linux.
Please specify your OS: http://linuxsilo.net/docs/smart-questions_en.html

It worked with g++-4.3 and although there were still a lot of similar warnings as before, I successfully installed the resulting deb package.

True, but it looks like it's necessary to build a package from source to get it to work with a POSIX driver for an electronic board called dgtnix connected to the computer by serial port or USB.

Sorry, I didn't notice ...

The perfect result comes with g++-4.1 : No warnings.

( Using g++-3.4 : Some completely different warnings.)

Thanks again for your help: I'll try g++-4.1
I'll post again, probably in a separate thread regarding getting eboard to work with the dgtnix POSIX driver but I'll link from here in case anyone's interested.
I have only recently started looking at the subject of software packaging so I'm sometimes a bit overwhelmed by the enormous amount of search results obtained for errors and warnings like these so your help is much appreciated and has saved time.
