gdcalc - a gtk+ RPN calculator
To build in Linux, you should be able to:
./autogen.sh
make
... and then install in your favourite place: cp gdcalc /usr/local/bin
I have included a nice icon for the program that I use (with fvwm2):
cp HP-16C-48.xpm /usr/share/icons
cp mini-HP-16C-48.xpm /usr/share/icons
... or wherever you like to keep things.
You might need to do a little more magic to get the icons to work with Gnome, KDE or other window manager.
There is a sample resource file gdcalcrc with my favourite fonts. Customise and install as ~/.gdcalc.rc
