Written from scratch in C
The GUI has been written in GTK+
About the core, it's all written in 3 libraries, one for the math functions, other for processing the expressions, and the third with some common functions like string handling.
To build the project you can use cmake
$ mkdir -p build && cd build
$ cmake ..
$ make
Also some makefiles are left from previous attempts
You can run the GUI simply by double clicking the generated executable or by command line
build $ ./sscalc-gui
Also the program can be run from the terminal (currently not working)
build $ ./sscalc
