Welcome to DroidPad! For downloads please visit http://digitalsquid.co.uk/droidpad/
DroidPad is written primarily in C++ with a bit of C dotted around. The source is split into UI parts in src/if-gui and backend code in src/lib. Data (which includes layouts, images, drivers and ADB) is in data/
Other folders: src/lib/ext: external source files used by DroidPad, eg. dns-sd, base64, md5. src/lib/include: include files that include the platform dependent versions. src/lib/msw: MS Windows specific files. src/lib/net: handles network communications. src/lib/usb: manages ADB scanning etc. src/lib/output: platform dependent output functions. src/lib/out/linux: Linux output through uinput src/lib/out/win32: Windows output through Windows API and vJoy src/lib/ext/win32: Windows utils and driver installation.
To compile for Linux, run ./configure; make; (sudo) make install, as is normal for other linux software.
Required installation files to build: build-essential g++ autotools-dev wx2.8-headers libwxgtk-2.8-dev (maybe more?)
I would recommend compiling on a Linux computer, using MinGW.
32-bit: I use the Ubuntu-distributed version of 32-bit MinGW, with wxWidgets compiled into its prefix. 64-bit: I Use my own compiled version of MinGW-64 in a different prefix.
To compile, run ./configure-mingw or ./configure-mingw64. These scripts will need to be changed to use your prefix location from mine. They can also be set with some environment variables. make can then be used to compile the software; make winexport then copies all necessary files to the folder winexport32 or winexport64, allowing for easy running on Windows.
To build a 32 and 64 bit installer, run the script ./winbuild. This requires nsis to be installed.
