To build FreeShip from sources you will need Lazarus 2.0.* FPC 3.0.4 

Use project options FreeShip.lpi 
Adjust Config and  Target to Gtk2 or win32 and and to your OS environment.
Unselect "Win32 gui application" because for time being some output goes to console 

You do not need Qt4 anymore.

In Windows

you need git for Windows. Please set it to upload texts in Unix style.
Also you need: 
- Cygwin with following packages: sed,grep,binutils,file,cut,git,zip,imagemagic
- MinGW32 to build FreeShip
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dll

copy these libraries into project root


In Linux

install packages:
libmagic.dev


Packaging

If you want to package installation package you should run release.sh
Some prerequisites have to be fulfilled first: 
 - build versinfo utility. Build Utils/versinfo.lpi
 - release.sh and zipbin.sh are Bash scripts that call some non-windows utils: md5sum, grep, sed, file, cut, zip.
   In Linux you usually already have them out of box. If not, please install.
   In Windows you need to install something like Cygwin, as it mentioned above, or Msys2.
   Good recent news: In Windows 10 these binaries can be installed natively (from Ubuntu) and you can use Bash as command line.


Cross compilation from Linux smd64 to Linux i386


Follow Lazarus Cross Compilation to make cross compilation till simple test.pas start working 

Here is Ubuntu setup

Install following packages:
 sudo apt install gcc-multilib
 sudo apt install libx11-dev:i386
 sudo apt install pixbuf2.0-0:i386
 sudo apt install libgtk2.0-0:i386
 sudo apt install libpangocairo-1.0-0:i386
 sudo apt install libmagic-dev:i386

 sudo ln -s -f /usr/lib/i386-linux-gnu/libpangocairo-1.0.so.0 /usr/lib/i386-linux-gnu/libpangocairo-1.0.so

In project settings set target i386.

Good luck!
