TN3270 Protocol Library for Linux/Windows
=========================================

Created originally as part of PW3270 application.

See more details at https://softwarepublico.gov.br/social/pw3270/

Installation repositories
=========================

 You can find instalation repositories in SuSE Build Service:

 * Linux (Many distributions): https://build.opensuse.org/project/show/home:PerryWerneck:pw3270
 * Windows 32 bits: https://build.opensuse.org/project/show/home:PerryWerneck:mingw32
 * Windows 64 bits: https://build.opensuse.org/project/show/home:PerryWerneck:mingw64

Building for Linux
==================

1. Get lib3270 sources from git

	* git clone http://softwarepublico.gov.br/gitlab/pw3270/lib3270.git ./lib3270

2. Install the required libraries

	* autoconf
	* automake
	* binutils
	* coreutils
	* gcc-c++
	* gettext-devel
	* m4
	* pkgconfig
	* openssl-devel
	* dbus-1-devel
	* xz

(This command can make it easy on SuSE: grep -i buildrequires rpm/lib3270.spec | cut -d: -f2 | sudo xargs zypper in )

3. Configure and build

	* ./autogen.sh
	* make clean
	* make Debug


Cross-compiling for Windows
===========================

Cross-compiling on SuSE Linux (Native or WSL)
---------------------------------------------

1. First add the MinGW Repositories for your SuSE version from:

	* 32 bits: https://build.opensuse.org/project/show/windows:mingw:win32
	* 64 bits: https://build.opensuse.org/project/show/windows:mingw:win64

2. Get lib3270 sources from git

	* git clone https://github.com/PerryWerneck/lib3270.git ./lib3270

3. Install cross compilers

	* ./lib3270/win/install-cross.sh --32 (for 32 bits)
	* ./lib3270/win/install-cross.sh --64 (for 64 bits)
	* ./lib3270/win/install-cross.sh --all (for 32 and 64 bits)

3. Configure build

	* ./lib3270/win/win-configure.sh --32 (for 32 bits)
	* ./lib3270/win/win-configure.sh --64 (for 64 bits)

4. Build

	* cd lib3270
	* make clean
	* make all


Compiling for Windows (With MSYS2)
----------------------------------

1. Install MSYS2 

	* Download and install msys2 from https://www.msys2.org/
	* Open a msys2 terminal and run "pacman -Syu" repeatedly
	* Add c:\msys64\usr\bin and c:\msys64\mingw64\bin to system path

2. Install devel packages

	* pacman -S --needed mingw-w64-x86_64-gcc automake autoconf make git openssl pkg-config

3. Get lib3270 sources from git using the mingw shell

	* git clone https://github.com/PerryWerneck/lib3270.git ./lib3270

4. Build library using the mingw shell

	* cd lib3270
	* ./autogen.sh
	* make all
